How to prepare Physics for IIT JAM

How to prepare for IIT JAM Physics

Joint Admission Test(JAM) is an all India admission test conducted jointly by the Indian Institute of Technology(IITs). This exam is to get admission in IITs for M.Sc.,integrated Phd and M.Sc.-Phd dual degree. It was first conducted in 2004. Every year approximately 10,000-11,000 students appear for Physics in this exam. Precisely defined syllabus of this exam makes it easier to qualify the cut off, but for better result or to get admission into IITs you need good score. Here in this post I am going to discuss on "How to prepare Physics for IIT JAM".
   So let us have a look on syllabus which makes many things clear that what to read and what to leave.

  • Data analysis of previous year Physics question paper for IIT JAM 



Data about number of questions in Physics for IIT JAM
Image showing data of all previous year questions



Let's analyse some previous year question papers, because it is very important to know how much gravity a topic carries. So it will help you to make a better strategy for each topic.


Graph on number of questions in Physics for IIT JAM(last two years paper)

Graph on number of questions in Physics for IIT JAM(last five years paper)


As we can see from the above pie chart which are showing that by covering topics electricity and magnetism, mathematical physics,modern physics. mechanics, thermal physics your 74-75% of job is done and if you can do it well then you can crack the exam for sure. To get admission in IITs, a general category candidate need 36-40 marks out of 100. Now you have two choices one is waves and optics and other is electronics. Both are equal important. But I will suggest to go through  waves and optics portion because it has some advantage over electronics portion as the concepts are very familiar to us which we had read in 11th and 12th standard. So it will be unfair to leave it as questions from waves and optics are usually formula based and tricky a little bit.
   Quality study material is very important, so I am going suggest some books which I hope, will help you a lot.
