free TOEFL tests?

<p>Do you know any websites, documents, or links for free, or sample TOEFL tests (full test) + answer key?</p>

<p>I really need help on preparing for this test, and I can't find any practice test.
Buying it would be kind of dumb, cuz i heard TOEFL ibt is pretty easy, i just need to see how the test looks like and stuff really.</p>
