pharmacology online class

Im looking for a pharm class that I can take online, I am already in nursing school but my course plan doesn’t offer a pharm class. I would really like to take one just for my own benefit to help with NCLEX and just my personal understanding of meds. I am having a lot of trouble finding a school that will let me take the class, offers it online, and wont require me to be on like a course plan, I live in TX so in state would be great for financial aid purpose but I am willing to look in to online schools based out of state if need be I just really think it would help me.
