Hi Mayank,  This can be possible. You can repeat 11 th and 12 th and also apply for jee main and advance. For both the exams new 12 th result will be consider.

Thanks.

Hello Mayank!

Repeating 11th and 12th will be okay but you may be not eligible for JEE ADVANCED by then as you will take 2 more years for 11th and 12th again.

It will be okay if you appear in improvement exam as it is very much valid for both JEE MAIN & JEE ADVANCED. You can utilize one entire year and do things well. Do remember that JEE ADVANCED only allows 2 attempts whereas JEE MAINS allows 3.

Hope that helps!
