IISER Cutoff – Board-wise and Category-wise Cutoffs (Released) 

Indian Institute of Science, Education & Research has released the IISER cutoff 2021. Candidates can visit the official admission portal i.e., iiseradmission.in to check the cutoff. The conducting body determines the board-wise cutoff marks (out of 500) that the applicants have to score (in class 12th from their respective boards) to be eligible for the IISER admission process. 

It is mandatory to meet the cutoff score to be eligible to apply for the IISER (irrespective of the channel of admission). Usually, the IISER cutoff is set on the basis of the top 20 percentile scores in various state & central boards of education. The IISER cutoff includes the names of almost all the major boards operating in India. However, the CBSE cutoff marks are considered for those candidates whose boards are not listed in IISER cutoff.   

The institute considers numerous factors to determine the IISER cutoff such as seat intake capacity at different campuses of IISER, previous year’s cutoff trends, etc. Since candidates have the choice to apply for IISER through 3 different channels, this group of institutions follow a slightly different way of admission. Unlike other institutions, IISER releases the board-wise cutoff marks before the admission process instead of releasing cut offs later. This is because IISER does not disclose the marks or ranks of the candidates while allocating them the seats. Instead, it just releases the list of admit card numbers/application sequence numbers of the candidates who are allotted a seat provisionally.

IISER Cutoff – Factors Determining the IISER Cutoff Score

The Indian Institute of Science, Education & Research will determine the IISER cutoff after considering the following parameters:

  1. Previous year’s cutoff trends
  2. Top scores in class 12th of different boards
  3. Seat intake capacity at IISER campuses 

Link between IISER Cutoff & Eligibility Criteria 

The IISER cutoff defines the eligibility criteria for admission. Candidates can check the points jotted down to know the relation between the cutoff score and the eligibility criteria for IISER.

  1. Applicants, irrespective of the channel of admission, satisfy the eligibility criteria only if they secure the marks in class 12th as per the IISER cutoff for their board
  2. Candidates can apply through SCB channel only if their respective boards (class 12th) are listed in the IISER cutoff list. Moreover, candidates can also apply via the KVPY or IIT-JEE channels.
  3. Is the name of your board is not listed in the IISER cutoff, either the IISER considers the CBSE cutoff score or you have to produce a certificate issued by your relevant board stating that you secured a position within the top 20 percentile holders in class 12th boards 
  4. If a board awards grades instead of marks in class 12th, candidates should produce a certificate issued by their respective board specifying the grades scaled into marks
  5. If a board provides only the aggregate score, IISER shall consider the aggregate score.

How to Calculate Marks out of 500 in Board Examination

Indian Institute of Science, Education & Research considers marks in five core subjects studied by candidates in class 12th namely,

  1. Physics
  2. Chemistry
  3. Biology/Mathematics
  4. One language subject
  5. Fifth core/main subject 

In case the marks scored in any of the five subjects are not evaluated out of 100, candidates must scale it accordingly.
