Note:

The above is based on my analysis of the Physics Paper 2 from 2008 to 2012. In general, Paper 2 topics of the previous year is not repeated in the following year, and topics that have not been tested for several years are more likely to be tested this time round.

Please not that the above are just guidelines and not 100% accurate. The topics that I have de-emphasized for Paper 2 can still be tested in Paper 1.

Mixed feelings during relief teaching

I’m now in the staff room of a school in the north, during a break in relief teaching for the day, to cover the work of a Physics teacher. I still enjoy teaching in schools, seeing students clowning about and teachers cracking jokes now and then, and of course, the free parking.

But it saddens me when, at the end of a lesson, the students ask me if i’m coming back to teach them again, or if I can replace their regular teacher. It’s not that I’m such an outstanding teacher; I just do what I thought all teachers should do in class, such as giving real life examples, doing demonstrations, injecting humour now and then, and finally drawing their attention to what the examiners would always look out for in their answer papers.

It has happened just too many times, this thing about students asking me whether I can be their classroom teacher for the long term, that I’m beginning to wonder how many teachers in service are actually passionate about their jobs and possess the right mixture of attributes that can capture students’ attention and make them think about what they are learning. Sometimes, even my own tuition students ask me to teach in their schools.

I’m happy to know that I have the right teaching techniques and the personality to connect with students. But I can be sad thinking about how many students out there are wishing that they have a different teacher for whatever they are learning right now. I’m sure there is a sizeable number of good teachers out there, but perhaps it’s still not enough for the around 30 000 students in every cohort.

Just because you are highly educated in a certain field, it does not mean that you are able to transfer that knowledge to others. So to aspiring teachers out there, please do not enter teaching because (1) it is a stable job, or (2) it gives you many holidays, or (3) you think it is an easy job, or (4) you want free parking, or (5) a job near your home, or (6) you want cheap food. Of course, nothing wrong with all these perks(I myself enjoyed most of these for 3 years), but you should make sure that you possess the right mixture of knowledge, temperament and communication skills for the job. Teachers are the most powerful people on earth; they have influenced leaders like Obama and even Hitler, and others you have not yet come under.

Do not drop a subject if you still have interest in it.

This is the time of the year when your school may ask you to drop certain subjects that you are weak in, using the lame excuse that even if you work hard, you will at most obtain a B4 or a C5. In reality, your school is more concerned about its own academic reputation, not about you. Schools are worried that if weak students continue to sit for certain exams, their national exam results (percentage passes or distinctions) will worsen. Yes, it’s not about you or your future; it’s about the school’s image.

Thus you must be wary when any of your school teachers call you in to give you hints to drop a subject. The teacher will say that if you drop one subject, you will have more time to study for the other subjects. While this may be true, what about the months that you have spent learning that subject? And the extra hours that you create by dropping a subject, will it all go into learning the other subjects? Having less subjects also mean that you will be taking a bigger risk should the unexpected happen to your remaining subjects, as you would be relying on a narrower band of subjects.

Two subjects that schools like to ask students to drop are Physics and Additional Math, the two most conceptually difficult subjects to master, in my opinion. So should you drop any of these subjects if you are asked to?

For Physics, the answer depends on whether you still like learning about Physics. If you still do, then continue doing it and take the exam, even if you have hardly ever passed Physics before. Why? The reason is, Physics has always been a difficult subject for most people. Thus the minimum mark to obtain the A1 grade for Physics may still be in the 75 to 79 range, significantly below that for Math (which is probably around 88 to 91). Hence you still stand a good chance of getting a B3 or above for Physics if you are willing to spend enough time practising Physics questions. This is only possible if you don’t mind studying Physics.

I have a tuition student who is very weak in Physics, and true enough, his teacher has been pestering him to drop Physics. So his mum turned to me for advice. Since he still likes Physics, I told the mum not to give in to the teacher. The boy finally passed Physics for his recent SA1 exam, and is now doing exam papers to get a better grade for his upcoming Prelim exam. The boy is mentally slow, but since he likes Physics, the school should have helped him improve instead. Isn’t it the purpose of schools to develop each student to his maximum potential?

The boy had also been asked to drop A. Math. But like I’ve said elsewhere, NEVER EVER drop A. Math, as knowledge of it is useful for many future courses such as Business, Engineering or Science. Although he still failed in his SA1 A. Math, he has been making significant progress as he still likes doing Math. Where there is a will there is a way. Let children and young people learn what they want to learn, even if it means getting poor exam results for the short term. A school should not be telling students to stop learning this or that, or to stop making effort, or to give up on something good that they have started.

If you need more advice (or even tuition, see below) on Math, A.Math, Physics or Chemistry or Combined Science, do whatsapp me at 97860411.
