Hi

It is not necessary, the syallbus of JEE MAIN does not comprise of computer science subject. JEE test only your physics, chemistry and maths.

So if you are interested in making your career in computer engineering go ahead take computer science otherwise if you are not interested drop it.

hello dilpreet karu ,

It is not compulsory to take Computer science as your bi-focal subject if you want to take Computer sciemce engineering because all the basic will be taught in first year of Engineering .
