A pretty good start ...

... that's what my S330 tutor wrote on my first assignment. But, 63% - that's not pretty good! If I can only manage that with the books in front of me, what am I going to be like in an ex*m?? I'm kind of 'there', but I don't go deep enough. I'm not sure I understand it enough to go that deep!! He liked one of my diagrams.
