Introduction:
The IIT JAM (Joint Admission Test for M.Sc.) is conducted annually by the Indian Institutes of Technology (IITs) to provide admissions to postgraduate programs in various fields, including Mathematics. The cutoff marks in the IIT JAM Mathematics exam indicate the minimum score required to qualify for admission to the program. These cutoff marks can vary from year to year based on various factors.

Trend of Cutoff Marks:
The cutoff marks in the IIT JAM Mathematics exam have shown some fluctuations over the past few years. However, there are certain trends that can be observed:

1. Increasing Trend: In general, the cutoff marks for the IIT JAM Mathematics exam have been increasing over the years. This can be attributed to the increasing competition among candidates and the growing popularity of the IITs for higher education.

2. Year-wise Analysis: Let's take a look at the cutoff marks for the past three years to understand the trend more specifically:

- 2020: The cutoff marks for the General category in 2020 were around 32.5 out of 100. For OBC-NCL, the cutoff was around 29.3, for SC/ST, it was around 16.3, and for PwD, it was around 16.3.

- 2019: In 2019, the cutoff marks for the General category were around 32.5. For OBC-NCL, the cutoff was around 29.9, for SC/ST, it was around 16.2, and for PwD, it was around 16.2.

- 2018: The cutoff marks for the General category in 2018 were around 25. For OBC-NCL, the cutoff was around 22.5, for SC/ST, it was around 12.5, and for PwD, it was around 12.5.

3. Factors Affecting Cutoff Marks: The cutoff marks in the IIT JAM Mathematics exam can be influenced by various factors, such as the difficulty level of the exam, the number of candidates appearing for the exam, the number of available seats, and the overall performance of the candidates.

4. Preparation Strategy: Due to the increasing trend of cutoff marks, candidates should focus on thorough preparation and practice. They should cover the entire syllabus, solve previous year question papers, and take mock tests to assess their performance. Joining coaching classes or using online platforms like EduRev can also be beneficial.

5. Conclusion: The cutoff marks in the IIT JAM Mathematics exam have been on an upward trend in recent years. Candidates should aim for a score higher than the previous year's cutoff to increase their chances of admission. By following a systematic preparation strategy, candidates can improve their chances of qualifying the exam and securing admission to their desired postgraduate program in Mathematics.
