Hello Ishan,

To get a seat through CSAB counselling you have to first be eligible for the same. Since you are an EWS candidate, the cutoff for GEN-EWS is 78.21 percentile in JEE Main. CSAB Special Round (Spot Round) counselling takes candidates who have a valid JEE Main rank and are qualified and also who meet up the JoSAA eligibility criteria. Now as per your rank you can get a seat through CSAB for NITs,IIITs,GFTIs. Also you have an advantage of home state quota. So better apply for CSAB Special Round counselling and see which colleges are you getting and also which branches are being available to you.

Good Luck !!!!
