The reviews for the book say the exams are way too hard or not the right material, but I see posts and talked to people that say the real exam was harder than the ETS exam (9768) and Princeton review exam, so isn't harder practice exams good?
I don't think the tests in this book are harder than the real exams. Basically, the tests just only focus on calculation stuffs and the theoretical questions are really basis. But any way, it it a good book for preparing for the real exams
Wish you guys success on the GRE Maths tests.
