In order to secure admission in IGIMS (Indira Gandhi Institute of Medical Sciences) or any government medical college in India, candidates must meet certain requirements and achieve a certain minimum score. Here is a detailed explanation of the admission process and the necessary marks to get admission:

1. Entrance Exam:
Admission to IGIMS and most government medical colleges is based on the scores obtained in the National Eligibility cum Entrance Test (NEET). NEET is a national level medical entrance exam conducted by the National Testing Agency (NTA) for undergraduate medical and dental courses.

2. Eligibility Criteria:
To be eligible for admission, candidates must fulfill the following criteria:
- Age: The minimum age limit is 17 years as of December 31 of the admission year. There is no upper age limit for NEET.
- Educational Qualification: Candidates must have completed their 10+2 or equivalent examination with Physics, Chemistry, Biology/Biotechnology, and English as compulsory subjects. They should have scored a minimum aggregate of 50% (40% for SC/ST/OBC candidates) in the PCB subjects.

3. NEET Cut-Off:
The cut-off marks for NEET vary each year depending on factors such as the difficulty level of the exam and the number of applicants. The cut-off score is the minimum qualifying marks required to be eligible for the counseling process. The cut-off marks are determined by the respective state's counseling authorities and the Medical Council Committee (MCC).

4. State Counseling:
After the NEET results are declared, candidates need to participate in the counseling process conducted by the respective state authorities or the MCC for All India Quota seats. The counseling process involves registration, choice filling, seat allotment, and document verification.

5. Merit List and Admission:
Based on the NEET scores and the choices filled during counseling, a merit list is prepared. Candidates are then allotted seats in IGIMS or other government medical colleges according to their rank and availability of seats. The admission process includes document verification, payment of fees, and completion of other formalities.

6. Reservation Criteria:
Government medical colleges follow reservation policies set by the respective state governments. These policies provide reservation for categories such as Scheduled Castes (SC), Scheduled Tribes (ST), Other Backward Classes (OBC), and Economically Weaker Sections (EWS). The reservation percentages vary from state to state.

By following these steps and achieving a competitive score in NEET, candidates can secure admission to IGIMS or any government medical college. It is important to note that the specific marks required for admission may vary each year depending on the number of applicants and the overall performance in the NEET exam.
