How to tackle organic chemistry Organic Chemistry occupies a distinctive and important position in the Singapore Chemistry syllabus. You may also like to explore isomerism in transition metal chemistry in the Zumdahl textbook, which is in university chemistry syllabus but may appear in prelim papers. Many JC teachers have taken materials from university organic chemistry textbooks and setting new reactions in the prelim papers beyond the scope of H2 and H3 syllabuses. Please pay close attention to organic chemistry topics, as this section is highly important. When you are ready for the challenge, you may want to reproduce summarised reaction charts (with reagents and reaction conditions) by functional groups of all reactions in organic chemistry. A lot of the concepts in biochemistry are drawn from the foundational principles of organic chemistry. Arrow pushing mechanism in organic chemistry You may like to ask your tutor to teach you arrow pushing mechanisms in organic chemistry. 

There is an organic chemistry textbook that is published in 2012 that is written by 3 authors, one of whom is a Cambridge University author. Organic chemistry You may like to study on chirality - meso and diastereomers molecules. The examiners are gonna set some NUS/NTU year 1/2 questions in this year's Cambridge papers. Be prepared for uncertainties in the chem exams!! Organic Chemistry questions are highly likely to take up more than 50% of your prelim exam papers. Physical chem questions maybe occupy about 30%. The examiners favor structural elucidation problems in organic chemistry. Also, if your class is game for challenge, ask your teacher, if appropriate, to teach your class some H3 / old syllabus S paper / university 1st year organic chemistry. Cambridge is literally operating without a syllabus nowadays. I noticed that since 2010 exams, examiners have been using university organic chemical reactions in papers. If the examiner continues the same trend, organic chemistry is going to be atypical this year. So an examiner may take a recent university organic chemistry textbook or his own research interests, then finds some functional groups not in A level syllabus. Tartaric acid came out in 2013 Cambridge papers and he was spot-on. So you may want to study Chemical kinetics - enzymes and also proteins in organic chemistry. A question really came out in 2014 exam papers. 

There is an old nostalgic examiner who set one of the questions of Paper 2 of Cambridge exams last year. a level chemistry tuition is available. Some topics to take note of You may like to revise chemical bonding (a tricky topic), energetics (an important topic) and organic chemistry if you school has started on organic chem. School examiners and Cambridge examiners may like to set questions on this section. International Cambridge exam papers International Cambridge 2013 exam papers are out in xtremepapers.com You may like to scan through the papers and analyse the trends that the examiners are laying out. The Cambridge Pre-U papers are also out, and are tougher than the traditional Cambridge International papers. Your papers will be more difficult than International Cambridge. If you have the time, you may want to practise the latest International Cambridge chemistry papers at xtremepapers.com , just in case Cambridge sets similar questions from that paper. BedokFunland JC tutor has claimed that Cambridge modified some of the International chem papers. Talk about dangerous chemistry. SPA planning on organic chemistry Exam revision Maybe you like to do the Cambridge exam.
