Dear student,

Within 2 months it is very hard to cover all the syllabus, but it is not impossible. But in my viewpoint, rather than completing all the syllabus you should study only some selected topics. And studying these topics will be enough to get around 150-160 in the JEE Mains exam . So, below I am listing some very easy and very important topics for both the three subjects.

Physics :

EM Waves, Semiconductors, Errors, Optics, Photoelectric effect, current electricity, optics, gravitation, EMI and ac, waves, magnetic effect, rotation

Chemistry :

S, p , d ,f block elements, isomerism, nitrogen compounds, chemical kinetics, solid state, carboxylic acid, biomolecules , polymers, hydrocarbon, metallurgy, solid state, mole concept, equlibrium

Mathematics :

matrix , determinants, area under the curve, integration, differentiation, straight lines, circles, vectors, 3d,  probability, complex no., quadratic eqn, functions, ITF , conic sections

Alongwith that, you must solve as much previous year papers as you can. This will be very helpful.

Hope it helps.
