NEET Cut Off

Candidate who qualify in NEET are eligible to take part in NEET counselling 2023. To qualify in NEET, students have to get minimum 50 percentile for UR and 40 percentile for SC / ST / OBC category.

NEET cut off 2023 is based on number of seats, previous years cut off, total number of candidates, and total number of qualified candidates. And there is a process to check NEET cut off 2023:

• Candidates must note down the question attempted and calculate their score by following the marking scheme: NEET Score = (no. of correct answers X 4) - (no. of incorrect answers X 1).
• Match your score with the qualifying cut off marks.
• If you have passed by doing above steps, then check the NEET cut-off of various colleges.

Category wise NEET Cut Off 2023

Category	Cut off Percentile	Cut off Marks
General category	50	701-134
OBC/SC/ST Category	40	133-107
General (PH) Category	45	133-120
SC/OBC/ST (PH) Category	40	133-107
SC & PH	40	133-107
ST & PH	40	133-107

NEET Previous Year Question Papers

With the help of previous years question papers of NEET, candidates will get familiar with NEET-UG 2023 exam pattern, types of questions and weightage of questions. NCERT is the best book for NEET Preparations-"75% of the questions asked in NEET are from NCERT books". NCERT and previous years question papers are also very helpful in clearing the NEET exam.

The questions given in the NCERT book helps students strengthen their previously studied fundamental concepts. The questions given in the NCERT book helps students strengthen their previously studied fundamental concepts. The primary objective of these question papers is to bring clarity about the process of linking the questions to the performance indicators and hence definitely the results.

By regularly practising the previous year's question papers, students will develop a better understanding of the concepts. All the previous year's question papers are in PDF format and easy to download.
