<p>I was wondering if grubers' complete sat book is useful at all? I already have CB, BB, and PR. I was deciding between Kaplan and Gruber's, and I ended up with Gruber's. Because I had already completed the three main books (blue book, BB, and PR), the only choices at the store were McGraw Hill, Kaplan, and Gruber's. I took a Gruber's practice test and I did really badly-MUCH worse than usual. Are Gruber's tests harder than the real SAT? How is the critical reading material/strats and writing that they give you? Also, math is my strength, and I feel like ALL that math material is WAAAY to much and unnecessary. Are those math reviews useful? ARE THERE ANY OTHER PREP BOOKS TO USE (for practice tests mainly;l I don't need strats or review anymore)???</p>
<p>I finished McGraw-Hill’s 12 practice tests, and I tell you what, it’s worth to use it.</p>
