M.Sc. Curriculum

Entire two year M.Sc. Programme in Mathematics has been divided into four semesters.

Stages of Progression:

First Year: In the 1st year (Two semesters), basic core courses are the main contents.

Second Year: 2nd year courses have been designed to accommodate more applicable elective courses and a project. Over all 5 elective courses is an attraction since this choice accommodates a series of 4 structured courses (if offered).
