Well .... I managed it on my own but that was during a summer when my father had practically imprisoned me in my room and I had nothing else to do but keep at it. James wasn't far behind, though I did help him with the last trick or two. And then we both helped Peter along.

From what I've seen of Ron, he's capable of it. It's just a matter of time. A coach isn't going to help on that score but it can't hurt, either.

Though one thing that gives me pause is that Terry's first transformation was in that moment of blind panic when he was fighting for his life. I'd hate to see Ron have to wait for similar circumstances.

Of course, I'm sure I could nip up there for Hogsmeade visits and we could work together then, too.
