NEET Physics Notes for Quick Preparation & Revision
NEET Physics Notes help you prepare and revise faster all the important concepts and key formula in NEET Physics. Short and compact notes help us in quickly revising the concepts and formula periodically. The same is true for Physics also. The physics concepts and formulas of class 11 also you need to prepare for NEET along with the concepts and formulas for class 12.
Class 11 Physics Notes for NEET, you should also revise during your summer breaks after plus one. This would help you recapitulate the entire physics of class 11. While you study and prepare for NEET physics for class 12, you should not lose sight of class 11 physics. That’s why it is important that you have all the Physics NEET Notes, both for class 11 and class 12 handy and in a crisp and short format so that you can revise it often.
Making notes is a time-consuming exercise. At the same time, one needs to be thorough while making these physics study notes, lest one might miss on any important concept. The task becomes more complicated when you refer many extra books to grab that extra bit of knowledge from the best physics books for NEET. Either your notes become scattered on a topic across multiple pages or if you are in the habit of underlining in the books, then again these important notes are scattered across different books, class notes and tutorial notes.
Short but Comprehensive Notes
We, at CareerOrbits deeply understand the needs and extreme shortage of time at the disposal of the students preparing for NEET. At the same time, the need to revise the notes cannot be over-emphasised. So, the team of experts have done all the hard work for you and have put together the important concepts, the key formula with illustrations and diagrams in these Physics Study Notes as per the latest NEET syllabus. These Physics Study Notes are so designed that students are able to revise a chapter in two hours to six hours depending upon the depth of the chapter. This is a great time saving for all those students who are preparing for NEET. You have prepared the Physics chapters from your school textbooks but you still need to revise it often. This helps you save a lot of your valuable time.
Deeper Learning with Interactive Smart Notes
These study notes for NEET Physics might appear to be short to you but these enable deeper learning wherever you need to. With the passage of time, we tend to forget some concepts or probably need to quickly refresh our understanding of some concepts selectively. To your extreme delight, we have highlighted all those concepts, those important key concepts used anywhere in these study notes for NEET Physics. If you think you are not able to recall any particular concept in Physics or have a faint memory of that concept, you just need to move your cursor over that concept. In the first stage, you get an instant popup where the definition and key formula of that concept are mentioned. In most cases, this should help you refresh your memory. And in case, you still feel like studying that concept in detail, you can click on the Read More option and get the complete study note right there and then with illustrations. This is a boon for the time-starved students preparing for NEET.

Mastering NEET Notes is not enough to Crack NEET
Most NEET students would commit the serious mistake of preparing Physics as a theory subject. They would memorise the concepts and mug up the formulas. No matter how much you have memorised the concepts and formulas, you would not be able to perform well in Physics, unless you have mastered the application of these Physics concepts. Don’t miss to check out our other blog on NEET Physics MCQs or NEET Physics questions and learn how to perfect your application skills and problem-solving abilities.
Time management for NEET Physics
Having been equipped with the knowledge, conceptual understanding, formulas, application skills and problem-solving skills, now is the time to develop time management skills for Physics. Time management is crucial for Physics. Most of the students spend as much as 50% of their exam time on solving physics questions. The result is that they are not left with time to take on Chemistry and Biology with a cool mind. You should take the NEET Physics Chapter Tests and NEET Physics Mock Tests to be able to learn time management during the exam.
Other Subjects Notes for NEET
You would also need to have equally power-packed notes for the other two subjects to be able to crack NEET. Here are the links for NEET Biology and Chemistry preparation.
NEET Physics preparation:
- Use the physics notes for quickly preparing the concepts.
- After that, you can practice the physics questions for NEET in the Question bank.
- Then take the physics chapter tests for each chapter.
- Finally, attempt the physics full syllabus tests.
NEET Biology preparation:
- Use the notes for NEET biology to quickly prepare the concepts.
- After preparing the topics, you can practice the NEET level biology questions for each chapter.
- Then take the chapter tests for each biology chapter.
- Finally, attempt the biology full syllabus tests.
- Use the NEET Chemistry notes for quickly preparing the concepts.
- After that, you can practice the questions in the NEET Chemistry Question bank.
- Then take the Chemistry chapter tests for each chapter.
- Finally, attempt the chemistry full syllabus tests.
