IISER 2026: Application Process, Admission, Closing Rank, Cut Off, Safe Score & Other Details

IISER Aptitude Test difficulty level is comparatively easier than JEE Main exam difficulty level. There are four sections in the exam, and all have equal weightage. Mentioned below are the details for the same:

• Biology: This section might sound a tough nut to crack for the PCM students, but a reasonable understanding of class 11 and 12 NCERT concepts can help you sail through this section. If you are not familiar with Biology try to ace the Maths section. As the number of test-takers has grown over the years, this section has also seen a surged difficulty level.
• Maths: For the Biology students, it might be hard to crack. You need to focus on 11th and 12th class concepts. You can search for the doable questions and solve them. The level is usually at par or even above JEE Mains. The Biology students can cover the scores in their specialised section.
• Physics and Chemistry: This section is usually easier than the above two sections. The scores obtained here can make-or-break your chances for counselling. The questions in these two sections cover the fundamental and essential concepts. It is better to score well in these two sections. The sections are not really tough. They are far away from the difficulty level of JEE Advance.

Overall, the exam is far from easier than JEE Advanced exam. The Biology students have the advantage to finish their section quicker. Make sure your fundamentals are clear and your reasoning ability is good. This should be enough to secure a good score.

IISER entrance examination is considered to be one of the finest and the toughest exams under Science stream undergraduate entrance examination as it provides the BSMS dual degree in the most reputed and research-oriented institutions across the country which is IISERs. On a comparison note, candidates will find the examination tougher than JEE Main exam, but below JEE Advanced. Unlike JEE or NEET the IISER aptitude test asks questions from both mathematics and Biology. Subjects which are found tougher in IISER entrance examination- Organic Chemistry can easily create hassle while giving the entrance examination as there are a lot of naming reactions, its electrophilic and nucleophilic attacks which are commonly asked in the examination. For the bio-background people, the Math section is not usually unscalable. With a decent understanding of regular 11th and 12th-grade concepts, you should be able to crack a few questions without much trouble. Of course, the caveat being that you rock it in the bio section and make up for it. So ensure that you don't falter at this juncture.
