Query: BIGGEST WASTE OF TIME

I completed this whole book and it was absolutely nothing like the computer-test. The questions were so much easier in the book. For example, I was getting around a 730 on the quantitative with the review book, I ended up getting a 510 on the real exam. Now I am going to pay $2000 for a tutor because I am afraid that if I use another book it will be the same garbage.
