Hi,

My answer would be a BIG YES. You can crack IIT JAM in 3 months. If you remember all those stuffs that you studied in 1st and 2nd year then it should even take more less time.

“IIT JAM Success Mantra” that contains all the tips and tricks along with expert advice, book recommendations for various subjects, scopes after exam and complete self preparation guidance.

The most important thing that is needed for IIT JAM MA exam is really good knowledge of the basics.

For maximum of ones month, study the mathematics of +1 and +2. This will give you a strong foundation of really useful formulas.

Next thing you need to do is study Real analysis and Linear Algebra, most of the questions are from these two topics. Don't go for really fancy named books, they're not necessary for IITJAM. Stick to the books that are recommended in your college course, as they're made by keeping in mind about the topics and details that are actually needed .

Next go for functions of one and two variables as the questions from these topics are really easy. I'll suggest the book by Tom Apostol.

Then comes the most scoring topic - Differential Equations. You should be so thorough with this topic so that you can solve all problems without any sweat. Everyone will be able to solve Questions from this topic so you should be sure that you don't lose marks over here. Any book with basic Differential Equation is good.

Vector Calculus and Integration : most average student just leave this topic, as it takes a lot of time to solve. Practice them as much as you can , also visualization of the problem will be the key to solving them. I had studied this topic from the book named Calculus and Analytical Geometry by Thomas and Finney.

Hope this helps.

All the best.
