try this
http://www.power-chord.com/gaff/mapper/?verbose=1
it builds scale and arpeggio diagrams for you to practice.
I did this by hand for years and it really annoyed me. I'd seen the site before but I didn't realise that you could include your own scales too so I didn't think it was much use to me. But lo.. you can!
If I couldn't laugh at myself how could I laugh at someone less ridiculous?
