Hi
Assuming that you have all your preparation in place there are a few tips you can keep in mind :
- Go for categories/topics/questions where you are strong first.
- Decide early within 25-2- secs whether the question is going to take more time or less. If it takes more time , save it for last.
- Don’t spend too much time deciding.
- Solve mathematics first.
- Use deductive analysis to get the correct option
- Revise complete organic chemistry once more
- Revise modern physics once more

These are some tips that can help you.
