Heya! Yeah, I found grade 2 a bit boring when I'd played the pieces so often I could play them standing on my head.
How about for tuning sticking nail stickers on the violin at finger position one and four. (i.e. for the A string the stickers would be at B and E) But if you stick the stickers in between the A and D strings you can use them for all strings and only your thumbs would suffer! (re-reading that it sounds VERY confusing)
Ciao!

p.s. I don't think I did much practise on my scales
