First of all, I would congratulate you for getting a good rank in JEE Mains. Well, there seems to be a slight miss-match with the general trend of ratio between OBC Rank 1338 to General Rank 48k but According to your data if the OBC Rank 1338 You can get top branches like CSE, ECE, EEE in top 7 NITs like VNIT, NITC, NITW, NITRKL, NITK or MNIT which is a very good thing! Whereas it might be slightly difficult to get CSE branch in NIT-Trichy as CSE branch in NIT-Trichy has the highest cutoff amongst all NITs but you can still aim for CSE Branch in any of these 7 NITs (except for NIT-Trichy). Now talking about IITs, you need to provide your JEE Advanced Rank as JEE Mains Score cannot give you admission to IITs. So with this rank, You have very high chances of getting all top branches like CSE, ECE or EEE in top NITs. Good Luck for your Counselling!
