univ/colleges offering chemistry units but online classes

Hiiii! 24F here, a BS Biology graduate.

I’ve always wanted to take BS Chem but unfortunately the school I went in college did not offer it because the number of enrollees did not reach the quota. Now, I’ve graduated and I want to pursue a career that is Chemistry-related but I need to take up additional units to take licensure exam.

Is there a university or college that offers Chemistry units that I can take online?

I could not, unfortunately, take classes face-to-face because of financial issues, also I am working part-time.

Salamat!
