We provide A-Level / H2 and O-Level Physics, Chemistry, Biology and Science (Physics/Chemistry/Biology) Practical training for private / school candidates and homeschoolers, for both local (eg. H2, Singapore-Cambridge) and international exams (CIE, IGCSE). School candidates are also welcome.

CIE SYLLABUS FOR CHEMISTRY PRACTICAL

Paper 3 (Practical) is weighted to 23% of the total CIE AS Level assessment.

One question will be an observational problem in which the candidate will be asked to investigate an unknown substance or substances by specified experiments. The substances may be elements, compounds or mixtures. Candidates will be expected to record their observations, analyse their results and draw appropriate conclusions.

The other question or questions will be quantitative: either volumetric analysis or measurement of a quantity, e.g. the enthalpy change of a reaction, mass change on heating, changing the rate of a reaction or measuring a gas volume. Candidates will be expected to draw suitable tables, graphs and other appropriate means of presenting the data. They will analyse the data, perform calculations and draw appropriate conclusions from them.

One or more of the questions may require candidates to comment on the accuracy of the procedure or identify sources of error and make suggestions for change.

Candidates should be able to:

• set up apparatus

• follow instructions given in the form of written instructions or diagrams

• use their apparatus to collect an appropriate quantity of data or observations, including subtle differences in colour, solubility or quantity of materials

• make measurements using pipettes, burettes, measuring cylinders, thermometers and other common laboratory apparatus.

It will be assumed that candidates will be familiar with the following qualitative analysis reactions

(i) the reactions of the following cations: NH4 + , Mg2+, Al 3+, Ca2+, Cr3+, Mn2+, Fe2+, Fe3+, Cu2+, Zn2+, Ba2+

(ii) the reactions of the following anions: CO3 2–, NO3 – , NO2 – , SO4 2–, SO3 2–, Cl – , Br– , I –

(iii) tests for the following gases: NH3, CO2, Cl 2, H2, O2.

 

In qualitative experiments, precise descriptions and comparisons of colour or other observations are expected. In a titration with a good end-point, candidates are expected to record two titres within 0.10cm3 .

 

You can book (at least 5 days in advance) any of the following slots for your science practical training:

What you will get at each 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.

(3) Notes on important aspects of science practicals.

We will also conduct CIE A-Level Mock Practical Exams in April, May, September and October.

HOW TO BOOK A LAB SESSION:

(1) Decide which Program or Lab sessions you need or most suitable for, by visiting the webpages of the practical subjects you are interested in.

(2) Whatsapp or Message our staff at 87762711 with your Name, Private or School Candidate, A or O level, Subject or Lab Name (e.g Lab PP2), Date and Time of Lab. (Our staff will then guide you on how to register and make payment. If you are not sure about the lab sessions, just state your Name and the Subjects and we will get back to you)

(3) Register Online by clicking below:

(4) Pay Registration fee of $30 via Paynow or funds transfer.

(5) Make the required payment for each lab session at least 5 days before the date of the lab session. (You may also pay for several sessions at one go to ensure that you will have a place in future slots)

FEES PER SESSION

Practical Training Session: $320

Mock Exam:- $380

(The full fee must be paid at least 5 days before the practical session to confirm your attendance as a lot of preparation is needed for practicals coupled with very limited class size. No refund will be given should you fail to turn up.)
