2014 GCE O-Level Chemistry 5073 – Paper 2 Post Mortem

[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.

Quick Announcement:

I’m conducting my annual event : Organic Chemistry Mastery Workshop on 31 July, 7 & 14 Aug 2010 (830 am – 1230 pm) to help students (Pure Chemistry or Combine Science) to

Understand this easy-to-score major Chemistry topic step-by-step (which many schools rush through)
Link up the various chapters & Identify the inter-relationship for effective understanding of the concepts
Be able to apply concepts on real exam questions to earn additional of 20+ marks in ‘O’ Levels
Expose themselves to the variety of possible Organic Chemistry questions which can be asked
Avoid common mistakes in Organic Chemistry

This workshop is for students:

Who haven’t been doing well in Chemistry all along and want to improve themselves in the remaining 15 weeks. It’s possible since Organic Chemistry is an independent topic from the rest of Chemistry.
Who wants an overall revision just before their prelims & ‘O’ Levels, focusing on the essential concepts in Organic Chemistry.

Chemistry Tips: How to Revise for your GCE ‘O’ Level Chemistry Exams

Update: For 2018 O-Level Pure Chemistry students, please read the latest post at https://www.simplechemconcepts.com/tips-for-o-level-pure-chemistry-paper-2-written-exam-2018/

In about 2 weeks time, Singapore Students will be taking their GCE ‘O’ Level Examinations.

Many of you are also having your ‘study week’ where school lessons has finally ended and you are given the time (2 weeks) to sit down and thoroughly revise through your notes, books, and previous test/exam papers.

For GCE ‘O’ Level Chemistry Exams, you need to know the essential concepts well in order to score the marks you desire. Only about 15% of the exams will be based solely on memorising skills, etc. As such, it is important to know the topics well.

Furthermore, you will be seeing questions in Paper 2 (Written) where one question will be split into many other parts – and each part will test you on a certain concepts i.e. several topics will be tested in one question.

Previously, i have blog before on tips for revising for GCE ‘O’ Level Chemistry Examinations, and you can find them through the links below: [Read more…] about Chemistry Tips: How to Revise for your GCE ‘O’ Level Chemistry Exams

Secrets: Why you need to master Organic Chemistry in GCE O Levels?

Hi students,

As mentioned in my previous blogpost, Organic Chemistry is of extreme importance in GCE ‘O’ Levels Chemistry Exams, due to 2 main reasons (based on my analysis of Past Years Exam Papers):

High weightage about 18 – 25 marks (15 – 21%) of your written O Level Chemistry Exams
In Year 2008 O Level Chem Exams, the last Question (Either/Or Question worth 10marks) in Paper 2 are both Organic Chemistry. This means there is no way you can escape Organic Chemistry

Need MORE reasons (that i observed last 3-4 years) why you need to MASTER Organic Chemistry????

1) Organic Chemistry is an independent component that you can master on its own, regardless of how you have fared for other previous chapters

2) Organic Chemistry is in fact VERY EASY – all the 5 chapters/topics in Organic Chemistry are inter-linked and once you master 1 topic, you will be able to master the other topics, with ease once you have the correct methodology

3) Contrary to many students believed that Organic Chemistry needs lots of memorisation, Organic Chemistry DOES NOT need lots of memory work. You just need to associate it to our everyday life and be clear of how each topics are interlinked with each other – and you will score well for it!

4) Majority ALL schools in Singapore (Both GCE O Levels and IGCSE/IB) rushed through Organic Chemistry chapters in June / July in order to finish the syllabus and welcome the School Prelims Exams. Many of the teachers only glanced through it with their students (“surface learning”) in order to finish the syllabus. There are even 1-2 schools (my students are in these schools) that actually asked them to READ ON THEIR OWN!!!! Gosh! You can’t learn Organic Chemistry just by reading textbook? cos concepts are required.

If you are of these students that aim to do well for your GCE ‘O’ Levels Chemistry Exams, i urge you to master Organic Chemistry. Spend time mastering it, please.

If you are facing the following problems in mastering Organic Chemistry, do check out the Early Bird Registration (by 15th July 2009) for our annual O Levels Organic Chemistry Mastery Workshop 2009

I will see you at the workshop! =)
