You have two options left with you.

You must have given other engineering entrance exams.Wit for the results and counselling for those.

Either drop for one year if you have a chance left and prepare well for next years jee mains and advanced.

First thing to do is, deactivate Facebook account(if any), uninstall whatsapp(if any), break up with your girlfriend(if any), and promise yourself, “ I'll not get distracted by any thing in this one year, be it any girl or be it any other pathetic or beautiful reason”.

# Now, you have to divide your syllabus is parts or call it phases. Let me make it easier for you.

Physics- D.C.Pandey has already done this for you.

Chemistry- 1. Physical chemistry, 2. Organic chemistry, 3. Inorganic chemistry

Maths- 1. Calculus, 2. Coordinate geometry, 3. Algebra and trigonometry.

#. Now you have to start making your own notes, if you already have notes from your classes, or any other student, even then, make your own notes. ( If you already have good notes, then your notes need not to be very detailed, you can make notes of those topics or formulas that are common and mostly used).

#. Plan a routine for yourself. Everyday study in durations of 3 hours and always try to study in between 9 am to 12 am so that your biological clock is set according to the jee timings. By doing this, you can study for 8 to 9 hours daily without feeling any kind of fatigue or laziness. For example, wake up at 6 or 7 do some meditation or yoga. Do all other necessary things, have food, listen to some songs( Arijit Singh will do, but not after break up please). At 9 am sharp start studying a subject(I'll recommend maths). Study till 12, take rest for 1 hour(during that 1 hour you can drink some juice, eat some fruits, or anything light, listen to songs for relaxing yourself). At 1 pm, pick up chemistry NCERT, and start reading chapter, at 1:30, have your lunch. Again start studying from 2 pm(physics). Study till 5 pm. Take a break for 1 hour again,have some light snacks. At 6, start studying chemistry, study for 3 hours again. At 9 have your dinner, and go to sleep around 10 and then repeat.

Benefits of above given schedule- you'll get enough sleep of 8 hours. You'll be able to study all of the 3 subjects. And you can have some light snacks in between which is healthy and a healthy mind lies in a healthy body.

#. Now give yourself a test after every 2 weeks, give that test like actual JEE mains or advance, as you like. And on the day when you'll give test, don't study anything else. Go out, play cricket, do something else recreational. You can have 1 free day after 2 weeks of hardwork. I think that's fine.
