How to Prepare for NCERT CBSE Class 12 Physics?

  • Try to give answers using pictorial or graphical representations as this way is more appealing and understandable.

  • Students are advised to practice numerical and derivations daily. As the basic concepts must be clear for scoring high

  • Candidates should learn the S.I units for all physical entities. This will make it easy for them to solve numericals.

  • Prefer making a list of derivations, formulae, and experiments so that students may go through them frequently. This will help them to remember the formulae well.

  • While solving a derivation, try to understand the logic behind them. Understanding the concept behind the derivation will help the candidates to broaden their technical knowledge.

  • After finishing the syllabus, students must solve questions from CBSE 12 sample papers and from books like Exam Idea in Physics.
