hi anshul,

thankyou for approaching us. it will surely be a little tough task to get on with the flow if you join a english medium college and in CSE . but trust me it is just a piece of cake. they will have basic computer based workshops in which every one who donot know anything about computer are tought the basics about it. so, just because you donot know how to operate a computer so far you dont have to step back from CSE branch. if you really wanna take up CSE , just go for it. you can suceed .

keep up hope 

all the best:)

no problem, if you don't studied computer till 12th but still you can do b.tech in CS branch as they start with the basics and computer science is one of the hottest branch now a days.
