Hey student.

As you have mentioned your percentile in Jee mains paper 1 in session 1st is 51.61 . So, following this, you can expect that your rank might be nearly ~3.5 - 4 Lakhs which is not a good rank to get into IIIT Delhi.

Other eligibility criteria for IIITD is that you must have secured 70% or above score in your 12th boards.  In fact your rank count is already in lakhs and at this rank it is very difficult to get into any government college in India as well as any good private college too.

Only thing I can say is that you should prepare better for your next session and secure a good percentile so that you can only get a good government college. Set your target for a good score and prepare accordingly.

You can also use our college predictor link to know better about which college you can get at what percentile.
