The main point is – GATE exam is lot conceptual & it is easy if your concepts are good, It is better to give more time to concepts.
Even if you have less time, at-least get the syllabus, get the topics in syllabus & study those topics from text books. After that see GO book for different variety of questions .
Then do a couple of questions from each topic, move to next one as soon as you are comfortable. Make sure you revise the concepts regularly & be confident..…
Anyway those who are preparing are expected to cover all topics by this month end. And they should be scoring 60+ in full length mock tests or minimum 50+. But the key is in getting this to improve by another 15-20 marks over the next 2 months.
This requires careful analysis of the exam performance - identifying weak topics - and making them strong (Even without any exam, you should be knowing your weak topics), learning how to avoid mistakes, learning how to optimize time better etc.…
But after this self improvement and revision must always be done individually. I was never a preacher and yet this is my third blog. I just wanted to say these for a long time.
Hope I have said everything now. All the best for GATE 2022 :)
