JEE Advanced Analysis: Important Insights
Some of the most important insights on JEE Advanced paper are as under:
- The total number of questions per exam has remained constant across the 3 years.
- Matrix Match Type Questions and Numerical Type Questions were introduced in 2018 while Integer Type and Single Option Questions were discontinued in 2018 across all subjects
- More than One Correct Type questions have been the most important with the maximum number of questions being asked from this type across all 3 years
- Students have given most of the Correct Responses in Matrix Match questions followed by Single Option Correct Questions.
- Students have given most of the Wrong Responses in Integer Type questions followed by Numerical Type questions.
- Students have not attempted questions with More than One Correct Answer the most.
JEE Advanced Analysis: How Difficult Was The Paper
Questions are rated on a difficulty scale of 1-10 (with 1 being least difficult and 10 being most difficult) specific to an exam. The box plot below shows the distribution of difficulty levels of questions in this year’s paper versus those from the previous two years. We can see that this year, the average difficulty level was very similar to that of the previous years.
The bar chart below shows the average difficulty level for each of the three subjects – Mathematics, Chemistry, and Physics. We can see that this year, Chemistry was the toughest section overall with an average difficulty level of 6.
JEE Advanced Analysis: How Long Was The Paper
Questions are also assigned an Ideal Time (the average time it would take top students to correctly answer the question).
For this year’s JEE Advanced Paper, the questions had an average ideal time of 151 seconds. The figure above shows the distribution of ideal times for questions in this year’s paper versus the previous years.
We immediately notice that this year’s paper is much lengthier than previous years, comparable to the 2013 papers.
The bar chart below shows the average ideal time for each of the three subjects – Mathematics, Chemistry, and Physics. We can see that this year, Chemistry questions were taking more time.
JEE Advanced Analysis: How Were The Questions Spread Across Chapters And Concepts
In total, the 108 questions in this year’s JEE Advanced Paper covered 57 chapters from Physics, Chemistry, and Mathematics. The figure below shows how many chapters were used in multiple questions this year. We can see that of the 57 chapters that were tested this year, 13 chapters had 3 or more questions asked.
And here is the list of chapters with 3 or more questions:

Each question also requires the knowledge of some set of concepts to solve them. There were 178 concepts covered in this year’s paper. This means that on an average, a student would have to draw from their knowledge of between 1 and 2 concepts in order to solve a single question. Looking at this data another way, the figure below shows how many concepts were used in multiple questions this year.
We can see that of the 178 concepts that were tested this year, only 25 concepts, less than 15%, appeared in multiple questions.
And here is the list of concepts appearing in 3 or more questions:

At Embibe, we have always believed that good data coupled with smart algorithms is the key to personalizing education at scale and enabling students to achieve their learning outcomes. The final section in our analysis drives from this point. It may not be possible for all students to love the entire syllabus as a whole and prepare with equal fervour across all content.
However, one must prepare for the exam in the smartest possible manner. Using Embibe’s data-driven insights and preparation strategies makes it possible for anyone to make the best use of the limited time available when preparing for some of the toughest exams in the world. You can also get free JEE Advanced study material, JEE Advanced practice questions, and JEE Advanced mock tests on Embibe.
