What parts of the 2006 Schweser audio CDs are still relevant?

My brother ordered me the 2008 Schweser videos and it included the 2006 audio CDs. I have about an hour commute to and from work and I’d like to accomplish something while I’m sitting in traffic. What LOS are the same and still relevant? My basic plan is to do the video in the morning before work, listen to the audio on the way to and from work, and then use the books when I’m home. How can I find out which parts of the 2006 CDs I should listen to?

If you’re interested in getting rid of the audio CDs, please let me know. I passed L3 in 2006, but we like to use the CDs as a refresher. Let me know how much...jciaio@hotmail.com…thanks. Jon
