You should go for a B.Tech in CS, rather than a BSc degree. Most jobs usually ask for a 4-year long B.Tech degree or a B.Sc+M.Sc (5 years) in CS. So, you may face problems while applying for jobs. As for the colleges, DU will be a better option compared to CURAJ. In 2021, NIRF has ranked Delhi University 11th in India.
