For JU CSE, you require a rank of under 150 (to be safe). So 130+/200 must be sufficient for that purpose. Keep your target high. 

Board eligibility criteria:-

Minimum Marks: Candidates have to secure minimum 45% marks (40% for SC/ST/OBC, PWD category) in the above three subjects taken together.

Qualifying Exam: Candidates have to pass 10+2 examination from a recognized board.

All the very best and good luck.

Which branch you are talking about as I can help you with the rank range like in pevious year, the closing rank for round 1 for General category was 2699. 

Good Luck!!!
