how can i do my best in jee 2022 and my target is to score 95+ percentile and my percentile in 2021 was 74

Firstly dear, Warm greetings for the percentile your secured in your first attempt. Now I hope you also believe that JEE Mains and Advanced are two most important exams of your life. For this, you need to solve as many MCQs as you can. Find your area of strength among Physics, Chemistry and Mathematics and plan to attempt as many questions as you can from there. Like every year the Physics portion remains a bit difficult compared to others but you need to solve previous years papers to get profound idea regarding expected physics questions. Think of a genuine cut-off and unless the paper is easy, the cut off is going to rise more in upcoming years. Have faith on yourself, work hard and 95 percentile is all yours

Good luck!!
