Commonly asked questions
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.
