APPROACH TO IITJAM PHYSICS-2016


 IIT JAM is a joint admission test conducted by IIT’s and IISc for admission into M.Sc, Integrated PhD, M.Sc-PhD dual degree, Joint M.Sc-PhD courses. In the last few years, this exam has become gateway for many other institutes also. Last year, many NIT’s have started taking admission into its M.Sc. courses based on IIT JAM score. Many IISERs are also taking admission based on JAM score. So, the most important question is how to prepare for this prestigious exam. The IIT JAM syllabus consists of mainly seven topics- Mechanics, Electricity and Magnetism, Modern Physics, Mathematical Physics, Oscillation, Waves and Optics, Thermal Physics, Solid State Physics and Electronics. Given the poor state of University education, students find this exam pretty hard to crack. Students face difficulties in solving numericals since, during graduate courses, the stress is mostly on theory and derivations. Since, IIT JAM paper is mostly a numerical paper so, we have to understand the concepts by solving numericals. If you see the topic wise weightage for the last eleven years, we find that the Mechanics, EM and Modern Physics consist of the major chunk of the paper (51.7%). They are followed by Solid State and Electronics, Thermal, M.P. and Oscillation, Waves and Optics. While you do these topics you must stress on the things which are taught at graduate level. You should start will Electricity and Magnetism. Do this topic well. In this topic most important chapters are polarization of dielectrics, Work and energy in Electrostatics, Ampere’s law, Faraday Law, DC-Circuit, EM Waves. After doing this, you should do mechanics where you should put stress on central forces, Coriolis forces, collision, centre of mass, rolling and angular momentum, MI tensor, Bernoulli Principle. Try to be selective in mechanics otherwise it will consume lot of time. Then you should go for mathematical physics. The important topics in M.P are linear differential equation of first order, Gauss, Green & Stokes theorem, eigenvalues and eigenvectors, partial derivatives, Fourier series. After this go for modern physics which is very sweet topic as it will take less time to prepare and very rewarding. Do not leave anything is this topic. The next topic you should go for is oscillation, waves and optics where you should focus on interference, diffraction and polarization more. In thermal physics, you concentrate on PV, PT, VT, TS diagram, Maxwell relations and Maxwell Boltzmann statistics. At last you should go for solid state physics & electronics. In solid state physics, Miller indices, Bragg’s law and semiconductors are very important. In electronics, Zener diode, BJT and Op-amps are very important.At last, I would advise you that overall approach of your preparation should be exhaustive because paper contains objective questions and NAT questions and these questions can be created from anywhere. I have only pointed out important areas. The last thing is that you must also do subjective question while preparing these topics, because that will help you in building you concepts. Moreover, the NAT questions of two marks are like short subjective questions. Refer to all Samvedna books, they have been written keeping you in mind and these books will help you in other entrance exams also. I strongly recommend you TRAJECTORY DVD lectures and Online tests.
You should go for online test only as JAM is online now.
Best of luck for your preparation
