What is the NEET Exam?

Students in India who intend to pursue MBBS (Study of Medicine) or BDS (dental study) have to sit for a common entrance examination, now known as NEET (National Eligibility Cum Entrance Test). It was formerly known as the All India Pre-Medical Test (AIPMT). NEET is a 3-hour examination where candidates have the option of writing the examination in any of the 11 languages (English, Hindi, Bengali, Assamese, Oriya, Gujarati, Marathi, Tamil, Telugu, Kannada, and Urdu). 

Questionnaire structure for NEET

The primary subjects on which the 720 marks question paper is set are Physics, Chemistry, and Biology. Candidates have 180 questions to answer in total where 90 questions are from Biology and Chemistry and Physics have 45 questions each. When answering a question correctly will get the candidate 4 marks, answering one incorrectly will get a negative marking of -1.

NEET Qualifying Marks

Like all examinations, NEET too has qualifying marks or cut off marks for General, OBC, SC, ST, and PH. Though all candidates have to pass the qualifying examination (all the subjects individually), there are a few categories based on which the qualification marks are set for the candidates and they are:-

General, ST, SC, OBC, PH.

  • General Category- Candidates

under the general category must obtain 50% marks in the exam to qualify.

  • SC, ST, OBC- Candidates under the Scheduled Caste (SC), Scheduled Tribes (ST), and Other Backward Caste (OBC) must obtain a minimum of 40% marks in the qualifying exam.
  • PH- Candidates under the General category with a Physical disability (Physically Handicap category) will have to obtain a minimum of 45% whereas, candidates under the SC, ST, OBC with Physical disability will have to obtain 40% marks in the qualification exam.

Tie-Breaker

When there are two or more candidate who has scored equally then are certain tie breakers taken into consideration and they are:-

  • Candidates in NEET 2021, who have scored higher in Biology subject, will be given higher priority.
  • Candidates in NEET 2021, who have scored higher in Chemistry subject, will be given higher priority.
  • Candidates in NEET 2021, whose number of wrong attempts are less in comparison to the other in all subjects.

However, even after considering all the above-mentioned rules if there is still a tie then the candidate who is older in age will be regarded.

NEET Exam Fees

Candidates under the General Category will have to pay a fee of 1500/- whereas, candidates under the EWS/OBC (NCL) will have to pay a fee of 1400/- and candidates under the SC/ST/PwD/PH/Transgender will have to pay a fee of 800/-.
