Mock Tests are useful for GATE — but only after you know the concepts well. Never ever try to learn by giving the mock tests. The tests must be used to see how well you can apply the concepts you know, how you can understand and skip difficult questions, how to optimize time in answering a question etc. For good tests like previous year GATE papers, you can spend a considerable time analyzing and seeing which all topics lost your marks and then seeing how you can improve on them. Many of the below tests even if paid have a considerable amount of wrong questions and answers and so if you are giving them — beware. Personally, if I’m taking GATE I will just take the previous year GATE papers, some free tests and if I have enough time then the tests by Testbook. I have very poor opinion of the question standard of any other paid test series and doing wrong questions corrupt your knowledge and will only reduce your final marks. GATE stands for quality and not quantity — choose the tests wisely.
