We have not had to look at online reviews for years because our customers share their views directly with us.
Since Feb 2026, we have been alerted to updates on Google and Reddit that warrant our attention.
We would like to share the timeline of events as we know:
A tutor left Singapore Learner (SL).
Some time around late Feb 2026, within the SAME week 7 google reviews were posted about Singapore Learner, all of which gave 1 star to SL and a number of them gave 5 stars to just one particular learning centre. We have the photo evidence of this which we submitted to Google to report these suspicious activities. As a result, Google investigated and found these posts worthy of being removed.
Then 2 more suspicious Google reviews were posted, but this time giving SL 5 stars but asking the reader to do their “due diligence” in reddit.
The questionable reddit comments made after Google’s intervention (some time in Mar 2026) carry the same tone as the reviews removed by Google.
We would like to invite parents and students to find out more about our services by contacting us directly and visiting our centre.
To our existing students and their parents, your feedback about our services is most welcome and you can come to us directly.
Singapore Learner has been a Comprehensive Science Practical Training provider since 2017.
As at 19 Apr 2026, we have trained about 1060 students for their science practical exams and we have conducted a total of about 4044 lab sessions.
Our laboratory apparatus are exam-grade and similar to those used in MOE schools and our chemicals are all NEA-approved.
We provide A-Level / H2 / IP and O-Level Physics, Chemistry, Biology and CombinedScience (Physics/Chemistry/Biology) PracticalTraining/Crash Course/Mock Exams for both local (eg. H2, Singapore-Cambridge) and international exams (CIE, Pearson Edexcel, IGCSE).
Decide which examination system (Singapore-Cambridge, CIE etc.) you wish to train students for.
Decide which level(s) (A or O) and which subjects (Biology, Chemistry etc.) for your practical programme.
Read thoroughly the science practical syllabus for each level and subject. Take note of the Assessment Objectives, Exam Paper format and the list of apparatus and chemicals needed for each level and subject.
Choose a suitable location, building and unit for your science lab. Please note that for Biology and Chemistry, your lab must have windows which can be opened for ventilation purposes.
Install fire safety systems and devices in your lab, as well as subject-specific safety equipment such as chemical shower facility for chemistry.
Create all the worksheets (at least 10), prep lists and suggested answers for subject and level.
Purchase and store all the apparatus and chemicals you will need.
Equip your lab with the right furniture and standard bench reagents and devices such as retort stands and portable burners.
Hire Lab Assistants to help you manage the lab.
Hire teachers or tutors who are comfortable with conducting lab sessions.
PREPARING A SCIENCE EXPERIMENT
About two weeks before the date of the expt, scrutinize its prep list and check for items which you may need to purchase immediately, as suppliers may take a week to send them.
Lab Asst to prepare all the apparatus and chemicals according to specifications, such as quantity, mass or concentration of a substance, including spare apparatus and chemicals. Every bottle has to be labelled.
Lab Asst to layout all the items and chemicals for each student.
Lab Asst to ensure that all the bench reagents and consumables have been topped up.
All the lab worksheets, notes and answers must be printed.
At the end of the experiment, all the used test-tubes, bottles, beakers etc. have to be washed and dried, and other apparatus have to be stored.
SUSTAINING A SCIENCE PRACTICAL TRAINING PROGRAMME
Weekly schedules have to be updated to cater to various student groups, subjects and levels.
Lab rooms have to be assigned to different groups or experiments for laying out of apparatus.
Enough teachers and lab assistants have to be deployed throughout the week; while several experiments are being conducted, future experiments have to be prepared.
Planning must include disposal of waste chemicals and broken glass, and repair or disposal of spoilt items.
Consumables must be ordered before the current ones run out.
Worksheets and notes may have to be updated if there is a change of syllabus, or a change in question trends.
If you are a tuition centre, your practical training programme needs to be marketed via ads in social media or mass media.
To be continued …….

In chemistry, qualitative analysis refers to the process of identifying what substances are present in an unknown sample. The emphasis is on the properties and reactions observed, rather than numeric measurements.
During qualitative analysis, you focus on:
the appearance of a substance;
colour changes or changes in physical state, such as the formation of a precipitate (solid) or the evolution of a gas; and
the interaction of the substance with test reagents such as litmus paper.
This differs from quantitative or volumetric analysis, which involves taking measurements to determine the amount or concentration of a substance.
You should be familiar with the standard chemical tests for the following ions and gases:
No practical tests involving sulfur dioxide are required.
