Has anyone taken AP Spanish Language through Apex learning?

How is the course conducted? What is the workload like? I have a near perfect/perfect gpa so I don’t need it in that regard. Would it be counted into my gpa?

The course would most likely be challenging for me, but I feel up to the challenge and really want to learn more Spanish. How rigorously are they graded? If I were to find myself doing less well than I usually do in school, could I simply not report that I’m taking it at all and continue just for my personal benefit?
