I wouldn't suggest you to go for it. My friend got admitted in 2015 batch of MSW, but later he dropped out.
Manipal is known for B.tech and MBBS. MSW faculty is okay. They don't have placements and also you will not get the exposure which you can get in other specialised colleges of MSW.
If you're really interested in development sector then I would suggest you to take a year gap prepare for TISS, DU, JAMIA, Nirmala niketan etc. These are the top colleges for MSW.
Meanwhile you can do internship, volunteering work. This will help you with your interview as well as SOP.
Hope this was helpful.
All the best.
