Factors Affecting IISER 2025 Rankings

There are several factors that can affect the relationship between marks and rank in IISER:

  • Individual Score: The score of IISER exam is decided by combining the score of A, B and C sections of the exam. This directly affects your rank.
  • Number of Applicants: As the number of applicants increases, the same score may not be enough and can affect your IISER 2025 ranking. With more applicants, the competition also increases and even a good score may not be enough.
  • Difficulty level: The overall difficulty level of the IISER exam also affects both marks and rank. As the exam becomes tougher, a lesser number of students can score well which means that your rank may go up even if your score is lower.
  • Availability of Seats: The number of seats for different programs in M.Sc. and Integrated M.Sc. programs are also different. If a program has a smaller number of seats, then the competition will be high. This will mean that your rank may go down for a similar score as compared to other programs where more seats are available.
  • Category Reservation: Like most exams in India, IISER also provides category reservation. In this case, separate cutoffs will be released, and accordingly, your rank will change.
