I would not recommend any of these. You should opt for some other better college for civil engineering.

What info are your seeking? Please reframe your question.

What is your interest field? If your interest lies in civil then you should choose civil branch.

In India percentage is important but don't panic practicing previous question papers will gain you percentage. You must gain knowledge and concepts that is very important.

You can go for agricultural engineering if you are interested.
