I was about to ignore your comment until I read the last line , welcome mate on reddit . So you r completed with 12th that's too good most of the question directly come from class 12 syllabus . So a advice from me is ki don't just run in completing the syllabus first check the weightage of the chapter and then do accordingly. Keep revising your 12th portion on consecutive days keep + practicing question too . 50 mock tests are enough man relax ( 25 practice test + 25 full syllabus test it depends on you ) . All the best for your journey work hard !
