which are all the basic things have to learn before joining btech or be computer science and engineering department in college
Hey!
The minimum eligibility is to qualify 10+2 with physics, chemistry and mathematics as core subjects. There is no such compulsion to learn any course or programming language. In general first year subjects include one of the programming language and during the other years of computer science engineering students are taught to get the required skills. However, it is good to have some knowledge any basic programming language or some basic software skills such as excel, PowerPoint, Word etc.
Thank you
