<p>Is it really necessary to do every practice test in BB as a exam or I can do it part by part not as whole?</p>

<p>You’ll probably want to do most of it in parts, since most of us don’t have time for full length tests on a regular basis. But, you may want to do one full test at the beginning (the free one you can download from the College Board is great), so you’ll have a baseline. It’s not a bad idea to do each section you practice under timed conditions. Of course, be sure to go back and review all of your mistakes. Good luck!</p>
<p>thank you very much!</p>
