I'm studying Philosophy of Religion, (A posteriori, A priori) on the side. I'm additionally perusing 45-50 books on Metaphysics, ontology and Epistemology, albeit, I'm not going to immure myself into studying an A-level in the field. Philosophy is a motif for rationality, and it's not rational to test yourself on rationality. That's irrational.
I might disinter Philosophy of Islam and other forms of Religion, but we'll see whether or not I'm didactic enough for a sixth AS!
How 'bout you?
