I understand, and honestly speaking, JEE Mains is more of a Strategy than Hardwork. You need to have a very effective test taking strategy. Let me tell you what I did during my JEE Examination back in 2019, which ultimately resulted to be successful.

Chemistry is one of the easy to moderate sections in JEE Main usually, across most sessions/papers. Try to complete Chemistry in the first 35-45 mins accurately.

Once youre done, give the next 80 Minutes for Mathematics or Physics, in whichever subject youre very strong and can easily score good giving some time. I was Good in Mathematics, but needed atleast 80 mins to secure a Good Score, in my time which was 80+/120.

Next, I believe youll be left with around 50-60 mins, give that for Physics.
