Both JEE and KVPY Channel Have Been Abolished:

In the past, the Indian government has abolished the Kishore Vaigyanik Protsahan Yojana (KVPY), which has had an impact on admission processes for IISERs. As a result, IISERs have stopped granting admission based on KVPY scores. However, this year IISERs have announced that admission will be granted through the IISER Aptitude Test (IAT) exclusively. This means that admission will not be based on Joint Entrance Examination (JEE) scores.

How will this Impact the Candidates?

This change is expected to increase the level of competition for admission through the IAT since students who previously sought admission through the JEE channel may also appear for the IAT, leading to an increase in the number of candidates. As a result, the cutoff for admissions may be slightly higher this year.

Is there Any Change in Eligibility Criteria?

Earlier, only first droppers were allowed to register for IISER or IAT. But this year, anyone who has qualified XII or equivalent from any recognized board in 2022, 2023 or 2024 will be eligible for IAT. This means that second droppers are also allowed this time. So, if you are a second dropper, this is the best opportunity for you.

Following are all the eligibility criteria:

  1. You must be an Indian Citizen
  2. You must have passed Class XII or equivalent exam with science stream in 2022, 2023, or 2024
  3. You must have taken at least three subjects among Biology, Physics, Chemistry and Mathematics in your +2
  4. If you belong to the SC/ST category, you must have secured 55% aggregate or equivalent grade in XII. If you belong to any other category, you must have secured 60% aggregate or equivalent grade in XII

Is there Any Change in the Syllabus?

IAT is based on the NCERT for Class XI and XII. But more than NCERT is required. Hence, check the SciAstra app and website for IAT resources. Also, check the SciAstra app for PYQs of IAT. Also, download and check the SciAstra app. A PDF of the syllabus is present in the ‘free materials section’ in the app. There might be changes in the syllabus this year. Please follow our YouTube channel ‘Vivek NISER | SciAstra’ for the latest updates.

Is there any change in Syllabus?

Till now, IISER has not announced its exam pattern for this year. Hence, the exam pattern is expected to be the same. The exam pattern that IAT generally follows is given below:

IAT is a computer-based offline test. It consists of 60 questions, 15 each from four sections: Mathematics, Chemistry, Physics and Biology.

The marking scheme is given below:

  • For each correct answer, you will be awarded +4 marks
  • For each incorrect answer, one mark will be deducted
  • No marks for unanswered questions

All the questions are Multiple Choice Questions with only single correct answers. Total time for answering the test is 3 hours or 180 minutes.

Are both Math And Biology sections compulsory?

The common problem of both PCB and PCM students is that both the Maths and Biology sections are present in the IAT question paper. These sections are not optional. Although, since both PCB and PCM students appear for the exam, if you skip one of these sections, it should not hamper your result much.

But note that if you attempt both sections, it greatly enhances your chances of getting selected. But how can a PCB student solve the maths section and vice-versa? SciAstra comes to your rescue. We have several courses for IAT preparation, and we specifically focus on PCB and PCM students to help them solve the sections that they have not studied in their +2.  Click here to learn more about our course.


Students admitted to IISER might be eligible for a limited number of INSPIRE scholarships. The scholarship will be granted based on norms set by the Department of Science and Technology, India.

How Much is the Application Fee?

  • INR 2000 for candidates applying under GEN, EWS and OBC-NCL categories
  • INR 1000 for candidates applying under PWD, SC/ST categories and for Kashmiri migrants