A positive acidity test indicates the presence of H⁺ ions, whereas a positive alkalinity test shows the presence of OH⁻ ions.
General Guidelines for QA
Experimental Techniques and Skills
1. Apparatus
Use test‑tubes or boiling tubes to perform most tests. Boiling tubes are slightly larger and more heat‑resistant than standard test‑tubes.
Check that all glassware is clean, dry, and free from cracks before use.
For accurate colour observation, hold the test‑tube against a white tile or sheet of white paper for contrast.
2. Samples
Use a spatula for solids and a dropper for small liquid volumes.
Unless otherwise instructed, use:
not more than 1 cm depth of solid, or
not more than 2 cm depth of solution in a test‑tube.
Using excess samples can obscure reactions or cause safety hazards.
3. Technique
Work carefully and deliberately.
Unless stated otherwise, add reagents drop by drop.
Prepare all materials beforehand so you can focus on one test at a time.
When heating:
Hold the test‑tube with tongs or a holder.
Begin with gentle heating before increasing intensity.
Always point the mouth of the test‑tubeaway from yourself and others.
If the reaction becomes vigorous, remove it from the flame immediately.
Making and Recording Observations
After each test:
Record your observations immediately while they’re fresh.
Draw inferences and conclusions clearly and accurately.
Summarise these in your practical notes or report.
When recording data:
Include ALL noticeable observations — colour changes, precipitates formed, and gases evolved.
Use clear, specific terminology so that another person could replicate or understand your results easily.
1. Describing Colours
Always describe every colour change that takes place.
Use simple, accurate colour descriptions such as “blue,” “green,” “yellow,” “orange,” “brown,” “white,” or “black.”
If mixed colours appear and no exact shade can be determined, use compound terms such as red‑brown, blue‑green, or yellow‑green.
Avoid imprecise or hybrid colour phrases like red‑yellow (when “orange” is more accurate).
The words light or dark may be used for shades.
If a gas or liquid is clear and has no colour, describe it as colourless, not white.
2. States of Matter and Their Descriptions
(a) Solids
Describe solids as crystalline, powdery, or metallic in appearance.
When two solutions form an insoluble solid, that solid is called a precipitate.
A solid forming on another surface is a deposit, and one remaining after heating or filtration is a residue.
(b) Liquids
A solution is a uniform mixture of solute and solvent.
A cloudy or turbid liquid indicates a suspension — tiny particles are dispersed but not dissolved.
(c) Gases
Observe whether gases have distinctive smells but never inhale directly — waft gently toward your nose instead.
A solid that forms when a gas cools is called a sublimate or deposit.
(d) Changes Upon Heating
A solid may convert into another solid (residue) of different appearance.
Some solids decompose completely and leave no solid.
A few solids sublime, turning directly into gas.
When bubbles form in a liquid as a gas evolves, describe the observation as “effervescence is observed” instead of simply “a gas is produced.”
Procedures and Observations for Tests
Test for Aqueous Cations
Cations are typically identified using aqueous sodium hydroxide (NaOH) and aqueous ammonia (NH₄OH).
Procedure:
Place about 2 cm of the unknown solution into a test‑tube.
Tilt the tube slightly and add the reagent slowly down the side.
Observe any colour change or precipitate.
Return the tube upright and swirl gently.
Continue adding reagent in excess until no further change occurs.
Observation Checklist:
Whether a precipitate forms
Colour of the precipitate
Whether it is soluble in excess reagent
If ammonia gas is released when using NaOH

Note: Iron(II) hydroxide quickly oxidises in air to form brown iron(III) hydroxide.
If no precipitate appears with NaOH and no ammonia is evolved, the cation is likely a Group I metal (e.g. Na⁺, K⁺).
Test for Aqueous Anions
Anions are tested systematically using dilute nitric acid (HNO₃) first to eliminate interfering ions. When testing for nitrate, you must use another reagent because nitric acid itself contains nitrate ions.
Phase 1 : Test for Carbonate (CO₃²⁻) Add about 2 cm of the unknown sample to a test‑tube. Place a drop on red litmus paper. If the paper turns blue, add a few drops of dilute nitric acid. If effervescence occurs, confirm with the limewater test. A white ppt that dissolves on further bubbling proves the presence of carbonate ions (CO₃²⁻). If no gas forms, the sample is an alkali (contains OH⁻). If litmus stays red, move to the next phase.
