Hi there hope you are doing well.
You can prepare well for April session of JEE main.you have enough time from right now to achieve good marks . prepare well from NCERT textbooks.as you will see questions directly from NCERT textbooks and concepts too .
Try to search for other form too like BITSAT, COMEDK.etc hope this will help you.good luck

Don't get nervous or confused. Don't take pressure. You have another chance for appearing to this exam. You have time now, so start practicing and studying from today, and appear for April Session. The best of two will be considered. If you are eligible to fetch good marks, then you can get admission on the basis of that marks.
The next online application for JEE Main April session shall start from 7 February 2020 and shall remain open till 7 March 2020. The examination will be conducted in CBT mode between 5 April, 7 April to 9 April and 11 April.
