Cheap Self-Paced Language Courses or courses IN said languages?

[nykorn]

Looking for CHEAP self-paced language courses/degrees/tests that grant credit and never require live or in-person meetings. These can be titulo propio or similar, as long as they grant credit. Alternatively, as a sink or swim method, cheap courses that are taught IN those languages, but entirely self-paced and open to foreigners. For example, I can register for a free university course in Germany, but those typically involve live, required lectures and homework deadlines, which is a no-go. Mainly interested in Chinese, Korean, and Russian for career purposes, but am open to other languages including minority languages, hence making this a general thread about all languages.

What I've found so far:

Chinese:
HSK - $20-$100, test that, at the highest levels, grants credit at some few universities

French:
Sophia - French I, $99/month before referral discount
CLEP exams (up to 9 US credits), roughly $100, test fee gets reimbursed at Modern States

German:
CLEP (up to 9 US credits), $100, test fee gets reimbursed at Modern States

Japanese:
JLPT - $60-100, test that, at the highest 2 levels (N1, N2), grants credit at some few universities

Spanish:
CLEP exams (up to 12 US credits), $100, InstantCert has a prep course, test fee gets reimbursed at Modern States
InstantCert - Spanish I (3 US credits, $15?), separate course from above
Sophia - Spanish I and II, $99/month
ENEB - Spanish for Business Certificate course, included with their English €99-€300 Master's titulo propio programs. 
ENEB - Titulo propio in Business / Management subjects, taught in Spanish, roughly €99-€300.
Masstercursos - Titulo propio in Humanities or Psychology subjects, all courses are self-paced and taught in Spanish, €299 before discounts

Swedish:
antagning.se - Some random courses taught at university level are mainly self-paced and have no mandatory live lectures (especially some computer / tech related courses and iirc Yiddish). There's still an overall course or homework deadline but you wouldn't be penalized much (in some cases, at all) for late assignments. Some have recorded lectures or lectures that get recorded after the fact, thus no mandatory live lectures. $0 for European residents or citizens.
