O-LEVEL CHEMISTRY PRACTICAL - SINGAPORE LEARNER

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.

*Enjoy huge discounts on fees if your lab sessions start in January! Send a message to 88765498 for details.

MOE/SEAB SYLLABUS FOR O-LEVEL CHEMISTRY PRACTICAL

Paper 3 (Practical) is weighted to 20% of the assessment.

Candidates are expected to have been exposed to a range of topics and experimental techniques such as:

Titration, e.g. acid-base titration (with suitable indicators such as methyl orange, screened methyl orange, and thymolphthalein). Other types of titrations may also be required, and where appropriate, sufficient working details will be given.
Speeds of reaction that may involve measuring of quantities, e.g. temperature, volume, length, mass or time measurements
Experiments involving separation techniques such as simple paper chromatography, filtration and distillation
Salt preparation
Gas collection
Qualitative inorganic analysis involving an element, a compound or a mixture, including displacement
reactions and tests for oxidising and reducing agents. Candidates should be familiar with the reactions
of cations, reactions of anions and tests for gases as detailed in the Notes for Qualitative Analysis. Candidates would not be required to carry out tests involving Pb2+ ions or sulfur dioxide gas.
Reactions involving ions not included in the Notes for Qualitative Analysis may be tested: in such cases, candidates will not be expected to identify the ions but only to draw conclusions of a general nature.
Candidates should not attempt tests, other than those specified, on substances, except when it is appropriate to test for a gas.
Qualitative organic analysis requiring a knowledge of simple organic reactions as outlined in Section VI, e.g. test-tube reactions indicating the presence of unsaturation (C=C) may be set, but this would be for the testing of observation skills and drawing general conclusions only.

OUR STRUCTURED PRACTICAL TRAINING SYSTEM

Based on the above syllabus, we have several structured programs for you, depending on whether you are a private or school candidate.

PRIVATE CANDIDATES

If you are a private candidate, for each subject, you must complete 4 Basic practicals (preferably by 15 Apr) plus a further 2 Exam-Paper-Style practicals, before we issue you a certificate to acknowledge that you have completed a sufficient amount of practical training necessary for your actual exam. Beyond these 6 practical sessions, you may also opt to attend our Practical Crash Courses and our Practical Mock Exams in June, September or October.

SCHOOL CANDIDATES

If you are a current school candidate, you may select any of the training labs found in our schedule, and you are strongly encouraged to sign up early for our Practical Crash Courses and our Practical Mock Exams which will be held in June, September or October.

OUR CHEMISTRY PRACTICAL SCHEDULE (Jan to Oct)

*Other labs, such as PC10 – PC16, are also available for those who want further training or as mock exams.

Practical Days: All days except Monday.

Practical Timings:

Tue & Wed: 10.30am-12.30pm | 2pm-4pm | 6pm-8pm (or later upon request)

Thu: 10.30am-12.30pm | 2pm-4pm

Fri: 10.30am-12.30pm | 2.30pm-4.30pm | 6pm-8pm (or later upon request)

Sat: 10.30am-12.30pm | 2pm-4pm | 6pm-8pm (or later upon request)

Sun: 12pm-2pm | 3pm-5pm | 6pm-8pm (or later upon request)

IMPORTANT POINTS TO NOTE:

The above is the ideal schedule for students who want to excel in their CHEMISTRY practical exams, by starting in Jan and having a final practical revision or mock exam in Oct. The practical sessions are well spread out, giving students time to study the theory components as well as other subjects. Thus it is highly recommended that you commence your practical training in January.
