The IAT examines your core knowledge in all four topics, unlike the majority of engineering and medical entrance exams. The questions rarely require complex calculations, and when they do, you can use a calculator to speed up the process.


I cannot emphasize enough how vital it is to understand the theory and practice questions for any particular chapter.


With as many chapters of the syllabus as you can, try to be as thorough as you can.


Another thing to note is that the IAT gives the same weight to the PCMB as the other four parts. There are three potential out


You have PCB; try learning the fundamentals of maths. For instance, matrices and determinants, fundamental series and sequences, statistics, 3D geometry (this year, there was an incredibly simple 3D geometry question), etc. You can also try learning the fundamentals of calculus and functions if you can (or wish). But don’t put too much emphasis on math. Just ignore arithmetic if you don’t feel very comfortable with it. You can move forward if the rest of your subjects (PCB) are strong. The biological analytical units (cell division, genetics, molecular basis of inheritance, biotechnology, evolution, ecology, and biodiversity) are popular on the IAT, so be sure to thoroughly cover them. Simply read the full NCERT Biology text line by line to retain the knowledge.

You take PCM: Every year, the math questions get progressively more challenging. Calculus should be thoroughly studied because it is the subject that is tested the most. Cover all the simple chapters, especially statistics and 3D geometry (the ones I specified in the PCB section). I must emphasize this again: Studying the analytical biology units (listed in the PCB part) will be very beneficial to you. Try practicing a few adv questions.

You are among the fortunate few if you have PCMB. Clear up your foundations in each subject and practice solving issues. To ensure that you are able to answer any straightforward questions from each chapter, try to have a fundamental understanding of every chapter.

You should watch PhysicsWallah’s (Alakh Pandey) lectures in physics and chemistry because he does a fantastic job at explaining the concepts. He is to thank for my passion of physics.


Make an effort to comprehend the origins and significance of all the critical formulas on the syllabus. You won’t need to memorize them this way.


Everyone should avoid going into hyper mode and memorizing everything they can. This will have a negative net effect. Practice NEST papers because they are more challenging than IAT questions and will give you a better idea of your level of competence. Give the NEST if you can to familiarize yourself with the exam environment and to evaluate your performance.


Since you have three minutes to answer each question in the IAT, time isn’t a big deal.

On exam day, be composed and approach the questions with clarity. On the day of the exam, I tried to picture myself relaxing at home, answering the questions as I went along.


Don’t panic and concentrate on your second attempt if you are determined to pursue a career in pure sciences research but fail at your first effort.

Hope this was useful.
