The Curious Debate of JEEMain 2014 Cutoffsâ€”Where Do You Stand?
All right! Just because the curious case of JEEMain 2014 is finally over doesnâ€™t mean that students are finally out of stresszone. Obviously,postexam stress is harrowing experience for any student, which grows bigger with outofthebox result predictions following any exam by critics.
In case of JEEMain 2014 (that was held on April 6^{th}, 2014, yesterday), queer result predictions for students were out in a few hours after the exam. And there were over hundreds of websites each with their different cutoff predictions. Some predictions help JEEcandidates determine their rankings or their performance in the examination while some just add to their confusions.
Cutoff predictions in JEEMain like other exams are mainly based on detailed paper analysis. So letâ€™s analyze JEEMain paper and try to fathom the mystery over result predictions.
The JEEMain examination was based on physics, chemistry, and mathematics subjects from class 11^{th} and 12^{th}. Letâ€™s take a look at the examâ€™s question distribution by the help of the table given below:
Question Distribution:
Physics  Chemistry  Mathematics  Total  
Class 12  17  19  12  48 
Class 11  13  11  18  42 
There were total 48 questions from class 12â€”17 questions from physics, 19 from chemistry, and 12 from mathematics. On the other hand, there were total 42 question from class 11â€”13 from physics, 11 from chemistry, and 18 from mathematics.
Marks distribution in the exam was comparatively higher in class 12th category than class 11the category. Letâ€™s go through the table given below for a clear understanding:
Marks Distribution:
Physics  Chemistry  Maths  total  
Class 12  68  76  48  192 
Class 11  52  44  72  168 
Questions from class 12^{th} had more marks than questions from class 11^{th}. There were 192 marks from class 12^{th} and 168 from class 11^{th}.Paper analysis can also prove useful for the determination of expected cutoff the colleges. However, a lot of other aspects are taken into consideration while analyzing a paper to determine expected cutoffs. We must analyze JEEMain paper on its difficulty levels of questions and marks distribution.
We can distribute these two levels in two different tables:
Difficulty level of questions:
Physic  Chemistry  Maths  total  
Difficult  7  6  4  17 
Moderate  10  9  14  33 
Easy  13  15  12  30 
Difficulty Level in Marks distribution:
Â  physics  chemistry  Maths  total 
Difficulty  28  24  13  65 
Moderate  40  36  47  123 
Easy  52  60  40  152 
Comparing these two tables, we get more number of easy questions and marks.Letâ€™s take a look at the expected cutoff released by Resonance (a leading coaching institute) based on its analysis of the exam. These are minimum scores predicted by the institute for admissions to the various engineering degree courses in the IITs, NITs, Central Institutes and other engineering colleges across the country.

Expected cutoff depends a lot on various factors such as number of JEEMain candidates, number of seats, and the level of examination (that we have already analyzed above).TheÂ cut offÂ also varies for different category students such as General, OBC, SC/ST, etc.
We have brought you both subject and topic wise paper analysis of the exam to help you come up with your own expected cutoff:

Based on this paperanalysis, many coaching institutes like those mentioned above in the article have come up with their own cutoff predictions. But how accurate are these cutoff predictions anyway?
Following these predictions blindly will not serve any purpose; we must look beyond what we cannot see. If you too analyze the paper carefully, then you can also come up with an accurate cutoff prediction. And who could be the best person than you to check your own performance in such an important exam.
