cubes and diags
well...
as i recall arround 35 diagrams (am sure 90%+ correct, probably 95%+).
Cubes I did all 40 of them, but i'd say about 40% correct.
I have no idea if they want precision, speed or a combination. I would guess on combination of both... I surelly would like to know the trade-off since its not inexpensive to go there for the testing and, except if you are very at easy with it (meaning, doing it all easy and on time), than it would be good that you can choose if you go for speed or precision without that being a guess...
Oh well, such is life and things...
Good luck!
