Is there any difference between Official Mock 1 and 2 (which is free) vs 3 and 4 (Which is paid)??
Hello,
Shreyaskn. As the numbers themselves suggest, practice tests 1 and 2 are older. As such, some tutors and test prep professionals feel that the more recent tests, 3-6, better reflect the exam in its current state. To be honest, any practice with official mocks is useful practice. Since the first two mocks do, indeed, have a deeper question pool, and since you are able to reset them as many times as you like, you may be able to experience more than one unique test using the same mock. The question pool for the paid mocks is quite slim by comparison, and you get a single reset—repeat questions are much more common.
If you can afford it, I would recommend purchasing the paid exams, whether in one pack (3 and 4, or 5 and 6) or both. Gauging your performance across several official practice exams gives you the best idea of where you might stand on test day.
Good luck with your studies.
