JEE Advanced 2017

JEE Advanced 2017 was conducted on 21^st May 2017. Slightly over 220000 students were qualified to appear for the exam. Paper 1 was conducted in the morning 9.00 to 12.00 hours and Paper 2 was conducted in the afternoon 14.00 to 17.00 hours. There were 10 versions of the exam paper.

The order of topics has remained to be the same over the past four years – Physics, Chemistry and Mathematics. In difference to previous years, the options were jumbled across versions for ALL questions in this paper. The paper as a whole was moderately difficult as per students.

The question pattern was, of course, different from any of the previous years. A new type of question comparable to Matching list but with three columns and four rows in each has appeared in JEE Advanced 2017 paper. There were 18 x 3 = 54 questions altogether and the total marks were 61 x 3 = 183. The question pattern is as shown below:

* One or more correct option(s) type questions awarded partial marks, i.e. for darkening a bubble corresponding to each correct option, provided NO incorrect option is darkened, 1 mark will be awarded.

Physics

In the Physics part, questions were of moderate difficulty level. Distribution of questions among various topics was almost uniform. The nature and question positioning in most of the questions were different from regularly probed variants and required innovation to solve.

The difficulty level of the paper and the topic wise segregation are depicted below:





Chemistry

In general the questions in this section are aimed at checking in depth learning of concepts and also challenging the students to innovate on topics slightly out of boundary for the prescribed syllabus.

Yet, a general feeling regarding organic chemistry is that they are easier to solve compared with previous years’ and also with other sections of chemistry in this paper. But the brilliance of the students is really put to test in answering the Physical chemistry part. Students might have to spend more time per question to arrive at the correct answer(s) in ‘more than one correct option correct’ type.

In this year’s paper few questions from Inorganic Chemistry are difficult. These include data outside the normal range of syllabus for JEE Advanced examination and makes them tough.

Mathematics

The Mathematics part of the paper was of medium difficulty level. Few questions required lengthy solving. Some areas like Vector Algebra were totally left out in this paper. One can say that Algebra and Coordinate geometry once again ruled over the JEE Advanced paper.

Other than being thorough in the syllabus part, reasoning skills will be required to get to the answer in few questions.

Paper 2

The order of topics has remained as – Physics, Chemistry and Mathematics. Again, the options were jumbled across versions for ALL questions in this paper also. The paper as a whole was not very difficult as per students, probably because Mathematics posed lesser difficulty than all previous years; but Physics part was quite challenging and Chemistry also posed difficulties in huge contrast to previous years. The question pattern: there were 18 x 3 = 54 questions altogether and the total marks were 61 x 3 = 183. The question pattern was different from Paper 1 and is as shown below:

* One or more correct option(s) type questions awarded partial marks, i.e. for darkening a bubble corresponding to each correct option, provided NO incorrect option is darkened, 1 mark will be awarded.

Physics

Difficulty level of majority of the questions are high compared to the first paper. Again the distribution of questions from different subject areas was uniform. Most of the problems require a creative thought process to solve it in a fixed time frame.

Chemistry

Compared to paper 1, paper 2 was not too different both in difficulty level of questions and in extensions of concept areas beyond syllabus. Only in this paper the off-syllabus questions were mostly from the Physical chemistry area. Questions involved more advanced topic references and were difficult from the regular student point of view.

The organic chemistry part was little soothing to the students as it was moderately difficult but involved applying logic to reach the correct answers.

Inorganic part of the paper was considered easy to answer. As time saved on this may be spent to approach more difficult questions, one can say that paper 2 was much more balanced.

The difficulty level of the paper and the topic wise segregation are depicted below:





Mathematics

As expected the Mathematics portion in paper 2 was at the level of paper 1. Questions from calculus were tough, lengthy and demanding more time. Both sets of paragraph based questions (one from theory of equations and the other from vector algebra) required some innovation to get to the solution.

Calculus ruled the paper (over 50%) with no representation from Coordinate geometry, even Algebra was scarce in comparison to Calculus part.

Overall, students would have felt slightly elated after paper 2 Mathematics.
