Released PSAT tests

<p>I'm preparing for the SAT (and consequently the PSAT) and am wondering if it's a good idea to buy released PSAT tests for practice. I've heard that a lot of people recommend just using SAT tests for PSAT prep, but I want to save as many SAT tests as possible in case I need to retake. Plus, the PSAT practice tests will obviously be a lot closer to the real PSAT test than the SAT practice tests.</p>

<p>The second thing is that the PSAT tests don't come with answers (I assume so, considering it's just the test booklet for $3). Is there a site where the answers are posted so I can check my work? And how would I go about determining the curves for each section of the test so I can determine my score? Thanks.</p>

<p>I imagine, if you use a SAT book, you are fine.</p>

<p>I heard that if you call collegeboard, they will send you the answer by email.</p>
