AIIMS MBBS 2020 Exam Pattern

The AIIMS MBBS Exam Pattern will be slightly different now as the AIIMS Entrance Exam has been now merged with NEET. Thus, the changes that will come into play are as follows:

  1. The Exam will take place in offline mode, i.e it will be a pen and paper-based test.
  2. Candidates will further have to complete the exam in 3 hours.
  3. There will be 180 questions in total
  4. The exam will be of 720 marks
  5. The Questions are Multiple Choice Objective Questions.
  6. For each correct answer, 4 marks will be awarded.
  7. In addition, negative marking is applicable. Hence, 1 mark will get deducted for each incorrect answer.
  8. Further, there will be 3 sections in the paper, i.e Physics, Chemistry, and Biology (Zoology & Botany). Wherein, the Physics and Chemistry section contains 45 questions each. Moreover, 90 questions will be there in the Biology section (Zoology (45) + Botany (45)).

AIIMS MBBS Result 2020

The AIIMS MBBS Merit List Result will be released within a week or two after the entrance exam. It will be released in online mode and hence will be available on the official website. Candidates’ can direct check the NTA Website to check their results. However, it will be available on the website of AIIMS as well. The exams have been merged and it’s going to happen for the first time, so we will see how things go. Furthermore, the result will be declared in the form of a merit list. Wherein, the students will be ranked in order of merit. The AIIMS officials may also release a separate merit list for indicating the names of students eligible to get admission in this medical institute.

AIIMS MBBS 2020 Counselling

Counselling will be the last and final round of the admission process. Only the merit list students will be eligible to take part in this admission round. The date, time and venue details of AIIMS MBBS Counselling 2020 will be available on the official website as well. It is further compulsory for all students to take part in the counselling round. Candidates failing to do so will lose out their seats to other deserving candidates. Moreover, the procedure of seat allotment and document verification will be carried out on the same day. The students should thus carry the photocopies and originals of the relevant documents. Further, on the basis of this round, the seats will be allotted to the students.
