Common questions about preparing for this exam
IISERs admit through three channels: (1) IISER Aptitude Test (IAT), (2) KVPY/SCB fellowship holders, and (3) JEE Advanced top percentile. The IAT is the most common route and the one most students prepare for.
Yes. Unlike NEST where you choose subjects, IISER IAT tests all four — Physics, Chemistry, Maths, and Biology — in one paper. You cannot skip any subject, so balanced preparation is essential.
IISER IAT focuses on scientific aptitude and reasoning rather than formula-heavy problem solving. Questions test whether you can think like a scientist — applying concepts to new situations, interpreting data, and connecting ideas across subjects.
IISER cutoffs vary by institute (Pune, Kolkata, Mohali, Bhopal, Berhampur, Thiruvananthapuram, Tirupati). Generally, a score in the top 5-10% of IAT test-takers gives a good chance. Pune and Kolkata tend to have the highest cutoffs.
There's significant overlap since both test scientific aptitude. However, IISER IAT covers all four subjects equally, while KVPY/SCB streams focused on specific areas. Use KVPY past papers for practice, but prepare all four subjects for IAT.
