**Know the exam pattern and syllabus**: Candidates must know the exam pattern and detailed syllabus for JEE Main before kick-starting the preparation. By going through the JEE Main syllabus, they will understand which subjects and topics are used in questions. Candidates can then segregate questions on each chapter and unit from previous years JEE Main question papers. - ●
**Choose the right books**: Considering the vast syllabus for JEE Main, it is important that candidates choose the right selection of books to ensure that they cover all the topics well. The following section provides a list of books recomended by IIT toppers for JEE Main preparation across each subject.

**Time Management**: To ensure thorough coverage of the syllabus, candidates must divide their time effectively. This will also help them to have enough time for revision. Aspirants must maintain a strict daily routine and avoid random or weekend preparation sessions. Dividing sections as per the time in hand each day to plan study hours will lead to effective time management. Going through analysis of previous years' JEE exam will help candidates to create a study-plan which targets the most important areas of the exam. - ●
**Prepare notes/flashcards**: While preparing, aspirants should create flashcard and short notes for important concepts/formulae which will help them save time a month before the main exam as the candidates can quickly go through these short notes for revision. - ●
**De-stress**: While preparing for one of India's toughest examinations, stress might make you feel worried and nervous. It is advisable to include stress busters in your daily preparation time table. Stress reduces productivity therefore when you feel stress creeping in, take a small break- a walk in a park, watching your favourite movie, playing a sport or game. These destressing time-outs will help aspirants to overcome anxiety and make them feel fresh and energetic to continue their preparation and write the examination. - ●
**Practice JEE Main sample papers and previous year question papers**: Solving sample papers and previous-year papers helps candidates assess their level of their preparation. Practicing these JEE Main sample papers will help candidates know different aspects of the exam - questions which are very difficult for them and those which are either moderately difficult or easy. Attempting these sample papers will enlighten candidates about the areas in which they need to put in more effort and subjects where they can build confidence about their preparation. - ●
**Attempt Mock Tests to get familiar to actual examination conditions**: Candidates are advised to attempt JEE Main mock tests from 9:00 a.m to 12:00 p.m and from 2:00 p.m to 5:00 p.m. This will help make candidates comfortable for the D-day of JEE Main exam as they will be able to acclimatise themselves and not face any problem on the day of the actual exam. - ●
**Revision**: To brush up their concepts before the exam, candidates should keep at least one month or two for revision. Revision at this stage should be quick and candidates should use the short notes that they make during preparation for this purpose.

Citizens of India, foreign national candidates as well as NRIs, PIOs, OCIs can apply for the exam

There is no age limit for candidates who wish to appear for JEE Main 2020. IITs can set age criteria for admissions, which should be reviewed in the JEE Advanced 2020 Information Brochure

Candidates should have cleared their class 12th board exam or any equivalent exam listed by NTA in 2018 or 2019. Candidates who are appearing in their class 12th examination in 2020 are also eligible to appear in JEE Main 2020

Candidates must secure 75% Marks in class 12 board exams or be within the top 20 percentile of their respective boards for admissions in NITs, IIITs and GFTIs. For reserved category candidates, the minimum percentage is 65%

Candidates should have passed the qualifying exmaination with Physics, Mathematics and Chemistry/Biology/Biotechnology/Technical Vocational Subject for admission to B.E./B. Tech courses. For admission to B. Arch, candidates should have passed the qualifyinf examination with Physics, Mathematics and Chemistry while for B. Plan only Mathematics is a mandatory subject

Candidates can appear for JEE Main for three consecutive years, irrespective of session attempts since two attempts in a year will be considered as one

The result for Paper 2 & 3 in January session of JEE Main 2020 was released by the National Testing Agency (NTA) on January 23 while the result for Paper 1 was declared on January 17. Candidates must enter their Application Number and Password/Date of Birth to view the result and their percentile score. NTA will not dispatch JEE Main 2020 scorecard through mail or post to aspirants who appeared for the exam. This year, the process of normalisation has been used to determine the JEE merit list. As per the official notification, the total number of candidates registered for B.E. /B. Tech. were 9,21,261 and number of candidates appeared were 8,69,010.

The result date for the April session of JEE Main 2020 is yet to be be announced. The NTA scores for JEE Main 2020 Paper-1, 2 and 3 for both the sessions will be merged to prepare the JEE Main 2020 merit list. The best of the two NTA scores will be considered for further processing for candidates who have appeared for both the sessions.

In case two or more candidates secure equal percentile scores in JEE Main 2020 result, then the ranking will be determined using the below mechanism:

**JEE Main 2020 Tiebreaker for Paper 1(BTech):**

- ●NTA score in Mathematics: Candidate who secures more percentile score in Mathematics will be ranked higher
- ●NTA score in Physics: Candidate who secures more percentile score in Physics will be ranked higher
- ●NTA score in Chemistry: Candidate who secures more percentile score in Chemistry will be ranked higher
- ●Date of Birth: The older candidate will be ranked higher
- ●In case the tie still stands unresolved, the same rank is given to the candidates

**JEE Main 2020 Tiebreaker for Paper 2 (BArch):**

- ●NTA score in Mathematics: Candidate who obtains higher marks in the mathematics will be given a higher rank
- ●NTA score in Aptitude Test: Next, if the tie still persists, then aspirant with a higher score in the aptitude test will be allotted a higher rank
- ●NTA score in Drawing Test: If the tie still persists, then aspirants with higher scores in the drawing test will be allotted a higher rank
- ●Lesser negative response: Candidates having lesser number of negative responses in the paper
- ●Date of Birth: The older candidate will be ranked higher

**JEE Main 2020 Tiebreaker for Paper 3 (BPlanning):**

- ●NTA score in Mathematics: Aspirants who obtain higher marks in the mathematics will be given a higher rank
- ●NTA score in Aptitude Test: If the tie still persists, then aspirant with higher scores in the aptitude test will be given a higher rank
- ●NTA score in Planning Based Questions: If the above criteria do not break the tie, then the candidate will higher marks in planning based questions will be given the higher rank
- ●Lesser negative response: Candidates having lesser number of negative responses in the paper
- ●Date of Birth: The older candidate will be ranked higher

After the declaration of results for both JEE Main and JEE Advanced, JoSAA conducts joint seat allocation process for admissions to 100 institutes including 23 IITs, 31 NITs, 25 IIITs and 28 Other GFTIs. Admission to all the participating institutes will be done through a single counselling platform.

JEE Mains Cutoff 2020 will be released by the National Testing Agency (NTA) after the declaration of result. The cut off will be of two types– qualifying cut off marks and admission cut off. The qualifying cut off will be the minimum score that JEE Main 2020 aspirants need to secure to be eligible for JEE Advanced. Therefore, only those candidates who meet JEE Main qualifying cut offs will be eligible for admission to IITs in India.

The admission cutoff will be released by JoSAA (Joint Seat Allocation Authority) in the form of opening and closing ranks for each institute. Admission cutoffs of the participating institutes will be released after each round of JoSAA counselling and candidates who achieve a rank within the closing ranks will be eligible for admission to JEE Main participating institutes.
