The JEE Mains exam 2017 saw registration of a record 1.40 million candidates, out of which, about participation fared around 1.26 million for the Offline Paper 1 JEE Mains Exam 2017 conducted on April 2, 2017.
The Pen & Paper JEE Mains exam 2017 was conducted across 150 centres. The Online JEE Mains exam will be held on April 8, 2017 across designated centres in the country. The expected JEE Mains Result 2017 is expected to be out towards the end of April 2017. The cut off for qualifying 2017 JEE Advanced will also be declared on the same day based on the result of JEE MAINS 2017.
As per academicians and experts, JEE Mains 2017 turned out to be moderately easy. The paper, however, was deemed lengthy, with many questions being lengthier than JEE Mains 2016.
The difficulty level of JEE Mains varied from subject to subject. Chemistry turned out to be the easiest of the lot with more than 50% questions had be solved with a direct approach. On the other hand, Maths had a mix of easy and difficult questions. Physics had easy to moderate questions as well as tricky questions. A subject-wise break-up of the paper is given below:
| Subject | Easy | Medium | Difficult |
|---|---|---|---|
| Chemistry | 10 | 16 | 04 |
| Physics | 11 | 12 | 07 |
| Mathematics | 08 | 17 | 05 |
| Total | 29 | 45 | 16 |

The normalized qualifying examination marks for JEE will be based on the student’s performance in the Board exams (i.e. his/her percentile score). The percentile score of the Boards will mainly contribute to his/her normalized marks. The weightage of normalized qualifying examination marks is only for deciding ranking of JEE (Mains) which will be used for admission to all Centrally Funded Technical Institutions (CFTIs)/ NITs/IIITs but excluding IIT's.
