Hello Anurag,
CSE branch is in highly demand these days. Being a 1st year student of CSE branch, it is not requred you to know anything extraordinary. You have to just learn very basics of coding programme like python and C. And even if you don't know anything about basic then don't panic as teachers are there to make you understand the topic. The thing you must have a laptop from the start of your 1st year.
I hope you will find my answer helpful.
All the best.
Hello Anurag, Well, You don't need to know anything before you chose CSE because the college will teach you everything from scratch. You just need to have a basic knowledge of C language which is the mother of all programming language. It depends on the teachers too. Some of the professors skip basic things assuming that the students will be knowing this. But most of them teach everything.
