Hello Anjali

It depends upon your previous preparation. I mean how much you have studied in your 11th and 12th. If you have studied nothing and wish to start from the Scratch then add 365 days with your 15 days.

But if you are asking about the revision then yes you can just give 4 days to each subject and next 2 days for full revision. Last day rest.

To prepare for JEE Mains in 15 days, it's important that you have devoted sufficient hours at the beginning of the session . But if you want to boost up your preparation, then first revise all the stuffs as soon as possible . Then start practicing previous year question paper. This is very important that you practice sufficient . It would help to build problem solving skills as well as time management skills.  This is very important to crack JEE Mains .

Dear aspirant,

Short answer, you can't. JEE main is a very e competitive exam and have a syllabus that is to use to be completed in a matter of 15 days. You simply cannot complete the syllabus in 15 days and expect to get a good marks in the main exam. the minimum amount of period required to clear the exam is about four months and to get a good rank is anywhere between 10 to 12 months with the average of 3 to 4 hours study per day. So it is not possible for you to clear the exam in 15 days and I must suggest you take a drop year and prepare for the main exam for a full year and apply for the 2021 exam.

The best you can do in the remaining period is download some previous year question paper and try to solve them at Max you could solve 3 to 4 question paper completely that might be helpful to you.

Hope this helps. Thank you.
