Online / Challenge Credits Physics Course ???

My Brother-in-law is one course away from completing pre-med school in St/ Lucia. [He was an OT for several years.] He was 2 away and completed a biochem class via challenge credits, where you just take the exam, at athabasca university in canada. His med school in St. Lucia is acceptiong this.
He still needs a physics class, and we have been unable to find one that offers challenge credit.
Anyone aware of one???

The only University that I am aware of that offers challenge credits in Physics is Ohio University, they offer the option of taking an exam to receive credit for their physics courses in their distance learning department. There are other colleges that offer courses online or through correspondence.
