Important Topics

As we move further let’s talk about subject wise topics which are categorised according to their difficulty level.

Physics

Let’s talk about the important topics which come under Physics section preferring according to the frequency in which they were asked in JEE Main. These topics have been carrying a consistent weightage as per the JEE Main previous year papers.

Easy

  • Electrostatics: It is a lengthy topic but is an easy topic to study. Frequently every year 3-4 questions are asked from this topic.
  • Current Electricity: It is small but with a scoring topic. Questions are asked from this topic are like the colour code of resistors, Ohm’s Law, etc. are frequently asked in the exam.
  • Electromagnetic Induction and Alternating Current: 1-2 questions are asked from these topics.
  • Semiconductor & Electronic Devices, Communication, Units & Dimensions, Measurement of error (Absolute and Relative), Instruments: Can easily score 16-20 marks from these topics.
