Firstly, Keep only two things in your mind:You have to qualify GATE.You have to face written &/or interview after qualifying GATE.So, your approach should be having at least basic knowledge of your subject and having deep knowledge of syllabus.Study according to syllabus first. Prepare short notes.Solve section/unit/topic tests simultaneously.Study weak unit/topic first, overcome your fear of those topics and questions.Solve previous year papers, starting from recent ones.Solve mock tests.Have at least 1–3 strong topics for interview. Prepare from beginning.Don’t leave a que/problem, because you can not solve it. Try it or ask it or search it. Study whole topic of that que.For more details visit - https://professoridea.com/gate-2020/
