IIT JAM is one of the famous PG entrances for the admission to IIT's, NIT's and CFTI. If you wish to prepare for it the you need to at first visit the JAM 2022 website and then download the syllabus of the examination. Every year, the syllabus remains the same & based on the syllabus you have to prepare yourself.

The syllabus of Mathematics in IIT JAM contains three topics in itself, this are:

• Real Analysis
• Multivariable Calculus and Differential Equations
• Linear Algebra and Algebra

Now in your first year, you have completed any of the portions of this topics. Select those topics, and keep on reading up and preparing for it. The preparation will become a cake walk for you if you consider the previous year question of the IIT JAM as this will provide you some background to the question and theories you need to know. After completion of the portions you have already studied, try on learning the new topics (as per syllabus) from different open sources such as Youtube, and keep practicing from standard text books. This is the self study strategy. Now if you wish to take admission to some coaching then the course of Career Endeavors is quite good, you can consider that.

What ever you do practicing problems and attempting mock tests will be a prime concern for you.
