<p>Essentially, yes. But it’d be just like taking the same exam twice. Say I get a 2 in AP World History one year, for no credit, and then take it again the following year and get a 5 – which is actually worth some credit. Same concept: if you don’t do great on the AB exam, which in my case, I don’t think I will, you get to go through it all over again (plus a little more) with BC, and then have the potential to earn whatever credit BC offers plus do better on the AB content and get a higher subscore.</p>
