JEE Main Analysis: India is home to some of the best engineering colleges in the world. Students from across the world come here to pursue engineering. In view of the stiff competition and scarcity of seats, every JEE aspirant’s dream is to crack JEE Main. To do that, they need the JEE Main Analysis. That is what this post is all about – to provide you with the JEE Main Analysis 2018.
While JEE Main 2018 is yet to be conducted, we can only refer to the JEE Main Analysis 2017 in order to get an idea of how the 201 paper is going to be like. Read on for the detailed JEE Main Analysis 2017.
Note: At Embibe, we have ensured that JEE aspirants avail mock tests free of cost. We suggest you attempt our mock tests and evaluate yourself before appearing for the examination.
JEE Main Analysis 2017
JEE Main Analysis – Concepts repeating every year
All the papers have come from a universe of 1750 concepts — This means that 30% of the concepts are in the definitive list of being important. Take a look at the table below to find the list of top occurring concepts according to our JEE Main Analysis. Also, this is an interesting table to see the concept build out every year:
There seems to be a diminishing addition every year to the number of concepts. Does this mean we are saturating the concepts in every test?
The next chart also shows you what is the repetition of concepts year on year. This is the commonality of concepts or repetition matching between tests across years.
Read the table below matching the column in red with the first row in red to see the overlap. For instance, the first row says the JEE Main 2013 7th April offline paper had 65 concepts in common with JEE Main 2014 11th April online paper and 76 common with JEE Main 2014 19th April online paper.
We couldn’t find any single concept that comes exactly the same way every year.
JEE Main Analysis – Chapters repeating every year
There are 18 chapters that have faithfully appeared every year in the paper. If you look at the CBSE syllabus, the ratio of distribution is almost 50:50 between 11th and 12th with the tilt slightly towards 11th at 56%. This is the definitive list of unmissable chapters for the JEE Main.
JEE Main Analysis – Maths chapters repeating every year
- Binomial Theorem
- Complex Numbers
- Indefinite Integration
- Matrices and Determinants
- Point and Straight Line
- Quadratic Equations
- Sequences and Series (Progressions)
JEE Main Analysis – Chemistry chapters repeating every year
JEE Main Analysis – Physics chapters repeating every year
- Electromagnetic Induction and Alternating Current
- Magnetic Effects of Current
- Ray Optics
- Semiconductors and Communication System
- Waves and Sound
Here is the commonality across chapters for all exams. Read the table below matching the column in the with the first row in red to see the overlap:
These chapters also appeared in the JEE 2017 offline paper.
JEE Main Analysis – Difficulty level
Is there a difficulty level variation across the years? We rate questions on a scale of 1–10. The difficulty level of the JEE paper ranges from 3.8 to 5.3 over the years with the average being 4.4.
JEE Main 2017 was on the easier side with an average difficulty level of 4.1.
JEE Main Analysis – Ideal time distribution section-wise?
It’s interesting to see that mostly the ideal time needed for the paper leaves about 10 minutes for revision if you really know everything. Overall, if we see the time actually needed for Physics, Chemistry and Maths section wise — this is how it looks across the years:
If you see carefully, Physics and Maths keep exchanging the ‘lengthy section’ title through the years.
JEE Main Analysis – Online paper vs. offline paper
Is the online paper actually tougher than the offline paper every year?
So, we were not prepared for this but it seems like:
1. The online and offline papers may have the same average difficulty levels overall but there has been a stark difference in difficulty levels in certain years. 2015 online students seem to have had a distinct advantage after which in 2016, this seems to have been corrected.
Let’s further see if the difficulty level difference was compensated by differential time spent:
Alas, no — not for the earlier years. Not only were the online papers easier, they were also less lengthy. This was corrected in 2016.
2. There is actually a pattern in the time for the lengthy section between online and offline papers.
Maths seems to be lengthier in online vs offline paper. Lets see what happens this year online. This year as well in JEE Main 2017 offline, Physics was lengthier than the Maths paper in the offline exam.
JEE Main Analysis – Skills required
Do specific skills matter more for the JEE Main?
Turns out obviously memory is important as a building block according to our JEE Main analysis. However, analytical ability, calculation and visualisation account for almost 56% of questions asked.
An example of a question on visualisation would be something like this question — cracking it is about being able to see it in your head. Abstract questions tend to be more on things that cannot be easily associated with concrete ideas like Moment of Inertia or Angular Velocity. See a sample question here.
We have seen, through our detailed JEE Main analysis, this pattern repeat through the years.
JEE Main Analysis – Embibe’s predicted paper vs. actual paper
How well did Embibe’s Predicted JEE Main Paper compare to the actual JEE Main 2017 Offline Paper?
So here is the litmus test. It was very brave of us to actually use a combination of the above factors and a lot more data to attempt a prediction of the paper this year. 🙂 However, we really wanted to see if we could get close. Why don’t you look at the comparison below and decide for yourself?
In addition, 1 question came directly from the predicted paper in the actual exam and 1 other question from Embibe’s test series. All 18 common chapters were present and all concepts were part of the 1750 concept superset.
JEE Main Analysis – Concepts students will not do well in
We have this amazing data in our JEE Main analysis which can give you a very granular idea of the likely performance of students. This is based on millions of attempts collected over the years on these concepts. According to the data,
Top 5 concepts in which most students will make careless mistakes (or, as we call them, Wasted Attempts) in the JEE Main 2017 Offline paper:
Practice wasted attempts of most students in all chapters to avoid this issue.
Top 5 concepts in which most students will lose time in the JEE Main 2017 Offline Paper:
Practice overtime attempts of most students in all chapters to avoid this issue.
Top 5 concepts where students will lose the most marks in the JEE Main 2017 Offline Paper:
After preparing the JEE Main analysis, we come back to our original point: smart study is better than slogging. You will never love the entire syllabus. But you can make time to do more of what you love. All you need to do is plan your study around things that matter more and be smart about taking the test.
We hope our JEE Main Analysis has been of help to you. You may also be interested in our RANKUP product with predicted papers, personalised analysis and important questions tailored to your weaknesses.
