hi,

see the admission for integrated btech + m.tech course will depends on solely jee main score. however cutoff score changes every year and it depends on certain factors like number of participants, seat matrix etc. the last year closing rank was as follows,

NTA Ranking 8718 for CSE

10972 for ECE

HOWEVER AT THIS SCORE YOU HAVE LESS CHANCES.

if you are again preparing for jee main april session, you may use careers360 jee main knockout program to boost up your performance,
