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.
