Wow i woke up late, i have 1 minute to do this. lol, k so this unit was pretty tough, the groups helped a bit but if everyone in ur group doesnt know whats happening too or is giving false information, that pretty much screwed me over. i liked the groups though, half the time it did help me. my muddiest point was when to use nPr and nCr, that pretty much kicks my butt!