Phase 2 : Test for Chloride (Cl⁻) or Iodide (Pure Chem) Acidify the solution from Phase 1 with nitric acid. Add aqueous silver nitrate down the side of the tube. Observation of a white precipitate confirms chloride ions. (Pure Chem: if a yellow ppt. is observed, then iodide ions confirmed) If no ppt forms, proceed to Phase 3.
Phase 3 : Test for Sulfate (SO₄²⁻) Add aqueous barium nitrate (Ba(NO₃)₂) to the previous acidified mixture. Formation of a white precipitate confirms sulfate ions (SO₄²⁻). If no ppt forms, proceed to Phase 4.
Phase 4 : Test for Nitrate (NO₃⁻) Place fresh solution (no nitric acid added) in a clean tube. Add aqueous sodium hydroxide and a small piece of aluminium foil. Warm gently. Test the gas with damp red litmus paper – if it turns blue, ammonia gas is produced, confirming nitrate ions.
Summary Table: Tests and Observations for Common Anions
Anion
Test
Observation
Carbonate ion (CO₃²⁻)
1. Test the solution with red litmus paper.
Red litmus paper turns blue.
2. Add dilute nitric acid.
Effervescence is observed.
3. Test for CO2by bubbling the gas through limewater.
The gas produced, CO2, forms a white precipitate of calcium carbonate in limewater that dissolves after more bubbling.
Chloride ion (Cl⁻)
Add dilute nitric acid, then aqueous silver nitrate.
Formation of a white precipitate of silver chloride (AgCl).
Sulfate ion (SO₄²⁻)
Add dilute nitric acid, then aqueous barium nitrate.
Formation of a white precipitate of barium sulfate (BaSO₄).
Nitrate (NO₃⁻)
1. Add NaOH and aluminium foil, then warm.
Effervescence is observed.
2. Test for ammonia gas with damp red litmus paper.
The gas produced, ammonia gas, turns damp red litmus paper blue.
Notes:
Always eliminate hydroxide and carbonate ions first using litmus and acid tests.
Test for nitrate only when other ions have been ruled out.
Test for Gases These procedures help you identify gases by their effects and reactions.
Phase 1: Determine Acidic, Basic, or Neutral Gas Hold damp red and blue litmus papers near the gas source. Red → Blue → Gas is ammonia (NH₃). Blue → Red → Could be CO₂, SO₂, or Cl₂ (proceed to Phase 2). Blue → Red then bleached → Chlorine (Cl₂) or Sulfur dioxide (SO₂). No change → Gas is neutral (H₂ or O₂). ⚠️ A yellow‑green gas indicates concentrated chlorine – a severe inhalation hazard.
Phase 2 : Testing Acidic Gases If blue litmus turns red (not bleached): bubble gas through limewater. A white precipitate dissolving in excess gas → Carbon dioxide. If blue litmus turns red and bleaches: hold acidified potassium manganate(VII) paper at tube mouth. Paper turns from purple to colourless → Sulfur dioxide. Paper stays purple → Chlorine. (Chlorine can also turn potassium iodide‑starch paper blue, but this confirmatory test is usually unnecessary.)
Phase 3 : Testing Neutral Gases Add a metal and apply a burning splint: “pop” sound → Hydrogen. Without metal, insert a glowing splint: relights → Oxygen.

The second question (8m) was on oscillations, where there was a short stick with two metal balls hanging from it by strings, and a diagonal stick crossing the strings which allowed the length of string to be varied and hence the period of oscillation.
The third question (22m) was on forces where students had to build a cantilever by hanging one edge of a meter rule off the table while the other edge remained on the table, and placing weights on it to find the balance point, then do calculations.
The planning question was on measuring background radioactivity count rate for different distances from a building and from the ground.
What you will get at each practical session:
(1) Teaching and instruction on how to use the various scientific tools and instruments.
(2) Tips on how to answer a practical worksheet or exam paper, including recording of observations, drawing graphs, writing conclusions, describing precautions and planning a practical.

IMPORTANT INFORMATION FOR PRIVATE CANDIDATES
The registration for ‘A’ and ‘O’ Level exams as a private candidate usually opens around early to mid-April (Please check SEAB website). If you are registering for a Science subject (Physics, Chemistry, Biology or Combined Sciences), at the time of registration in April, you will be asked whether you have done any science practical training in any school, centre, or institute.
Thus if you are considering Singapore Learner as your science practical training provider, you are strongly advised to register with us and begin your science practical sessions for each subject BEFORE APRIL for us to certify that you have attended basic science practical training. Thus it is recommended that you commence practical training with us in Jan/Feb. Please note students usually do about 10 practical sessions per subject to be competent in practicals.
