Preparation Tips for Physics Syllabus

Preparation Tips for NEET Physics Syllabus

We have devised the perfect study plan and preparation tips for you to crack NEET Physics.

  • Tip 1- Check the syllabus and exam pattern: Checking the NEET Physics syllabus and exam pattern is the very first step for your exam preparation. You will also need to be aware of the physics section marking scheme in NEET.
  • Tip 2- Gain clarity on important concepts: The most important topics in NEET Physics, according to previous years’ papers are - Mechanics, Heat and Thermodynamics, Electrodynamics and Modern Physics. You must first clearly understand the concepts relevant to these topics for your physics study plan. Once that is done, you can move onto other concepts.
  • Tip 3- Know all formulae: Formulae are the very core of Physics. The most critical step in preparing for NEET Physics is learning the formulae. You can use a little notebook to write all the formulae for NEET Physics. Ensure that you test your memory on these formulae every day.
  • Tip 4- Refer to the best NEET Physics books: You need to refer to the best physics books for NEET. NCERT is the best NEET exam preparation book. NEET follows the question patterns of NCERT. You can also use a few more books for thorough learning and practice.
  • Tip 5- Solve question papers of previous years: The best way to prepare for NEET Physics is to solve question papers of the previous years. Solving these NEET Physics questions will help you recognise NEET’s pattern of questions. Doing so will also increase speed and precision in answering. Make sure to answer as many question papers as you can.
  • Tip 6- Make notes: You must make notes of all the essential formulae, theorems and principles during your NEET Physics training. Physics notes for NEET will help you understand the concepts quicker, and will also help you plan for the last minute.
  • Tip 7- Take online mock tests: Taking online mock tests will help you determine how well you have studied for the exam. It will also help you recognise your areas of weakness.
  • Tip 8- Enhance the strength of your weak areas: Seek to strengthen your weak areas. Spend more time on the topics that challenge you the most. You have to prioritize NEET Physics' most important topics and then plan for the less important ones.
  • Tip 9: Video Lecture on NEET Physics by NTA: In order to help students prepare for an exam as competitive as NEET, NTA has released content-based videos. They have been made exclusively for NEET-UG and JEE Mains by IIT professionals or subject experts.
