Do I have to use Members Pro 2 with CoursePress

Hello,
I know a few months ago a sales rep told me that CoursePress works well with Membership Pro 2. My question is do I have to use Membership Pro 2 with CoursePress in order to sell online courses? Or can I just sell the courses using CoursePress Pro without the need for Membership Pro 2 and MarketPress?

Waiting for your reply.
Thank you.
