How to Prepare for Physics?
Preparation Tips for GATE 2021 Physics Paper
- Knowledge of Syllabus and Pattern: Candidates must have accurate knowledge about their syllabus and exam pattern so that they can prepare a proper plan for preparations. Candidates are advised to go through the syllabus prescribed by the authorities only. The exam pattern of GATE is also released every year by the authorities so you must stick to that only.
- Download Practice Papers: Candidates must download the previous years' papers for practice. These papers will you in getting a better idea about the exam pattern, type of questions, difficulty level of questions, weightage of sections or topics, etc. With the help of practice papers, you can also work on your weaker areas. Download GATE Practice Papers
- Prepare a Time Table: Candidates must follow a trick time table to prepare well for the exam. You must devote 6-8 hours every day for preparations only. You can also take frequent breaks in between for relaxation of body and mind.
- Revision is Must: Prepare handwritten notes during the time of preparations. These notes should include all the important formulas, points, tips, tricks that are required to solve the questions. Daily revision of notes will help you in memorizing things for a longer period of time.
- Accuracy and Speed: To improve speed and accuracy, you must practice more and more practice papers or online tests. Candidates must solve 1-2 practice after every 3 days. You can also take mock test to check your speed and accuracy. Do not get disappointed if you are not able to do well in these. In fact, you must observe your weaker areas and start working on them.
