Hello aspirant......

To crack jee mains in 21 days is not any easy job

First select all the easy topics in all the three subjects and then revise all the formula's in the maths, physics and chemistry

Solve mock tests and also try to solve minimum 150-200 mcqs daily and have a look on the previous year's paper it helps you a lot

I hope this information is helpful

All the best.

Hello dear aspirant,

21 day is very short time for preparation of jee mains which has a very vast syllabus.
The best you can do in these 21 days for cracking jee mains is that you should target easiest of the topics of all three subjects.
In maths you can target statistics, mathematical reasoning, set, relations etc
In physics you can target kinematics,laws of motion and other topics that you find easier of the lot
In chemistry target polymers, environmental chemistry, atomic structure and other easier topics.
Try to as much of the last few year question paper as you can.
Doing all this might help to get to the cutoff marks

Hope this helps

Dear Aspirant,
JEE main is a national level engineering entrance examination.Approx 10 lac students compete with each other.So, you can pass the cutoff marks if your 12th standard basics are clear and you are able to do the numerical problems.For better results you can through the previous year papers of each subject and practice it in the given time.  It will be a much better option.You can check the previous years cutoff trends.
