JEE Main is conducted by the Central Board of Secondary Education at Centers in 129 cities in India and abroad.This year, a total of 12 lakh engineering aspirants had registered for this national level entrance exam, which is also a screening test for JEE Advanced 2016. This number has slightly dropped from the previous years, where it stood at almost 14 lakhs. We bring you the detailed review of JEE Main, 2016 to help you understand the paper better.

Detailed Review of JEE Main:

There were 30 questions each from Mathematics, Physics and Chemistry.

Candidates, who appeared for the exam, said that the overall exam was tough. The questions were of moderate difficulty level with Physics section being the toughest. Questions from Chemistry section were the easiest. Solving the questions in mathematics was a lengthy process, and hence time consuming.

Physics section had majority questions from class 11 syllabus, Chemistry had about 70 per cent of questions from Class 12 syllabus, making the latter relatively easier for test takers to connect with. Mathematics was moderate with about equal share of questions from both class 11 and class 12. A detailed review of JEE Main from the experts suggested that the paper was overall difficult than the last year’s paper.

Students were given three hours to complete the paper. There is negative marking for wrong answers but no marks will be deducted for not attempting a question.

The detailed review of JEE Main is as follows:

Mathematics:

The difficulty level of Mathematics has been marked as moderate to tough. Compared to Physics, the Mathematics questions were easier. The questions were almost equally divided with all topics uniformly covered in Physics and Chemistry. However, Mathematics had fewer questions from Algebra and Calculus and more from Coordinate Geometry. As far as the distribution of questions from Class XI and Class XII syllabus is concerned, 57% of the questions were from the former and 43% were from the latter, reverse as that of the other 2 subjects. Majority of questions were from Sets, Statistics, Mathematical Reasoning, Vector/3-D Geometry, Co-ordinate Geometry, Differential Calculus and Algebra. The most surprising aspect of this paper was the 3 questions, which had been picked STRAIGHT from IIT-JEE papers of the previous years, with a single change in numerical values provided. Those who had prepared well for Advanced were at a benefit, as all three questions required a bit of thinking for those who hadn’t attempted them previously.
Overall score of 60-70 would be good.

Physics:

The overall difficulty level of Physics has been termed as tough. Some of the difficult topics included Simple Harmonic Motion, Modern Physics, Electrostatics, Heat and Thermodynamics, Work Power and Energy. Maximum questions were from Mechanics. The distribution of questions from Class XI and XII was 43% and 57% respectively. Good questions were asked from less popular chapters like semiconductors and communication systems (one had an error). Questions from mechanics part were a bit tricky and you needed to understand the language well before answering it. One question from mechanics was even taken from a previous year IIT-JEE paper. As far as optics and waves are concerned, the questions were relatively easier as they required few basic concepts and the “not so popular” formulae. Electricity and Magnetism was an easy section with error in one question but CBSE may give only one answer for it. The paper spanned almost the entire syllabus, and almost all topics had representation.
Overall score of 70-80 would be good.

Chemistry:

According to most, Chemistry was the easiest among the 3 subjects. However, compared to last year, the difficulty level of Chemistry is similar. The topics were evenly distributed in this subject. In Chemistry section, Physical Chemistry formed 40 per cent of the total questions. Questions from Inorganic and Organic Chemistry contributed to 33 per cent and 27 per cent respectively. The percentage of questions covered from Class XI and XII syllabus is 43 and 57 respectively. Many questions were memory-based. Good or rather tough questions were asked from memory-based topics like Biomolecules and Surface Chemistry. Questions from Inorganic were pretty easy. Organic chemistry was more focused on reagents involved in the reactions rather than final product. There was also the one customary question on name reactions. Physical chemistry could be considered as easy overall, with the exception of a few questions based on stoichometry where one had to know the reaction beforehand and some calculative questions. Reportedly, there was an ambiguity in one of the questions, where the full form of BOD was asked, with candidates reporting 2 answers to be correct instead of just one.
Overall score of 70-75 would be good.

The JEE Main results are out now. On an overall basis, the paper can be considered tougher than the one held on 3rd April.
