I got 92 percentile in maths around 78 something in physics and 42 percentile in chem which was the only sub I read for 2 years I got 11 wrong ques in chem Can I still get 94% I am already studying like 6-8 hrs daily and will increase this even more just need someone's guidance or plan I just need 94 percentile in april attempt
