<p>I've seen them mentioned a few times on here and was just wondering what they are.</p>
<p>:P anyone?</p>
<p>I think that they are similar to AP classes. According to wikipedia, they are accepted at universities across the world, and sometimes they are taught in different languages. I don’t know of any schools around me that use it, though.</p>
<p>it’s not like ap. Some people think of it like that, but it is not.
A simple forum search should give you all the info you need.</p>
