I need a word to convey the meaning of getting a course approved w/o ever going to class

I've recently started working at the International Office at my University and I've found myself in need of an English word for succeeding in a test and getting a course approved without going to class at all. In Spanish it would be "rendir libre" for you bilinguals out there. Thank you in advance! This is my first post here btw, I hope I followed your rules neatly!

Solution 1:

In English, you'd say that you "placed out" of a class. That means you get credit for it without having taken it, and it implies that you took some kind of placement exam or assessment test that demonstrated that you had sufficiently learned the course material.

From The Free Dictionary:

Place out of

To qualify for a waiver of some requirement or prerequisite: If you've placed out of introductory biology, you can take an advanced course. The school has a language requirement, but since I know Spanish, I placed out.
