What is IIT JAM exam?
The Indian Institute of Science (IISc) is a premier research and teaching institute established in 1909. The IISc Bangalore and IITs are well-known, the world over, for quality education in engineering, science, management, and research in frontier areas.
These institutes aim to build a sound foundation of knowledge, pursue excellence, and enhance creativity in an intellectually stimulating environment.
From the Academic Session 2004-05, IITs started conducting a Joint Admission Test for M.Sc. (JAM).
There are many MSc entrance exams held across India and IIT JAM is the most popular among them.
In this post, we will see the IIT JAM Physics syllabus.

The pattern of IIT JAM Physics Test Papers
The JAM 2020 Examination for all the six test papers will be carried out as ONLINE Computer Based Test (CBT) where the candidates will be shown the questions in a random sequence on a computer screen.
For all the six test papers, the duration of the examination will be 3 hours. The medium for all the test papers will be English only.
There will be a total of 60 questions carrying 100 marks. The entire paper will be divided into three sections, A, B, and C. All sections are compulsory. Questions in each section will be of different types as given below:
Section–A contains a total of 30 Multiple Choice Questions (MCQs) involving 10 questions of one mark each and 20 questions of two marks each.
Each MCQ has four choices out of which only one choice is the correct answer. Candidates can mark the answer by clicking the choice.
Section–B contains a total of 10 Multiple Select Questions (MSQs) carrying two marks each. Each MSQ is similar to MCQ but with the difference that MSQ may have one or more than one correct choice(s) out of the four given choices.
The candidate gets full credit only if he/she selects all the correct answer(s) only and no wrong answers. Candidates can mark the answer(s) by clicking the choice(s).
Section–C contains a total of 20 Numerical Answer Type (NAT) questions involving 10 questions of one mark each and 10 questions of two marks each.
For these NAT type questions, the answer is a signed real number, which needs to be entered using the virtual numeric keypad on the monitor. No choices will be shown for NAT questions.
In all sections, questions not attempted will result in zero marks.
In Section-A (MCQ), the wrong answer will result in negative marks. For each wrong answer to 1 mark questions, 1/3 mark will be deducted and similarly, for each wrong answer to 2 marks questions, 2/3 mark will be deducted.
In Section-B (MSQ), there are no negative and no partial marking provisions. There is no negative marking in Section-C (NAT) as well.
There is a provision of using the online virtual calculator. The candidates, therefore, should not bring any calculator with them.
Mobile phones or any other electronic devices are strictly prohibited inside the examination hall. Charts, graph sheets, and tables are also NOT allowed inside the examination hall.
A scribble pad will be provided for rough work and this has to be returned back at the end of the examination.
The candidates are required to select the answer for MCQ and MSQ type questions using the mouse. The answer for NAT questions can be entered using a virtual numeric keypad (the keyboard of the computer will be disabled).
At the end of the 3 hours, the computer will automatically end the examination.
