<p>If you've done all of the tests in the BB, College Board has 6 online tests that you can take.</p>
<p>For CR - practice, practice, practice. I know you've done 8 tests but do some more. Don't just absentmindedly work them, make sure you understand the ones you get wrong. That's the key to improving. For sentence completion - vocab. DH is good.</p>
<p>For W - same sort of thing, practice. Learn how to write a good SAT essay and just practice a whole bunch of multiple choice.</p>
<p>Just don't use any practice tests that aren't made by the CB.</p>
<p>You need to sign up for the CollegeBoards "Official Online SAT Course". You can find it on their website under SAT Prep.</p>
<p>I strongly recommend that you print out the tests before you answer them though, since reading paragraphs on computers and on paper (at least for me) are two different things.</p>
