Dear Shivam, almost everone is mad after getting mechanical branch but as you said that you are stuck in between CS and Mechanical, so, I’d suggest that CSE at IIT Mandi is pretty good. As far as academics are concerned, we have pretty good faculty with Director himself from CSE background.Our unique curriculum helps one to learn a lot of inter-disciplinary subjects( more than other IITs) apart from your core courses, which will help you gain inter-disciplinary knowledge.Placements for CSE are also good with almost everyone getting placed every year.For the past year, highest packages was around 27lpa, lowest-6lpa and average around 12–13lpa.Apart from all this IIT Mandi is situated at an awesome location.
Rest is up to you to make up your mind to choose a branch that interests you the most. Here I’d like to sugest the names of certain other reputed institutions as well which may be considered for comparison and contrast before actually getting admission somewhere – SRM University, Chennai,................DTU, Delhi and..................Lovely Professional University, Phagwara
