Introduction:
The IIT JAM (Joint Admission Test for Masters) is a national level entrance exam conducted by the Indian Institutes of Technology (IITs) for admission to various postgraduate courses. The IIT JAM Mathematics exam is one of the popular exams among aspiring mathematicians. The cutoff marks for different categories play a crucial role in determining the eligibility of candidates for admission. Let's explore the difference in cutoff marks for different categories in detail.

Difference in Cutoff Marks for Different Categories:

General Category:
- The cutoff marks for the General category in the IIT JAM Mathematics exam are usually the highest compared to other categories.
- The cutoff marks are determined based on factors such as the difficulty level of the exam, the number of candidates appearing for the exam, and the number of available seats.
- Candidates belonging to the General category need to score higher marks to secure admission to their desired course in prestigious IITs.

OBC-NCL Category:
- The cutoff marks for the OBC-NCL (Other Backward Classes - Non-Creamy Layer) category are relatively lower than the General category.
- The reservation policy allows some relaxation in the cutoff marks for OBC-NCL candidates, providing them with better opportunities for admission.
- However, the cutoff marks for OBC-NCL candidates are still higher compared to candidates from other reserved categories.

SC/ST Category:
- The cutoff marks for the SC (Scheduled Caste) and ST (Scheduled Tribe) categories are usually lower than the General and OBC-NCL categories.
- The reservation policy aims to provide equal opportunities to candidates from these categories, taking into account their socio-economic background and the need for representation in higher education institutions.
- The cutoff marks for SC/ST candidates are relatively lower, allowing them to secure admission to prestigious IITs with a comparatively lower score.

Conclusion:
The cutoff marks for different categories in the IIT JAM Mathematics exam vary based on the reservation policy and the number of available seats. Candidates from the General category need to score higher marks to secure admission, while OBC-NCL and SC/ST candidates have some relaxation in the cutoff marks. It is essential for candidates to be aware of the category-wise cutoff marks and prepare accordingly to increase their chances of admission to their desired course in IITs.
