Hello,

No it is not possible to go for you to go for medical science after pursuing engineering stream. You can study them but you can't put them in practice. In short you can learn them only.

In the field of CSE there are many thing to do. You have just started studying it but there are many thing and by the end of 4rth year you will think that why i haven't studied all these before. so to make your career smooth focus on the the stream you have choosen. You can't go both the side at the same time.

Study and excel!

Hope it helps!
