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 (if you can’t find the labs you need, Whatapps us at 88765498).http://wa.link/w0xxk2
(2) Whatsapp or Message our staff at 88765498 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 $50 via Paynow or funds transfer.
(5) Make the required payment for each lab session at least 7 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 slot)
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.
Based on the above syllabus, we have selected several lab topics which students need to complete to achieve the above practical exam objectives.
Note: For training purposes, Pure and Combined Science students attend the same practical sessions as the syllabus for practicals is the same for both. The only difference between the two kinds of practicals is there are no Planning questions for Combined Science students.
