Looking for a school for science classes like Chem

[Heath]

Looking for a regionally accreditated college. For a high schooler. Fully online course. Proctoring no problem at all. Lowest cost option possible. Dual credit, okay. Concurrent enrollment okay. Traditional okay.

Has to be college can't be ACE. 

Courses needed are:
Chem 1 
Chem 2 
Org Chem

Can anyone recommend a school for this?

Tohono O’odham Community College is $35/credit and has chem 1 and 2. I'm not sure how it works with high school enrollment.
