[For Singapore Students taking 2014 GCE O-Level Pure Chemistry Exam; Subject Code: 5073]
How do i put it? Besides getting our students to study very hard on ALL topics, i must say that we were pretty lucky this year. In the last 2 weeks of revision, we went through a couple of concepts which came out almost exact in Paper 2 (Written) on Tuesday 28th Oct 2014 and are worth lots of marks, namely:
- Titration Curves which appear in 4 pages of Paper 2
- Multiple-Step reactions involving Dibasic Acid e.g. H3po4 + NaOH
In terms of topics, let’s take a look at what have been heavily tested in Paper 2 (Written Paper) according to our own students as well as comments that we gather from facebook/twitter/blogs:
- Experimental Chemistry (not tested in Paper 2)
- Methods of Purification & Separation (not tested in Paper 2)
- Identification of Ions and Gases a.k.a. Qualitative Analysis (not tested in Paper 2)
- Kinetic Particle Theory (not tested in Paper 2)
- Atomic Structure (not tested in Paper 2)
- Chemical Bonding and Structure of Matter (about 3 – 4 marks in Paper 2)
- Formulae, Stoichiometry and the Mole Concept (about 4 marks in Paper 2)
- Electrolysis (one whole question in Paper 2)
- Energy from Chemicals (a few marks in Paper 2)
- Speed of Reaction (about 2 marks in Paper 2)
- Redox (about 2 marks in Paper 2)
- Acids and Bases (about 2 marks in Paper 2)
- Preparation of Salts (not tested in Paper 2)
- Ammonia (about 2 marks in Paper 2)
- The Periodic Table and Group Trends (one whole Data Bank Question in Paper 2)
- Metals and Reactivity Series (about 2 marks in Paper 2)
- Air and the Atmosphere (not tested in Paper 2)
- Organic Chemistry: Fuels, Alkanes, Alkenes, Alcohols and Carboxylic Acids (lots of marks in many questions in Paper 2)
- Organic Chemistry: Macromolecules (few marks being tested in Paper 2)
Based on what have been tested in Paper 2 (Written), we are looking forward to the following concepts to be tested in Paper 1 (MCQ) on 11th Nov 2014:
- Experimental Chemistry
- Methods of Purification & Separation
- Identification of Ions and Gases a.k.a. Qualitative Analysis (lots of marks)
- Kinetic Particle Theory
- Atomic Structure
- Preparation of Salts (lots of marks)
- Speed of Reaction
- The Periodic Table and Group Trends (lots of marks)
- Metals and Reactivity Series (lots of marks)
- Air and the Atmosphere (lots of marks)
Now, let us be even more strategic.
Paper 1 consists of 40 multiple-choice questions (total of 40 marks) and the weightage is a WHOPPING 30%, in case you are not aware of it. Doing well in Paper 1 will definitely bump up your overall Chemistry grade. In view that Paper 1 is only for 1 hour, you must not waste time. In fact you have an average of 1.5 minutes for each question.
If you are a student taking your GCE O-Level Pure Chemistry (syllabus code: 5073) and would like a final dash to score 40/40 marks, i welcome you to join us in our annual Score 100% MCQ Workshop on 8 Nov 2014.
All the best for the final Chemistry paper. See you at the finishing line.
