<p>I have no doubt that collegeboard book has the best practice tests
since they are very similar to the real ones.
What about other ones?
Barron's, Princeton Review, Gruber's, Kaplan?
I heard Barron's is too hard
PR is just little harder than the real ones
Kaplan is too easy
Is it really? Any confirmation or Correction about difficulties of practice tests that i just mentioned?
Anyone knows about the Gruber's? (planning to purchase just for the practice tests)
Any other books with excellent practice tests?</p>
<p>P.S. I am asking only about the PRACTICE TESTS in the prep books not other materials in them. PRACTICE TESTS!</p>
