Accessible Handwriting Tutorial App for iOS

I've been blind since birth, and I'm a VoiceOver user. I recently discovered that the handwriting mode in the rotor is accessible with VoiceOver. I was never taught the complete alphabet, symbols, special characters, etc., when it came to writing print in school. Is there a VoiceOver accessible tutorial that I can use to learn that? I know braille inside and out, but being able to use the handwriting mode would speed things up a lot.
