Hey aspirant,

I wouldn't be able to suggest you with which branch you should go for.As,this is a really important decision amongst the students.You should only go with that branch in which you feel you are more comfortable and interested.It's but obvious that you wouldn't want to waste your 4 years of life in studying something in which you are not at all interested.

Now, talking about all these 4 colleges on the basis of placement statistics then-
