Few Last Minute Tips:
1.Remember there is no sectional cutoff so devote time where you can score.
2. Maximise the total score.
3. Past experiences suggests that Chemistry is the easiest to score. So if you are good in it try to get 100 + score in chemistry.
4. Try to identify and leave very tough or bouncers in the paper. JEE MAIN always has 2-3 such questions in Physics section specifically. Don't get disturb from them. Concentrate on your scoring areas.
