I'm not a 12grader too but i wish someone told me not to waste my time on the last chapters of 12thgrade physics

I am not 12th grader too, but I did score 569 when I took the exam 2 years ago. Every chapter is covered in the questions. But the number of questions depend on the extent of the chapter. My Advise to you is, study them from cover to cover (11 & 12 lay bedenb ketemark/sh), other wise it is good to focus on the kelal subjects.

I'm not a 12th grader, but I I did score 550+ back when I took that exam. My advice to you would be to focus on Civics, Biology, Aptitude and Chemistry as anyone is likely to score the highest in these subjects. Math and Physics are usually unpredictable, so make sure you have the rest locked down before you start focusing on them. Good luck.
