Study.com allows you to change your subscription status beginning with each month's anniversary date. So you could signup for the $100/month plan and then when ready to test for credit (2 max), upgrade to the $200 plan, and then retrograde to the $100 plan until ready to test again. I look at it as paying $100 for test fees. Give that you don't have to buy textbooks, it seems very competitive to me compared to SL especially if you like structured course video learning, although it's been reported in another thread that the quality of video content can vary widely among courses.

It's always $200 to test because you have to upgrade to get the eligibility.
