I actually have a question about this too. How many credits would be realistic to take a semester while in the regionals? I’m a CFI right now and about 10 months away from the regionals, and I’m only taking 7 credits this semester and it feels like a lot at the moment. I have 32 credits right now (not including whatever I can get from my pilot credentials), so I figure it’ll still take me a few years at this slow pace.
