With an OBC-NCL category rank of 39,990 in JEE Mains 2025 and a CRL of 1,22,358, and since you’re from Madhya Pradesh, your chances of getting CSE at SGSITS Indore through JoSAA are a bit tight but still within reach. Last year, the closing rank for CSE at SGSITS for the OBC-NCL category in the home state quota was somewhere around 35,000. You're slightly above that range, so you might miss out in the first round, but you still have a realistic chance in the later rounds, especially if there's any drop in cutoffs this year or if seats remain unfilled.

Even if CSE becomes too competitive, you’ll have a strong chance at getting IT or other related branches at SGSITS, which are also solid options and have good placement records. Also, don't forget that MP DTE state counselling could open more possibilities since it gives preference to state board students and uses JEE ranks too.

So yes, while CSE at SGSITS isn't a guaranteed lock at your current rank, it's still very much possible with a little patience through multiple counselling rounds. And if not, IT is definitely a strong backup you’re likely to get.
