• Since you are good at Maths, start doing it in a much better way. Prepare in such a way that, you could attempt almost every question in Maths section. This boosts up your confidence and helps you in doing the other sections well. Try to attempt the Maths section, whatever might be the order of your Question paper. Set the boundaries for time to each subject. Spend more time on the subject you know well ,so that you could make best of it! All the things mentioned above holds good for JEE Main because, there are no subject wise cut-off marks unlike JEE Advanced.
• Or else, decrease the time you allot for Maths and focus on the other subjects. If you find exams coming very soon, then read the basic concepts in Chemistry and revise the topics which were you good at. Since all the questions from Chemistry are not tough, you can attempt the easy questions and questions which are from a topic/chapter that is well known to you. This gives you a feeling that didn’t neglect any subject.

Important Note:

Don’t rely more on your Weekend tests/ Daily assignments. They do play a vital role in improving your skills but, they shouldn’t let you down. How you think and tackle a problem in a exam at that time matters!! Stay relaxed and never panic in exam. Don’t leave the topics which you were good at. Try to reduce the negatives as much as possible!

All the best! :)
