With 83.64 percentile in JEE Mains, a CRL rank of 2,41,727, and category rank of 83,704, getting CSE in top NITs or IIITs may be difficult. But you can still try for lower-ranked NITs, GFTIs, or good private colleges, especially if you're applying through a category or female reservation.

Also check if your home state quota helps in state government colleges. Participate in JoSAA/CSAB counselling, and keep options open across different branches too .
