Engineering Entrance Exam

You don’t have any chance if you are from general category. Your estimated rank will be around 1-2 lakh.

Your rank will be nearby 150000 or more.

JEE rank and cutoff marks change every year. According to the last year’s cut off if you score 85-95 marks in JEE Mains exam then your rank may be nearly 100000 or below or above and your eligibility to appear for JEE advance is according to this year’s cutoff.

I think if you really want to get IIT, you should drop a year as you failed to qualify the JEE Mains exam. A drop year for JEE is risky as the chances to clear IIT are 50% only.
So be ready if you really want IIT.
Best of luck.
