I think so- aren't there only like, 2 or 3 videos per category you can watch before you have to buy the rest? Some intro ones? Yeah- I think I remember them being the same. Buy the videos- they saved me on the real DAT.
Chad's videos were absolutely crucial for my DAT. Really glad that it was so affordable and it was all I needed to get a decent score for gc/oc. I really recommend it. (actually im gonna say bootcamp helped a lot, too.. just realized after seeing pulltheleverkronk's post)
