Non-recurring Subscription or time limit for one-time purchase?

I'm in a bit of a weird spot. We have a product in the members area that is a 9 week group study course. Because we want the user to purchase the course for each group that goes through it, we don't want to charge a single access fee with full access forever. I was going to go with the subscription plan and charge for 6 months, which will give plenty of time for the group to go through the study. However, I don't want it to automatically renew their subscription after 6 months (because they don't necessarily need it. Is there a way to turn off auto-renewal or let me charge a one-time fee with a time limit for access?

No, you cannot charge a one-time fee and limit access for a set period of time. You can do one or the other:

• Members who pay on a recurring basis (weekly, monthly, or yearly) can only access the member area for as long as they continue to pay. 
• Members who pay a fixed amount for membership will have membership indefinitely. You can manually cancel someone's membership but they will lose access to the gated content in your member area immediately.
