Have you got any background? I suppose if you've taken some adult classes then maybe you're ready for grade 5. I could be wrong, but I guess if you understand all the 5 positions of feet and arms, and how they should roughly look like, you can enter a grade 5 class and learn the rest... haha

I had a hard time teaching this girl who had no background the basics, but she dances modern dance quite well, and well, they're quite similar.

Just try grade 5 I guess, you'll be fine... not sure about north... There are good teachers in the east Of course, the other students can tell you how good their teachers are too, so, you'll just have to find out for yourself haha.=)
