everyone is welcome
my contact number is 03*********
i will post all the books of physics(paper 1 and 2) soon
plz remember physics is a lengthy subject
whatever you do plz do it comprehensively
(in my opinion) do not go for all the course if u think(by consulting past papers) that you can attempt 5 to 6 questions in the paper then left other topics(but should do them from objective point of view)
its all about how smart you could work

Applied/pure maths are the most difficult subjects in CSS in my opinion
but nothing is impossible
its all about your hard work and belief
after consulting the syllabus if u think you can do it you should go for it
as far as papers are concerned Applied maths papers are difficult right now as compared to physics
this time physics paper was a gift from FPSC to the candidates
but maths was a little bit tough as he asked 4 proof which have never been asked but for maths you should not left any thing(question, examples,proofs)
to score good marks such as 130 to 150
i will post the books of maths as well
if you have physics and maths as optional you should work hard as much as you can because the level of tension and the level of preparation required from you is not comparable with the other candidates physics and maths are different game to play
you are gambling but look at the brighter side if u score 130 in each subject you must have upper hand on other candidates inmy opinion go for it if u can
