JEE Main 2017 Analysis Highlights

Lakhs of students prepare of JEE every year. A tremendous competition is witnessed every year when lakhs of students who prepare for JEE entire year, finally appear for the India’s most awaited exam- IIT JEE Main.

10.2 Lakh Plus aspirants….1781 Test Centres….23 IITs….2 Lakh seats!

No. of students appeared for JEE Main 2017

The Indian Institutes of Technology (IITs) successfully conducted their Joint Entrance Exam 2017 this Sunday, April 2 ’17, across the country. More than 10.2 Lakh students undertook this extremely strenuous exercise, and soon after it, Plancess presents you the shred of analysis of JEE Main 2017. If you have appeared this year, you can evaluate your performance & probability of selection. And if you are preparing for JEE Main 2018, you can have chance to understand insights of question paper.

Though the number has been steadily dropping over the years, this is still significant enough to make it the biggest exam on this planet. The falling number is a strong indication that students are paying more attention to state CET as compared to JEE Main.

 

The chances of getting selected might be one reasons for the same. Total number of seats available through JEE Main are not more than 50,000. The general perception about today's exam though was that it was not very difficult. In particular Maths was most simple; though lengthy.

Subject/Topic Wise Difficulty Level Analysis for JEE 2017

If we get into the details of difficulty of each subject. We can see that Physics had the maximum number of question which one would consider difficult. And Maths was easiest to attempt even though it was lengthy. Something which was common in all three subjects was the moderate difficult questions. “Although Physics has an impression of most difficult subject, it was quite straight forward. Overall the key to score well in the paper was proper practice and time management”, said Atharv, MEMS, IIT Mumbai.

 

Most of the questions in JEE Main 2017 were from class 12th Mathematics, Sahil, quoted “Theoretical aspects of Maths were quite simple but calculations consumed the time a way too much, which might affect the time management of students.” The ratio of questions in Physics from 11th & 12th, were almost equal. “Chemistry is more focused on NCERT. Only basic concepts along with theoretical knowledge were required to score well”, said Himank Jain, Chemical Engg, IIT Mumbai .

Similar to last couple of years, Maths was the simplest subject in JEE Main 2017, the winning point here was the time management. Since, the questions involved lot of calculations, the subject became lengthy and time consuming.

When talking about Physics, the ratio of questions from class 11th and 12th were almost equal. 16 questions were from 12th standard and 14 questions were covered from 11th standard. The difficulty level of which can be classified as – simple-11, moderate-10 and difficult-9. The questions asked very straight forward and did not include any complexity or different levels of calculations. The key to solve them were proper practice of basic concepts and tricky approach to solve numerical.

Lastly, about Chemistry, only 11 questions were covered from class 11th whereas 19 questions came from class 12th. Chemistry was the most difficult to attempt in JEE Main 2017 but the twist here was that most of the questions were focused from NCERT basic syllabus and only theoretical knowledge was re required to score well in this section. 12 questions in this section fall into the category of moderate difficulty level, 7 were difficult and 11 were relatively simple.

  No. of Questions-Easy No. of Questions-Medium No. of Questions-Hard Total Difficulty Level*
Physics 11 10 9 30 4.8
Chemistry 11 12 7 30 4.6
Mathematics 12 11 7 30 4.5

Topic wise marks distribution

If we get into the details of the subjects, starting with Physics. The most important deviation was that a significant amount of questions were asked from topics which usually don't carry as much weightage. For example, there were at least eight questions asked from Mechanics, which is slightly unusual. Also there were not as many questions from Electrostatics which is also a huge chapter and usually has significant weightage.

Most of the questions were from Methods of Differentiation and Applications of Derivatives from class 12th. 21 questions were from class 12th and 9 were from 11th. Overall, 12 questions were very simple, 11 moderate and 7 fall into the category of difficult.

Basic Principles of Organic Chemistry from class 11th and Biomolecules and Polymers from class 12th were most covered topics.

If we take a bird-eye view of JEE Main 2017, 68 various topics from Physics, Chemistry and Mathematics were covered. Paper was quite easy and if an aspirant has sound knowledge of basic and theoretical concepts and if he solves the paper calmly avoiding the silly mistakes he can do wonders. If we see the pattern of JEE Main in couple of years, tentatively it can be said that for JEE Main 2018 aspirants the difficulty level of Physics will be most and Maths shall be the simplest.

We wish everyone who appeared for this exam Good Luck for their results. The results will be out on April 27, 2017
