If you are developing the habit of reading to prepare for the GATE 2022 exam then try to make short notes. It will help in revising the GATE tome that you have already studied. Short notes can be easily read later and this also refreshes the memory.
While making revision notes for the GATE exam, note that important terminology, definitions, and formulas should be included in it otherwise it will not be useful during the revision time. Make it a short guide to the syllabus.
When you are studying any topics, at that time carefully look at each important point of the subject. After that try to understand its relevant topic. Once the concepts of the topic studied are clear, make a summary of it by jotting down all its important points/steps.
Make it at least 3 to 4 times a month. This will let you know that you are not burdened with the task of making notes for the last part of your exam preparation.
