Listening to the bar

So I'm still studying for finals but I'm already thinking about the bar studying.

I finally got around to opening the package from PMBR and it contains two massive books, a huge pile of index cards and a box of CDs. By my count, that's 35 hours of lectures on 30 different CDs. Am I supposed to listen to this stuff? Maybe I need to put it on my iPod so I can listen to it while I work out? I don't really have a commute to school (10-15 minutes each way) so I'm not sure when I'll have time to listen to the CDs. It seems excessive - and almost counter-productive - if I have to sit around listening to the CDs; I can't pay attention that way. I assume the CDs replicate the lectures but who knows? I guess I'll find out whether they really need to be listened to in a few weeks once the fun begins...
