I agree with the post above. From what you said you were suspended for academic integrity issues and had to take an APA course before being considered for readmission. To me this sounds like you had a problem with plagiarism of some form and were suspended on those grounds, though I could be wrong, I am reading between the lines here so to speak. I don't know that my school would have even readmitted a student who was dismissed for academic dishonesty.
Regardless of all that, it sounds like you have jumped through all the proper hoops regarding your suspension and are ready to move forward. It sounds to me like the school is doing its best to set you up for success as you move forward in the program, they may be concerned that if, after a year away from school, they allow you to jump into the Primary Care II class, you may struggle academically or even fail the course. It would be a real shame for you to go through all the steps to be readmitted only to fail out your very first term.
At $7,000 for a 6 credit class, I can certainly see why you would be upset having to retake it. But for those prices I have to imagine that this is not a brick and mortar state school, and therefore it may be incredibly difficult to transfer any or all of your credits. So the alternative would be to apply to another school, attempt to gain admission after being suspended for academic dishonesty from another program, and starting over. It doesn't seem like a great position to be in either way, but if it were me I would suck it up, jump through the hoops, keep my head down, and focus on the end goal.
