Hi,

Yes, you can apply for MSW in 2019 but you need to justify the gap at the time of admission.

There is no entrance that is been conducted for admission in BSW. Please visit the link to understand the criteria for admission: https://www.shiksha.com/humanities-social-sciences/social-work/course/bachelor-of-social-work-hons-visva-bharati-university-west-bengal-other-240023

Dear,
The eligibility criteria for admission in M.Sc in chemistry is 45% marks in B.Sc.chemistry Honours and pass marks in Mathematics as a subsidiary subject. Other formalities as decided by the University for admission required to be observed. So it is clear from Eligibility criteria of admission in M.Sc. in Chemistry that after B.Tech in CS you can't do directly M.Sc. in Chemistry.
