CORE COURSE IXANIMAL

A CBCS offers the student a diversity of courses to choose from and the autonomy to decide on the place, pace and the time of learning. The Gauhati University has decided to introduce the CBCS system at the under graduate level from the session 2019-20. The CBCS syllabus for the B.Sc. (Honours) is prepared
