Nephew loves them. I was happy that they worked since they were shipped in a box 3 or 4 times to big and got bounced around.

This is arguably Gruber's best contribution yet (compared to past editions) for the current SAT. I actually use it with my students (with some modifications) even to introduce skills that pertain to the ACT. The reason I've used 100s of Gruber's books to date is because he focuses on critical thinking, while other publishers are more problem oriented. I'd rather have a strategy that deals with multiple types of problems and explain how the same methods work every time, regardless of the situation
