About IIT JAM Chemistry

IITs and IISc are institutions of national importance and are well known, the world over, for quality education in engineering, science & technology and research in frontier areas. The aim of IITs and IISc is to build a sound foundation of knowledge, pursue excellence and enhance creativity in an intellectually stimulating environment. The vibrant academic ambiance and well-equipped research infrastructure of IITs and IISc motivate the students to pursue Research and Development careers in frontier areas of basic sciences as well as interdisciplinary areas of science and technology.

Joint Admission Test for M.Sc. (JAM) is being conducted from 2004 to provide admissions to M.Sc. (Four Semesters), Joint M.Sc.-Ph.D., M.Sc.-Ph.D. Dual Degree, etc. Programmes at the IITs and Integrated Ph.D. Degree Programmes at IISc for consolidating Science as a career option for bright students. These postgraduate programmes at IITs and IISc offer high quality education in their respective disciplines, comparable to the best in the world. The curricula for these programmes are designed to provide opportunities to the students to develop academic talent leading to challenging and rewarding professional life.

Eligibility Criteria

The candidates who qualify in JAM 2020 shall have to fulfill the following Eligibility Requirements (ER) for admissions to IITs.

  • All candidates admitted through JAM should have a Bachelor’s degree.
  • In the qualifying degree, the aggregate marks or CGPA/CPI without rounding-off (taking into account all subjects, including languages and subsidiaries, all years combined) should be at least 55% or 5.5 out of 10 for General/OBC (NCL)/EWS category candidates and 50% or 5.0 out of 10 for SC/ST and PwD category candidates.

If CGPA/CPI is on a different scale, it would be linearly mapped to a scale on 10.

At the time of admission, all admitted candidates will have to submit a Physical Fitness certificate from a registered medical practitioner in the prescribed form. At the time of admission, the admitted candidates may also have to undergo a Physical Fitness test by a medical board constituted by the Admitting Institute. In case a candidate is not found physically fit to pursue his/her chosen course of study, his/her admission is liable to be cancelled.


  1. It is entirely the responsibility of the Candidate to prove that he/she satisfies the Minimum Educational Qualifications (MEQs) and Eligibility Requirements (ERs) for Admission.
  2. The Admitting Institute has the right to cancel, at any stage, the admission of a candidate who is found to have been admitted to a course to which he/she is not entitled, being unqualified or ineligible in accordance with the rules and regulations in force.
