Hello Madan
As far as i know, the eligibility criteria for DRDO and ISRO is 65% in btech and it is not considered as a second division. I have seen many people with 66% in Btech and doing job in ISRO. Many colleges provide marks on the CGPA basis which is bit different than percentage.
Candidates can check B.Tech Cut off for Top IITs & NITs here.
