JEE Main, JEE Advanced 2021 exam dates, other important announcements made including some relaxations in eligibility criteria for admission in IITs

 9-Jan-2021

Update 18-April-2021: JEE Main 2021 April session exams postponed due to rising Covid-19 cases  

JEE Main 2021 JEE Advanced 2021 - Exam Dates, Eligibility Criteria and Other Important Changes

• JEE Advanced 2021 exam will be organized by IIT Kharagpur and held on July 3, 2021.

• Until 2020, students were required to score either minimum 75% in Class 12 Board Exam or be among the top 20 percentile in their board exams, in addition to qualifying the IIT Advanced exam, to get into any of the 23 IITs. From 2021 this eligibility criteria of 75% marks in Class 12 Board Exam has been removed for the convenience of students.

• On December 16, the education minister had announced that the JEE Main 2021, conducted by the National Testing Agency (NTA) will be held four times a year in February, March, April and May. The first slot of JEE Main is from February 23-26, 2021. The next sessions of the exam will be held between March 15-18, April 27-30 and May 24-28.

• Students will be given a choice to answer 75 questions (25 each in Physics, Chemistry and Mathematics) out of 90 (30 each in Physics, Chemistry and Mathematics). Merit list/ranking will be prepared based on the best score of the candidate.

• Here this can be recalled that JEE Main is the exam for entry into undergraduate engineering courses. Those who will qualify in this exam can appear for the JEE Advanced which is the entrance examination for admissions into the IITs. The examination will be held in 13 languages including Hindi, English, Bengali, Assamese, Marathi, Tamil, Odia, Telugu, Kannada, Urdu, Malayalam, Punjabi and Gujarati.

Will NTA conduct NEET twice a year | How many times one can appear in NEET

 26-Oct-2020

NEET FAQs 

Doubts, Confusions about NEET (National Eligibility-cum-Entrance Test)

Will NTA conduct NEET twice a year ?

How many times NEET exam is held in a year ?

Will neet be conducted two times in 2021 ?

Answer:

Please be informed that till 2020 NTA used to conduct National Eligibility-cum-Entrance Test (NEET) once in a year with more than 71,000 undergraduate seats i.e. MBBS admissions across the country.

However, MBBS admissions in AIIMS and JIPMER which until 2019 were done through their own separate exams will this year be based on NEET 2020 scores followed by counselling. Implementation of the NMC Act and cessation of both AIIMS MBBS and JIPMER MBBS exams have created a greater demand for NEET which may ultimately force to conduct the NEET examination twice a year in future. NTA has already received various proposals and suggestions that the exam be conducted twice a year.

AIIMS MBBS was tougher than any other medical entrance test in India. To maintain the standards of the Institution, NTA has been advised by several experts to focus on the pattern of the NEET question paper. Expecting an increase in the difficulty level of the examination, various student bodies have requested NTA to increase the frequency of the examination to twice a year, like JEE Main, to enable them to pick the best score of the two exams.  So, there are some discussions and planning going on at primary level and frequency of NEET may be increased to twice a year from the academic session 2021-2022 for which the confirmation is yet to come. However, this would be possible only after the final nod from the central health ministry.  

Nevertheless, there would be certain benefits as well as difficulties of conducting or appearing NEET twice in a year. (If you want to know about this, please let us know in the comment section. We can discuss about the various pros and cons of having NEET twice in a different post).

Is there any restriction of number of attempts in NEET exam ?

How many times one can appear in NEET ?

Answer:

There is no such attempt limit in NEET till 2020, only age limit is applicable.