The following is taken from SEAB website:
“If you are registering for a Science subject with a practical paper, you: • Must have sat the same Science subject(s) previously, OR • are currently attending or will be attending a course of instruction in Science practical at any institute/school. You must complete the course of instruction in Science practical at the institute/school enrolled in. You are required to declare that you have fulfilled the above requirements at the point of registration.Registration for the subject may be cancelled without a refund of the examination fees if a false declaration is made.“

Attention 2026 A-Level Students!
Did you know there are updates to the A-Level Science syllabus?
Curious about the changes?
Don’t worry—Singapore Learner’s tutors have got you covered!
Changes to ALL Sciences:
The marks for ALL SCIENCES Practical has been reduced from 55 marks to 50 marks, while the weightage remains at 20 %.
Additionally, the Planning (P) component reduced from 5 % to 4 %, while other components (Manipulation, measurement and observation (MMO), Presentation of data and observations (PDO) and Analysis, conclusions and evaluation (ACE)) increased from 15 % to 16 %. This suggests that students should focus less on the planning component and more on the othercomponents!
As for the assessment objectives, knowledge with understanding is now more worth at 36 % (from 32 %) than handling, applying and evaluating at 44 % (from 48 %). (In layman terms, this means that the questions are set slightly MORE towards remembering and understanding the content THAN application questions).
For Paper 3 (Structured Questions), the total marks has now decreased from 80 marks to 75 marks, with from Section A (Long Structured Question) decreased from 60 marks to 55 marks. Weightage of Paper 3 (35 %) and marks from Section B (20 marks) remains.
Clearer wordings in the learning outcomes (L.O), which includes
For discussion of effects on the entropy of a chemical system, “mixing of particles” is NO LONGER REQUIRED.
Instead of “describing enzymes as biological catalysts which may have specific activity” and “explaining the relationship between substrate concentration and the rate of an enzyme-catalysed reaction in biochemical systems“, candidates are now require to “describe enzymes as protein molecules that act as biological catalysts with high specificity (in the reactions that they catalyse and in their choice of substrates as exemplified by the lock-and-key model), temperature sensitivity and pH sensitivity [knowledge of the levels of structure of proteins and the details of the denaturation process are not required]. (I can forsee the H2 Biology Students smiling…)
Instead of using buffer solutions (CO32–/HCO3–) to explain controlling pH in blood, it used to explain maintaining pH in oceans, and how the rapid increase in atmospheric carbon dioxide gas contributed to ocean acidification.
Inclusion of reagents and conditions in the L.Os.
With inclusion to recognise the effect of chlorofluoroalkanes (CFCs) on the ozone layer, candidates are also required to recognise their proposed replacements, hydrofluoroalkanes (HFCs) and hydrochlorofluoroalkanes (HCFCs), having significant environmental impact too.
Proteins are no longer part of the nitrogen compounds chapter, but in the polymer chapter. Emphasis on the fact that proteins are example of condensation polymerisation.
Redefined the definition of transition element as “a d block element whose atom has an incomplete d subshell, or which can give rise to cations with an incomplete d subshell”.
NEW CHAPTER: POLYMER
Recognisepolymers as macromolecules built up from monomers, with average relative molecular mass of at least 1000 or at least 100 repeat units
Classify and explain the difference between addition polymers (as exemplified by poly(alkenes)) and condensation polymers (as exemplified by polyesters and polyamides)
Recognise that poly(alkenes) are chemically inert and can therefore be difficult to biodegrade
Recognise that polyesters and polyamides are generally biodegradable by hydrolysis
Recognise that materials are a finite resource and the importance of recycling plastics, considering the economic, environmental and social factors
9476 candidates NO LONGERneed to:
Show understanding that the position of equilibrium is dependent on the standard Gibbs free energy change of reaction, ΔG⦵.
Recognise that petroleum, a chemical feedstock, is a finite resource and the importance of recycling.
Description of the formation of zwitterions.
For Paper 4 (Practical), 9476 candidates:
NO LONGERneed to carry out organic QA tests involving 2,4-dinitrophenylhydrazine, phosphorus(V) chloride or phenol.
NO LONGERrequired to carry out gas collection experiments involving displacement of water or using gas syringes.
Additionally, the organic QA table is NOW INCLUDED in the QA table!
