The BOM's do stretch your abilities, which is not always a bad thing
but there is lots of hand holding to help you along on the forum should you have any problems. Margo's classrooms for this year have been excellent, not only for the BoM but as techniques in general. I believe they have the quantities for the kit all sorted out now (there was a hiccup at the beginning of the year) so you shouldn't have any problems on that score.
