I asked Bristol if I could sit in on their brush up course after attending a lesser school. They gave me all the notes at a really good price and charged me a nominal amount to sit in... as it turned out they were running two classes of module one at the same time, so I could attend a session of met, go next door and do it again if I needed to.
I would not have passed all the exams if it hadnt been for them. As for using a CD instead of sending a great heavy wad of notes... saves on postage, saves the odd tree, makes sense. Welcome to the 21st century! Im sure its not beyond the abilities of your friend to get to a pc and have a look.
