<p>if you know your AB stuff VERY well, then you could actually take the BC test and get a good grade on it!</p>
<p>i remember when i was taking the BC test, i had no idea how to do all the C material (including 1 or 2 FR questions that i just completely bsed :(), but my strong AB knowledge helped me get a 5 (and naturally, a 5 on the AB subscore)</p>
<p>if you are learning AB in school, and have a few spare mins a day to self-study C stuff, its a good option to take</p>