Many new and important fields of biology have emerged through recent advancements in life sciences. Vast amounts of knowledge have been generated, as evident from the sprouting of scientific journals catering to niche areas of research. As such, this syllabus refines and updates the content knowledge of the previous syllabus (9744) so that students can keep up to date with knowledge that is relevant for their participation in a technology-driven economy and as a global citizen cognisant of threats of emerging infectious diseases and the impacts of climate change.
For Paper 2 (Structured Questions), the marks has been reduced from 100 marks to 90 marks, while the weightage of 30% remains. (Basically, Paper 2 Questions are now worth more!)
For Paper 3 (Long Structured and Free-response Questions), the marks from Section A (Long Structured Question) has now increased from 50 marks to 55 marks, while marks from Section B (Free Response Questions, aka the essays) has now decreased from 25 marks to 20 marks.
As for the assessment objectives, knowledge with understanding is now more worth at 36 % (from 32 %) than handling, applying and evaluating at 44 % (from 48 %). (In layman terms, this means that the questions are set slightly MORE towards remembering and understanding the content THAN application questions).
Clearer wordings in the learning outcomes (L.O), which includes
Interpret and recognisedrawings, photomicrographs and electron micrographs of the cytoplasm (cytosol) and cellulose cell wall, and outlining their respective functions.
Knowledge of the structure and roles of chloroplast DNA is NOT REQUIRED.
For photosynthesis, with relation to the structure of chloroplast, names of complexes in the ETC and detailed mechanism of action of ATP synthase are NOT REQUIRED.
For Calvin Cycle, knowledge of details of the structure of intermediate compounds and the names of other enzymes is NOT REQUIRED.
For glycolysis, names of enzymes is NOT REQUIRED.
For oxidative phosphorylation, detailed mechanism of action of ATP synthase and calculation of total yield of ATP from oxidative phosphorylation are NOT REQUIRED.
“Type of substrate” is no longer needed to investigate the effect of respiration, however, it has been worded to “oxygen concentration” instead.
For the explanation of effects of climate change as a result of greenhouse gas emissions, “heat waves“, “heavy rains” and “death of coral reefs” are no longer needed. Instead, explanations involving “increase in frequency of extreme weather events“, “stress to coral reef, seagrass and mangrove ecosystems” are now needed.
Worded “discuss the consequences to the global food supply…” to “discuss the consequences to the sustainable food supply…”
Linking of LOs of “explain how temperature changes impact insects” into the “life cycle of Aedes aegypti“, with emphasising on how temperature affects Aedes aegypti‘s life cycle.
NEW L.Os include:
Discuss the bioethics of genetic maternal screening for mutations, including trisomy-21.
For Biological Evolution, explain the Hardy–Weinberg model and the conditions/assumptions it operates in.
Calculate the frequencies of alleles, genotypes and phenotypes in a population for a gene with two alleles, using the Hardy–Weinberg equation.
For Infectious Diseases, outline the terms (i) outbreak, (ii) epidemic, and (iii) pandemic, that are used to describe the spread of an infectious disease such as influenza.
For Impact of Climate Change on Animals and Plants , explainhow mangrove ecosystems help to mitigate the impacts of climate change.
Explain the relative differences between the carbon footprints of a range of anthropogenic activities, including deforestation, energy production (including fossil fuels, hydroelectric power, nuclear power, solar power, wind power and bioethanol) and food production (animal- and plant-based)
9477 candidates NO LONGERneed to:
Describe molecular structure of G-protein linked receptor and explaining how its structure of each protein relates to the its function.
Discuss ethical implications of the application of stem cells in research and medical applications and how human induced pluripotent stem cells (iPSCs) overcome some of these issues.
Describe how the genomes of viruses are inherited through outlining the reproductive cycles ofbacteriophages that reproduce via a lytic cycle only, including T4 phage.
Explain how gene expression in prokaryotes can be regulated, through the concept of simple operons (including lac and trp operons), including the role of regulatory genes, and distinguish between inducible and repressible systems. (Yes, half of OCPG is no longer needed!)
Explain the term: incomplete dominance and applying it in genetic diagrams to solve problems involving dihybrid test crosses.
Using the example “how temperature affects fur colour of Himalayan rabbits” to explain how the environment may affect the phenotype.
Explain how climate change affects plant distribution(vertical and latitude) and plant adaptations, including morphology and physiology.
Development of viral dengue disease in humans, including host-pathogen interactions, human susceptibility to the virus, pathogen virulence, transmission and drug resistance.
Discuss how climate change affects the rich biodiversity of the tropics, including the potential loss of this rich reservoir for biomedicines and genetic diversity for food.
