Hey, The GRE mentor course have some 600 question to practice. How do I get to know that these are purely new questions or are clubbed from already available resources?
My understanding is that while some of the questions are new, others have been recycled from PPP1 and PPP2.
Okay, what do you recommend - buying it at $ 80 cost will worth it?
That’s up to you, but personally I would probably not take it (and instead use them towards practice tests).
