PSAT and SAT

<p>I decided to take every possible test, but i don't know how to find.. Is PSAT reading section a lot different from SAT reading section?, and which one is more difficult.. is it SAT?.. Please tell me how to get more actual tests except from the official study guide. One more question is that are the tests in the online course the same tests with the tests in the official study guide known as blue book??.. Thank you.. </p>
