How to Prepare for GATE Physics?
We have already discussed your first step in preparing for GATE 2021 that is going through the exam pattern, marking scheme, and syllabus of the exam. Your next step should be collecting all the relevant study material and start your preparation. All these steps should be taken in the first month of your preparation. Besides these, there are a few things that you should keep in you mind throughout your preparation. We have suggested a few tips that can follow which will surely help you prepare well and bring impressive results.
You should do a standard preparation. Standard preparation is your ideal preparation that is done through the standard books. The language used in such books is easy to understand for the students. The explanation of the concepts is done in such a manner that it is easier to learn them. You should avoid preparing from a lot of books. This will only confuse you more. Stick to the standard books and prepare with true hard work.
During the preparation, solve a variety of test papers such as the mock tests. Take weekly and monthly mock tests. Once you have completed the exam syllabus and are close to the last month of preparation, start taking the full-length mock tests. It will help you in analyzing your preparation well. You can also join some online test series such as the Brainstorm Achievers online test series. It will help you in keeping track of your preparation.
Aim for time management and accuracy
If we have to narrow down two important factors in GATE 2021, it will be your speed and accuracy. Your time management skills will come in handy in this very exam. If you think you have to work on your time management skills, do it during your preparations. Mock tests and online series are the best methods to improve your speed and accuracy. You see, both of them are interrelated so if you improve your speed, your accuracy will improve on its own.
Practice online calculator
One of the areas where the candidates lose marks is the online calculator. They usually forget to practice it or just take it for granted. It will be better if you prepare online calculator before taking the exam. This will help you a lot during the exam and you will also save time if you are prepared in advance.
Self-motivation is like food that you require daily. Try to be in good spirits and prepare for the exam with optimism. Stay clear of all the distractions and negative vibes that make you doubt your potential. Just keep in mind that it is okay if you don’t clear the exam in the first attempt.
Books for GATE PH Preparation
When you are picking your study material make sure that it is of good quality. Your study material affects your preparation and ultimately your results. Always go for books from famous authors or publications. We have suggested a few such books for you below.
