I believe, you should never consider a Branch lower than CSE, IT or least ECE, when your dicuss admission in Private Universities like VIT, KIIT, SRM or Manipal. I would suggest you to consider CSE at MU Jaipur, over Mechanical at VIT Vellore. Manipal University Jaipur has excellent infrastructure and facilities besides having strong placements for CSE with more than 90% getting placed last season, with an average package of 6 LPA.  MUJ even has a very strong ROI Factor over VIT Vellore, where Total Education Costs are less than 12 Lakhs for 4 Years.
