Where can I find UL courses?

[hlg38]

I've done some digging, and maybe I'm just missing something. On Study.com, for example, even when I select "College Senior" and "Online College Credit" I still get a bunch of 100 level courses for my results. I need various courses in the 300's and 400's.

I am only a few classes away from graduating from Excelsior with a Bachelor's in HSEM.

I need 12 credits of UL arts and sciences, and 6 UL credits in any academic area. This should be easy enough to find, right? Where can I take a bunch of foo-foo UL courses that's not a university? 

Thanks for y'all's advice.

Oh! I found some upper level courses on Study.com. Jeez, I should have looked harder.

Any other resources out there, though?
