<p>So I was checking out the Sparknotes website and it seems to have a large amount of review and practice tests available, for the SAT, ACT, SAT II, AP, etc. The review seems really helpful, but I'm curious as to how accurate the tests are. Are they generally a pretty good representation of the actual tests? There is a lot of resources and it seems like a great place to study, if the tests are accurate enough.</p>
