Hi Anurag,
Hope you are doing well. It is not necessary to have some deep knowledge about programming before going to college. Even if you know some basics of programming languages like C Programming, it's fine. Even it is not necessary as most of the students entering CSE will be from biology stream. The first year of CSE only deals with the basic subjects like Physics, Chemistry and so on and also a special subject like C Programming where they will teach about the programming language from scratch. So there is no need to panic. I hope you got the point after reading this answer.

Best of luck.

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.
