### NDA Physics Preparation 2021

To prepare for the Physics section, you should clear all your concepts and get practical knowledge of Subject. Some of the preparation tips for this section of NDA 2017 are given below:

1. Overcome your Physics Phobia: Many students who are not so good at Mathematics think that physics is also difficult. This negative thinking should not be there as it becomes the biggest hurdle in the path of success.
2. Physics is not like Mathematics: Candidates may be weak in Mathematics but this should not stop them from succeeding in Physics section. For example- some topics from Optics, Modern Physics including Electronics hardly require higher mathematical skills or knowledge. You can perform well in these kinds of units.
3. Take interest in the Physics section: Unless you take interest in it even if it has very less weight-age, you will not be able to succeed even after doing lots of hard work.
4. Physics is not limited to Numericals only: Many students avoid Physics section thinking that it is loaded with only numerical. To a certain extent, numerical problems are in almost every chapter of this section. If you find it tough, leave the numerical section and proceed ahead, prepare for other sections. Study theoretical portions properly with all basic concepts understood.
5. Formula learning: Learn all Formulas thoroughly and revise them regularly. Try to solve 5-10 numerical problems based on the learned chapters daily. Consult your teachers and friends for any kind of help. You can also participate in group discussion and give online mock tests.
6. Ohms Law” is a very important unit for this exam. In NDA it has the highest weight-age. Never neglect this unit. Chapters like Mass, Force, and Momentum should be prepared from the very beginning.
7. Study for the Physics section regularly: While preparing for Physics you should not learn a chapter today and then leave the subject unattended for the next 2 to 3 days. Instead, after going through a chapter, practice different types of numerical from it. At least an hour of regular self-study is must for the better preparation of Physics section.
8. Go through previous 5 to 10 years solved question papers. You will get an idea about the question pattern and exam pattern as well. It will also help you in shortlisting important questions. Solving sample papers will boost your preparation tremendously at a very fast pace.
9. Revision is probably one of the most crucial and important steps to get good results. Keep revising chapters and formulas to avoid forgetting them. It will help you significantly in the test.
10. Start your preparation from today itself. Try to complete your syllabus till February. You must avoid last month preparation.

### NDA Recommended Books for Physics

If you check the syllabus and marks for the Physics section, it shows clearly the weight-age and importance of this subject. Check the previous years solved papers for NDA exam.

You may consider using:

• Quick learning Objective General English by RS Aggarwal &  Vikas Aggarwal.
• Keep yourself updated and buy Manorama Yearbook (English), and read it cover to cover.

Also, practice previous years NDA Tests’ sample papers

#### Books for Previous Year Solved Papers and Practice

Use NCERT textbooks and other books for revision. Some advisors strongly suggest buying one of the books given below as they have been specially designed for NDA exam and cover previous years solved questions and practice papers.

• Pathfinder for NDA & NA Entrance Examination (English) by Arihant Publications
• Chapter-wise – Section wise Solved Papers NDA & NA (Mathematics/English/General Ability) by Arihant Publications
• NDA Examination (Solved papers up-to-date) (English) by Upkar Publications
• NDA/NA Previous Solved Papers (English) by RPH Editorial Board
