Hey there,
My friend made me copies of these tapes and I learned a lot from them. The night before my DAT's I listened to the bio part and I scored a 24 in biology. There is over 500 pages worth of information in these tapes. If you want them, PM me and I might be able to sell them to you. Remember these aren't the originals, but quality is great, though. I think 99 bucks is too much.
