I am serious. I would be happy to, although I am sure that Professor McGonagall would help you as she did with me, during the school year. In the mean time, we could get started now.
I studied human transfiguration all through my sixth year and seventh, and was just about ready to become a registered animagi when I graduated. Unfortunately, the war was going on then, and there were more important things that I got involved in and had to put that dream on hold.
In a way. Your animagus form is very deeply rooted in your personality. I've always felt it was a mixture of choice and what suits you the best.
