The cut-off for CSIR NET Mathematical Science is the minimum marks that one needs to obtain to qualify for the examination. It differs every year depending upon the number of applicants, the difficulty level of the paper, and the total number of vacancies. Generally, the cut-off is higher for Junior Research Fellowship (JRF) than for Lectureship (LS). The cut-off is released category-wise, that is, the cut-off for General candidates, OBC candidates, SC candidates, ST candidates, and PwD candidates are different. For Mathematical Sciences, the cut-off normally ranges between 25% and 50%, depending on the category and session. To achieve this, core topics such as Linear Algebra, Real Analysis, and Differential Equations should be focused upon. Mock test practice and analysis of previous trends of cut-offs can enable aspirants to set suitable preparation goals. Reliable sites like IFAS provide excellent guidance and resources to aid aspirants in meeting their required cut-off.
