"If there's going to be an SAT, it's probably practical to invest in a book or perhaps in a course, but I'm sorry to say, I went to some classes that my kids took and it was clear in school that what they were doing was just SAT training"

This quote by Robert Sternberg recommends that while it may be practical to purchase a book or course to prepare for the SAT, the classes his kids took were not especially valuable. He implies that the classes were just concentrated on mentor students how to take the SAT, rather than teaching them the material that would be evaluated on the test. This suggests that the classes were not particularly efficient in assisting trainees to understand the product, but rather were simply teaching them how to take the test. Sternberg's quote implies that the SAT is not a reliable step of a student's knowledge, and that it is more important to concentrate on finding out the material than on just discovering how to take the test.
