Students who attained success under Mr Peh
What are Mr Peh’s strategies in helping his students ace A Level Physics?
Are you wondering how students have attained success under Mr Peh for A Level Physics?
Continue reading below to find out the various strategies that Mr Peh adopts to help students achieve their desired grades.
1. Highlight commonly made careless mistakes.
Many of the A Level Physics calculation questions are rather straight forward questions. Hence, by the A Levels, most students should be able to solve them already. This means that you need to be vigilant and make sure that you do not make careless mistakes when solving them. Otherwise, you will fall behind other students from your cohort. You will be surprised that some of these careless mistakes are also frequently made by the better students. This includes being careful with the signs especially when solving Projectile Motion and Dynamics questions, look out for the labeling and units of the graphs provided by the question. The following is another example that students often make mistakes in.
2. Link and connect to your prior O level knowledge and Chemistry knowledge.
Some of the A Level Physics concepts can be abstract and difficult to understand, and at times, there may even seem to be a conflict between what you have learnt in Secondary School VS Junior College. For example, gravitational force which is given by W=mg, is now transformed to become F=GMm/r^2, gravitational potential energy which was previously given as mgh, is now transformed to become U=-GMm/r. I think that it is very important to spend substantial amount of time, explaining the rationale behind the differences in the formulas so that you can fully appreciate the concepts better.
Also, many concepts and formulas that you learnt actually overlap with A Level Chemistry concepts. Take Nuclear Physics for example, radioactive decay can be considered an overall first order reaction, that is why you can observe that many similar formulas appearing. Energy released = Total binding energy of products – total binding energy of reactants. This is, in fact, just a simple application of Hess law.
Then in Electrolysis, you have learnt Gibbs Free Energy is given by nFEcell. This can also be linked to the formula that you have learnt in Current and Electricity: Work done, W=VQ
Unfortunately, many Junior College lecturers and tutors may not be able to help in making these links explicitly for you, either due to lack of time or being out of touch with the O Level Physics and A Level Chemistry Syllabus.
3. Concise summary notes and topical practice questions including MCQs and Structured Questions are provided.
For A Level Physics, practice is of paramount importance to ensure that you are well prepared for the exam questions since most of them require your problem solving skills. In particular, drawing free body diagrams, applying Principle of conservation of energy and momentum, using the ratio method are skills which are required across the entire A Level Physics syllabus. Thus, by doing the practice questions in your school tutorial, revision packages as well as the topical questions which I have sourced from past year prelims will ensure that you become more ready and prepared for the examinations.
A Level Solutions
I have written answer keys for some of the recent A Level Physics Papers . This is because I not only want my students to know the answers to the questions, but also the thinking process behind them, pitfalls and common misconceptions to avoid. The exact same question is unlikely to be repeated in the A Level exams but you will likely require the same thinking processes to tackle questions from the same topic.
I would also want to identify the difficult questions for my students, so that you can place these aside first, focus on those manageable questions but yet you are having difficulties. After that, then you go back to these difficult questions and try them again. Remember that it is important to be exam smart, you do not need 100% to get your ‘A’ grade. However, you must be able to do the questions that an average student should be able to do, and maximise your marks there.
