i m not good in programming.So will i take cse in B.Tech?

As part of curriculum, you have to study programming subjects like C, C++ and JAVA. If you dont like programming, I would suggest you to go for BCA and MCA afterwards. From job perspectives, there are other roles like Quality assurance, network or desktop administrator also which are offered to CSE

if u don't know basic programmings then i will not suggest u to take CSE.....rest is on u....if u can cope up there then u can take it also.....it depends on your capability
