To carry out this analysis, I have also talked to at least 60 students (intelligent, average, below average and poor) who took the examination this year to gauge the level of difficulty of questions and come up with the expected rankings vs score of students as well as the qualifying score for JEE Advanced. Not to forget that Class XII Board Examination marks have not been considered in this analysis. However, the inferences presented in this article should not be very different even after considering Class XII Board Examination marks.
JEE Mains this year had just one paper that had all three subjects – Mathematics, Physics and Chemistry with equal weightage. There were 90 questions in all, 30 of each subject and the total marks was 360 (120 marks for each subject). Overall, the paper was easy with the difficulty level of questions only slightly higher than Class XII Board Examinations. The type of questions asked were "Single Correct Answer Type" and "Assertion-Reason Type".
The real test here was of speed that I had been stressing on in my articles and during my interactions with students at Patna Book Fair and other seminars. So, students who had been following my series of preparatory articles on www.gyancentral.com, especially the last week preparation series should easily be able to qualify for this year's JEE Advanced. Especially in Mathematics, I had advised to go through Eduwiser's Mathematics Series by Prof. K. C. Sinha and you will notice that all the Mathematics questions asked in JEE Mains this year were directly from these books.
Fig. 1 : Level of Difficulty
Talking about the difficulty level, I personally found Mathematics easier than the other two. But based on the student and teacher feedback, the chart shows the level of difficulty of questions in each subject. So, among the individual subjects, Chemistry was supposedly easier whereas Physics was the most difficult (comparatively). The numbers also clearly indicate thatattempting the right questions in the examination can easily let any aspirant through, since there are sufficient number of easy questions asked; you just need to find them in the paper.
The above figures give you the topic-wise break-up of each subject. In each subject, if you had concentrated on preparing the chapters I had asked you to, you must have scored well. As expected, Coordinate and Vectors/3-D formed 27% of the Mathematics portion and all these questions were pretty straight forward and hence less time-consuming. Algebra formed the major portion of Mathematics as is always the case.
In Physics, Heat, Electrostat, Current& Magnetism, Modernand Sound formed more than 50% of the Physics paper. In Physics, a couple of questions were tricky and one question from Modern Physics (the one on modulated frequency) was out of syllabus, which made the paper a little difficult.
In Chemistry, if you had control over Physical and Organic Chemistry, the paper must have been a cakewalk for you.
Coming to the most important part of this article – expected ranking of students who know their approximate scores and the expected cut-off for JEE Advanced 2013.
Since I believe in equal opportunity for all, I am only going to discuss the cut-offs for the General Category. According to my analysis, the topper is expected to get about 342 marks. I talked to the FIITJEE topper and he has scored 330. So, the topper is expected to be from some other Coaching Institute. The competition will become very tough in terms of marks as we go lower down the rankings. The cut-off for JEE Advanced for General Category according to me, should be around 129 marks (refer the given table; considering only 51% of 150,000 = 75000 approx. will qualify for JEE Advanced.
Tabulated above is the aggregate score against one's expected ranking according to my analysis.
The actual data will however be known only when the results are out on May 7, 2013 (on this date, only the scores will be released). Until then, we can only publish the 'expected' rankings and 'expected' cut-offs. The Class XII marks also need to be considered for the actual rankings. The way forward for students now is to focus on other major examination(s) – be it JEE Advanced and/or some regional engineering entrance examinations.
Wishing all the students All the Best for their results and their upcoming examinations. Hope the article helps!
