I didn't study for jee 2021( my first attempt) is I give jee 2021 or wait for jee 2022 and jee 2023 jee2024

Hi
Even if you are lacking preparation for the jee mains  I would advice you to attempt the January exam and try and get a fair idea of the format, complexity of the exam and an aura and stress of giving such an exam. These are a little skills that you need to master and be aware except for the preparations that go into it.
Nta allows you to have 4 attempts at this exam (2 every corresponding years). Hence even if you don't clear this attempt you would be left with 3 more attempts(one in April and the rest two in 2022).
Jee mains is a boards level examination and if you prepare well for your boards you are likely to get a good score in jee as well.
Dropping an year and extending your prep time increases stress and usually reduces your chances of clearing the exam ,hence apply this year and prepare hard.
Good luck

Dear student,

If you are still currently studying in class 12th and you have not given your class 12th boards exams yet, and you will give jee mains next year, then you will be left with only 2 attempts that is - JEE mains 2022 and JEE mains 2023.
And you can not give jee mains 2024.
Because in JEE mains you can give maximum up to three attempts, counting from your class 12th passing year.

But if you haven't prepared for jee mains then still you must give jee mains 2021, as you will get to know the examination in real.
There are still some months left for jee mains, so prepare in these left months for jee mains as the best as you can.
And in 2021 give your first attempt of Jee mains.
If you will not get good ranks then you can opt for a drop and one again prepare with full confidence for jee mains 2022. But never leave any attempt.
Try to give your first attempt with full positivity.

Also you can prepare in these left months for JEE mains with our JEE mains complete Knock Out package, so that you can still prepare for jee mains 2021 within the direct expertise guidance of our experts and a complete exhaustive online coaching.

Hello kid,
.
As you know JEE examination should be given for 3 executive year from the year of passing. So just give a try for 2021 even if you don't get passed you will get an idea how the examination will be. Prepare till the examination date, you have more time for preparation as you are from maths background it will be easier to prepare or join nearby classes
