Will having a B lower my chances considerably?

<p>ok, since all of your are talking about grades now, i got one really big question that i think your might not be able to answer…</p>

<p>In grade 10, i took my national examinations( im asian and international), and i failed my chinese examinations which is the toughest that a student can take owing to the fact that i was sick on the day of the examinations…During the preliminary examinations which is to gauge what you are likely to get, i got a A, so it came as a surprise when i saw the freaking B…Does that totally kill my chances or do i take the AP chinese or SAT Chinese which from many of my classmates view, is a total joke as everyone is confident that they can get a 5or a full 800 without even studying…</p>
