Analysis of JEE Main Important Chapters and Chapter wise weightage for JEE Main 2026
Our experts have analysed the previous years’ papers. This analysis predicts the average number of questions based on the difficulty level of JEE Main. The questions are divided into easy, medium and hard level questions and questions from these topics have a very high chance of being asked in JEE Main 2026.
The difficulty level distribution of the previous years’ papers suggests that about 83 percent of the JEE Main paper consists of easy and medium level questions. Further analysis of the medium level difficulty questions indicates that the questions are a bit trickier and takes the students a good amount of time to answer.
A majority of the questions in the medium difficulty level are from Physics. Answering these questions could be time-consuming for most of the JEE Main aspirants.
JEE Main Chemistry portion is one of the easiest for most students, and many of the students score pretty well in this section. In Chemistry, there are more theory-based questions that takes less time to answer, compared to Physics and Mathematics questions. The concepts in the Chemistry section could be a bit more complex. So, an aspirant who has practiced these questions would be able to answer these quickly. This section can give extra boost to your marks in JEE Main.
JEE Main Mathematics section is completely numerical based and requires a lot of practice. Even if your fundamentals are clear and you know the formulae, you would still need to practice the questions based on the JEE Main mathematics concepts. A good understanding of the concepts will help you sail through the Mathematics section of JEE Main easily.
