I am assuming that your basics are clear that's why you have asked for preparing in 2 months. If not, then the topic you have chosen for studying, clear the basic part first then move to the next aforementioned step.
Start preparing today onwards. You can score well in these 2 months also if you can add smart work to hard work.
All the best
Hope this helps
Make a proper timetable that you follow each day. By timetable, I don't want you to plan for coming 7-10 days,etc anything ... Understand the fact that everyday is going to be different. So get up in the morning and then as per your mood, decide the days target and achieve it. Achieving and winning each day is very important if you want to win the big competition of cracking JEE. Try to revise things more rather than studying and solving new new things. Avoid all the distractions, and try to study more and more as much as you can.
Best wishes. Thank-you.
