Jude, do not study solidly for 2 months prior to Alex's course, it'll be a waste of good time and give misleading preconceptions. Learn definitions and know basically what all the graphs do and how to go through them. His course takes it all from there - he got me through in December and I'm no Einstein! - brillian chap Alex! Just remember - second segment climb - 4.2%!
Bon Chance. Doc.
