Hello utkarsh somvanshi 

With 77K rank chances of CSE are quite slim but you can get mechanical engineering, or you can also try for elcetrical and electronics engineering , if you are lucky nough you can get ECE also but it depends on the situation though getting CSE is bit tough or almost not possible.

rest you can get the core branches like: Mechanical, Civil, etc

and in other branches you can also get ECE or EEE.

Hope that helps!
