Hi

Thanks for your question,

B.Tech is a four year course and if you will take CSE branch then in the 1st year you will have almost same paper as other branches and they are mostly related to class 11th and 12th.In th next three years you will have to study mostly programming languages like C,C++,PYTHON,COA,JAVA,etc,etc,......and give their exams.

Hope this was helpful.

Good-Luck!!!!!
