JEE Advanced Analysis 2018: IIT Kanpur conducted the JEE Advanced 2018 exam on 20th May 2018. The JEE Advanced official answer key was released on 29th May 2018 and the JEE Advanced result will be declared on 10th June 2018. Experts at Embibe have analyzed the JEE Advanced online question paper. The JEE Advanced Analysis 2018 will give detailed information about the difficulty level of each section as well as the overall difficulty level of the exam. Information regarding the ideal time, distribution of questions, type of questions asked in the paper, etc. will also be provided.
The JEE Advanced Analysis will give students an idea about how they have performed in the exam. They will also get an idea about the likelihood of them cracking the exam. It will be helpful even for students appearing for JEE Advanced 2019. Read on to find out the detailed JEE Advanced Analysis 2018.
Detailed JEE Advanced Analysis 2018
Embibe has large amounts of student attempt data collected on our platform over many years. This along with Embibe’s Knowledge Graph gives us insights into the paper on various dimensions – difficulty, time to solve, important concepts and chapters, and chapters and concepts where students are likely to make mistakes, etc. As you can see, Embibe has the ability to perform a unique analysis of the JEE Advanced 2018 Paper.
JEE Advanced Analysis: How Difficult Was The Paper
Questions are rated on a difficulty scale of 110 (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:

JEE Advanced Analysis: What Skill Types Did The Questions Test For
Any particular question on an exam paper will require the application of different skills to be able to correctly solve it within an acceptable amount of time. We tag every question with the specific skill type that it tests for. The figure below shows the distribution of skills that were covered by the questions in this year’s paper. We can see that Analytical and Applicationbased questions accounted for over 85% of the questions asked. Synthesis skill is also tested in 10% of the questions.
JEE Advanced Analysis: What concepts will students not do well in this year
At Embibe, we have powerful data that captures how students perform on various concepts. This data is based on millions of student attempts collected over the years on our platform. Using this data, we have the following concepts where students will most likely go wrong, most likely go overtime, and most likely make careless mistakes this year.
