In that sense, a number of schools do sort by question types,
especially for Maths.
For Physics, some schools do. However, I don't think any school
really go in depth into explaining how certain graphs in Physics
come about. It's not simply the curves you learned in A Maths
(although similar), but a combination of that and that
understanding of vectors (the plus and minus).
And you will need a strong foundation in basic trigo, a skill
that is tested in the different H2 Maths topics as well, but not
tested as an official topic.
Revision packages are not necessary for you yet. School
tutorials will be good for now as most schools should minimally
arrange questions according to the syllabus guidelines by
MOE.
But do take note that for Physics, I notice that questions
requiring interpretation of graphs are typically tested more in A
Level itself than actual prelim/practice/revision papers.
JC Physics is very interesting. But please do not ever miss any
of your school's lessons. Or if you fall behind, you will have to
catch up. I don't know about other subjects, but for JC Physics,
the topics are inter-linked. Miss a lecture in school, and you will
be lost.
Just imagine a metal chain representing JC Physics, each topic
is the ring on the chain. If a ring breaks, the chain fails to
work. Same for Physics, if you are weak at one topic, you will be
even more lost in topics later on.
Hope I didn't scare you off :)
