So I just got a phone call from Jonathan Hall, chairman of certification exams for AGO.

I took and passed the Choirmaster exam!

I actually didn't pass last year when I took it, so it was nice to regroup and attack it again. Good experience. 10/10 would recommend to anyone interested in getting serious about personal improvement in organ playing and conducting. The AGO certification process in general is good, but the Choirmaster is especially fun because you get to work with people.
