After 10 th class
You have to score as much as you can in 12 th class.
And most of the engineering colleges give admission on basis of JEE mains marks for which the eligibility criteria is minimum 75 % marks in 12 th boards ( for general)
minimum 65%marks ( for ST/SC)
and some other criteria.
So good luck.

Hello Dear

Unfortunately you can't be able to take the admission in the CSE Engineering in any of the college / University after the completion of your class 10th after 12th only you can be able to take the admission in the respective college based upon your percentage of class 12th. Overall it's better to have the CGPA of 8.0 in your Class 10th.

All the best
