<p>I think Xylem may mean grading yourself solely off how you "think" you did on the multiple choice, and later looking at the free response answers (if you wrote exactly how you did your problem in the scrap booklet they returned to you) when they post the answers on collegeboard. HUGE waste of time really, you obviously know generally how you did by the 1,2,3,4,5 score you were given.</p>
