FAQs

Q1. Which syllabus is to be followed for IAT 2026 preparation?

Ans. The IAT syllabus follows the rationalized NCERT Class 11 and 12 curriculum for Physics, Chemistry, Mathematics, and Biology. Aspirants are advised to refer to latest NCERT books for all four subjects.

Q2. Are all four subjects compulsory for the IAT 2026 exam?

Ans. All four subjects—Physics, Chemistry, Mathematics, and Biology—are included in the exam, with 15 questions each. However, eligibility requires qualifying in at least three subjects; preparing for all sections increases the chances of achieving a high score.

Q3. Are there any specific chapters to focus on for each subject?

Ans. While all chapters from Class 11 and 12 are important, commonly emphasized topics include Modern Physics and Electromagnetism for Physics, Organic Chemistry for Chemistry, Calculus and Probability for Mathematics, and Genetics and Physiology for Biology. Nevertheless, selective study is not advisable; the test can draw questions from any part of the syllabus.

Q4. Is the difficulty level of IAT 2026 higher than the board exams?

Ans. The IAT exam is generally conceptual, with difficulty at or slightly above the higher secondary level. It assesses application skills more rigorously than most board exams.
