Hello Aspirant,

It might be a bit difficult but you'll definitely be able to understand CSE if you have basic knowledge of Computer and any programming language. You must have studied Computers till 10th standard. And you'll must have studied HTML. So there won't be a big problem. In the first year of BTech the subjects for all branches are same, core subjects starts in second year. So don't worry you'll be able to do it.

All the best~
