The Joint Entrance Examination is a national level engineering entrance exam held twice a year for admission into various engineering colleges in India. The National Testing Agency conducts it.
Joint Entrance Exam is formed by two separate exams- JEE Main and JEE Advanced.
The Joint Entrance Examination (JEE) is a national-level computer-based engineering entrance exam conducted by NTA (National Test Agency) for admission to various colleges in India, such as Indian Institute of Technology, National Institute of Technology, Indian Institute of Information Technology and other Government funded technical Institutes.
IITs, NITs, IIEST, IIITs and other GFTIs. Please note that for admission in IIT, a candidate has to pass JEE Main + JEE Advanced.
JEE Mains comprises of two papers, Paper - I and Paper - II. Candidates can choose either of the two. Both papers have multiple-choice questions. Paper - I is for the admission in B.E./B.Tech courses. Paper - II is for the admission in B.Arch and B.Planning courses.
Candidates can choose either of the two.
JEE Main 2023 Session - 1 exam done on 24, 25, 27, 28, 29, 30 and 31 January 2023. JEE Main 2023 Session - 2 Exam Dates are 6, 8, 10, 11 and 12 April 2023.
The validity of the result is one year.
All Candidates will not get the same sets of question papers.
The normalization process is an established practice prescribed by NTA for comparing candidate scores in multi-session papers adopted in other large academic selection tests conducted in India. In simple terms, it ensures that no candidate is at any loss or may even get benefit from this procedure.
1. if the candidate is acquiring equal marks/percentile, then among themselves merit will be determined to below sequence :-
(a) Candidate acquiring higher marks/percentile in Maths.
(b) Candidate acquiring higher marks/percentile in Physics,
(c) Candidate acquiring higher marks/percentile in chemistry,
(d) Candidate who is older is preferred.
2. The final ranking will be done after the tie is resolved.
5 steps need to be followed to fill the registration form 1. Fill online form, 2. Upload documents, 3. Select the exam centre, 4. Payment & 5. Submit.
JEE Main 2023 exam has been conducted in 290 cities in India and in 25 cities outside India and over 8.22 lakh candidates have appeared in the exam.
