IAT for IISERs

From 2024 onwards, admissions to IISERs are exclusively through the IISER Aptitude Test and JEE Advanced (IAT). There is no JEE Mains channel or KVPY channel for admission in IISER anymore.

Test Pattern

IAT is conducted as a computer based test in the centers across India.

IAT consists of 60 questions: 15 questions each from Biology, Chemistry, Mathematics, and Physics.

Total time for answering the test is 3 hours. Questions are of multiple choice type with only one correct answer.

• Each correct answer is awarded 4 marks.
• Each incorrect answer leads to the deduction of 1 mark.
• Unanswered questions are awarded 0 mark.
• Therefore, maximum marks awarded in IAT are 240.

The total marks obtained by a candidate out of 240 is considered for preparing the Rank List.

Not every candidate appearing in IAT is awarded a rank. Rank cut-off is announced at an appropriate time. Further, getting a rank does not guarantee offer/admission to an IISER.

Syllabus

The syllabus broadly follows the NCERT syllabus for classes 11 and 12. For 2025 exam, it will follow the rationalized syllabus of 2024-25.
