• MCQ - 20 marks (20 compulsory Chemistry MCQ) - 20% of Science grade
• Structured - 30% of Science grade

1. Section A - 14 marks (all compulsory)
2. Section B - 16 marks (3 Questions, Choose 2)

The remaining 50% of the Science grade comes from either Physics or Biology component.
Students only need to sit for 2 papers for Science (Chemistry + Physics or Biology).

Total duration for MCQ paper: 1 h 

• 40 MCQ (20 Chemistry, 20 either Physics or Biology) - 20% of Science grade (only 10% for Chemistry component)

Total duration for Structured paper: 1 h 15 min

• Structured - 32.5% of Science grade

1. Section A - 45 marks (all compulsory)
2. Section B - 20 marks (3 Questions, Choose 2)​

Total duration: 1 h 30 min
30 marks - 15% of Science grade
​Format: 1 or 2 Questions on Chemistry (15 marks) + 1 or 2 Questions on Physics/Biology (15 marks)

1. Energy Changes
2. Speed of Reaction
3. Redox
4. Alcohols
​5. Carboxylic Acids
​6. Qualitative Analysis

Experimental Design
- Know how to design experiment to measure rate of reaction

Identification of Ions and Gases
​- Describe tests for ammonia, chlorine and sulfur dioxide

Mole Calculations
- Formulas 
- Concept of limiting and excess reagent

Alkenes
- Addition polymerisation
- Pollution problems caused by plastics

These topics are exactly the same as those studied by Sec 4 O Level students. However, the questions set for these questions are no longer as simple as those seen in Sec 4 N(A) papers. Students are expected to answer questions which require them to "explain", "describe", "elaborate" or "suggest".

Hi Mdm W, just a quick feedback regarding my observation so far:

1. J is weak in understanding of concepts. She may be able to give the answers to certain questions, but when asked further, she doesn’t know how she formed her answer. Most likely, she uses a lot of memory work when studying, instead of understanding the concepts.

2. She lacks skills when forming equations, taking up a lot of time even when it’s a 1 mark type of question. I have given her tips on how to form equations faster and more accurately. Also taught her how to check the equations formed.

3. She is not very sure of the keywords to use for answering questions. In chemistry, there are certain sentence structure template that we use to answer questions. And most likely she lost marks when she did not answer using important keywords (which she didn’t know that they are keywords). 

4. I went through the basics to make sure that she doesn’t make the same type of mistakes again and again as these basics are repeated throughout all topics. 

5. We started with the most challenging chapter which is electrolysis. She couldn’t answer well even for the most basic type of questions. Have already gone through her mistakes and given her some homework.

6. I stressed to her the importance of understanding of concepts. Knowing how to explain how she came out with the answers is crucial as the exam questions set in recent years require students to answer questions base on new context. Remembering answers from familiar context will give her a disadvantage.

I gave her some reference materials, notes and worksheets. Hopefully she will find them useful. Will be preparing according to her request for the next session.

To win a war, we must first know our enemy well. 

Duration of Paper 1 MCQ: 1 h 
Duration of Paper 2: 1 h 45 min

MCQ: 40 marks (30% of overall grade)
Section A + B: 50 + 30 marks (50% of overall grade)

A copy of the Periodic Table of Elements will be provided.

What can I expect?

MCQ consists of 40 questions from all topics. (Tip: Do the Mole Calculation questions LAST!)

Section A consists of 7-9 compulsory structured questions, each with several parts.

Section B consists of 3 questions.
-The first is a compulsory data-based question and the second is a long compulsory questions.
-The data-based question requires students to interpret, evaluate or solve problems using a set of given data.
-The third has an either/or option. 

Be familiar with the Periodic Table and save time by knowing where the common elements are. 

Create your own personalised Periodic Table. Jot down essential notes and refer to it for all assignments. (All my students will have a copy each from the first session.)

Know exactly what information can be found on the Periodic Table:
-proton/atomic number
-mass/nucleon number
-electronic configuration
-charge of an ion
-relative atomic mass
-group and period number 
-number of electron shells and valence electrons
