Hello Nancy,
MS University in Vadodara is quite famous for its excellence in academics. Students who have passed out of this university are considered as the cream in the whole of Gujarat. In view of this, lots of companies make a beeline for recruiting students from MS University. As a result, I would like to advise you not to worry as far as placements are concerned if you are studying in this university.

Dear, first of all try hard to score more in MSU, Vadodara. For computer science engineering you have to score minimum 45% in HSC if you belong to General or OBC category and minimum 40% if you belong to SC/ST category.

All of the 3 colleges which you mentioned are the technical institutes providing best of the technical exposure to there students and know-how. These institutes does have management programs but are average in providing you with any good management skills and exposure. They will give you placement but the company might not be of your core MBA specialisation (Marketing, HR, Finance etc. ). So in my opinion opt for a good Business School for the MBA course.

There are many courses available in the MS University for class 12th student. There many Bachelor's degree courses available like B.Sc, B.Com, B.Tech, etc. For more courses refer the attachment given.
