SPM Trial Paper 3 Analysis

How do u guys feel at the moment?? Hope u are ready for this challenging week... especially about your final preparation on having physics after add maths paper. Just be calm & keep your concentration at highest level after u 've finished add maths paper.
Make sure u change your calculator angle mode from radian to degree mode. Otherwise your calculation on topics like refractive index,critical angle, resolving forces angle will be wrong. Dont forget to bring protractor, who knows this time they might ask u to draw triangle of forces in equilibrium with proper scaling.

Here i managed to list out some analysis on paper 3 section B based on recent states' trial papers. Hope this information will be useful.

Anyway i wish all of u Good Luck and all the best in your physics & other papers.

Which experiment will come out for physics section B,paper 3?

Here are some tips on which type of experiment always being asked in section B.
Some students said there are too many experiment to study. Yeah it is so true, thats why some students are gambling to study form 5 experiment only. There are pro & cons if u try to do this approach. The advantage is.. form 5 experiment is much lesser than form 4 experiment. Usually in SPM, chapter like Electricity, Electromagnet & Waves are the favorate to be asked in exam. But if u analyse past years paper, experiment on electromagnet has been asked for the past 2 years..so i would say this year, experiment on electricity & wave can be the favorate. But sometimes the unpredictable can happen..who knows Electronic or electromgnet experiment can be asked again this year ;)

There are some disadvantages if u are only relying on form 5 experiment. For example in 2008, the experiment on form 5 is a bit difficult. Student hardly state its inference & hypothesis correctly. If u do the wrong hypothesis, u have the chance to loose all the 12 marks. I would say majority of students on that year chose to answer form 4 experiment. For me whether u want to gamble on form5 experiment or not is very much dependent on your level of understanding on all the chapters.

Through my observation,what ever experiment came out last year, it wont be asked again this year. So for form 4 experiment, u can close one eye on Hooke's law. Thats y if u notice, in the states trial paper, u hardly see any hooke's law's experiment being asked. However u have more than 10 other form4 's experiment to be studied. Out of these , only 1 will come out..to be frank,its hard to single out which one will be asked i SPM... all i can do is to guide my students.

Basically i would categorise two important type of experiment that need to be studied:
1. Experiment on physic's law..e.g gases law, etc
2. Experiment on physics' formula..e.g P=hpg ( came out in KL trial), 1/f =1/u+1/v (light)

As i said, in last year Hooke's law experiment came out,..while in 2008 experiment on pressure which based on formula P=F/A had been asked.
NOW U SHOULD ASK YOURSELF..How many experiment on physic's law & physics formula do we have in physics syllabus? On top of that, how many have u covered???
If u type of last minute student..just attempt all paper 3 in the last trial..if u lucky enough, one of them will come out..but i dont guarantee it ok!
Now its time for u to do yor work.....
