The IISER Aptitude Test (IAT) is the primary gateway for admission into the 7 IISERs (Pune, Kolkata, Mohali, Bhopal, Thiruvananthapuram, Tirupati, Berhampur) across India. The 3-hour computer-based test covers Physics, Chemistry, Mathematics, and Biology. To secure a seat, general category students typically need a score of 130+ out of 240.

Exam Pattern and Marking Scheme

The IAT is designed to test conceptual clarity rather than speed. The paper consists of 60 questions—15 from each of the four core subjects. Each correct answer awards 4 marks, while an incorrect answer carries a negative penalty of 1 mark. Unanswered questions receive zero marks. Unlike JEE Main, which heavily emphasizes mathematical speed, IAT questions often blend multiple scientific concepts, requiring a deep understanding of core principles.

Subject-Wise Syllabus and Weightage The syllabus closely mirrors the NCERT curriculum for Classes 11 and 12.

• Physics: Mechanics, Electrodynamics, and Modern Physics form the core.

• Chemistry: Organic reaction mechanisms and Chemical Thermodynamics are heavily tested.

• Mathematics: Calculus, Vector Algebra, and Probability are high-weightage topics.

• Biology: Genetics, Molecular Basis of Inheritance, and Ecology require thorough revision.

IAT vs. JEE and NEET

While JEE candidates often skip Biology and NEET candidates struggle with high-level Mathematics, the IAT levels the playing field. Since all four subjects carry equal weight (60 marks each), students who can score above average in their "weak" subject gain a massive percentile advantage. The difficulty level of Physics and Chemistry sits exactly between JEE Main and JEE Advanced, while Biology aligns closely with NEET standards.
