I'm gonna try adding some audio instruction as well as hitting the books. My 215 book hasn't gotten to my house yet but the 215 Audio CD's from 
www.Trainsignal.com has. I was wondering has anyone else tried using them? It came with 4 CDs - 2 CD's for lecture and 2 CD's for Questions and answers. I'm hoping that If I replay them enough till the info sink in it will give me an early edge and maybe I can take the 215 Test a bit earlier than I expect to. I can imagine they would become very handy on them days I just get tired of readin. Then I can just pop in a CD lay down and just listen
