I am resitting my DAT exam and have some old materials from when I last took it. I have the 2011 version of the DAT Destroyer that was given to me by my sister, who wanted to take the DAT then decided against it years ago.
Is it okay to still use it for the 2017 DAT? I imagine that the questions haven't changed THAT much, although I know some Quant. Reasoning has changed.
I am also using DAT Bootcamp, Chad's, Cliff's Bio as recommended by Ari from DAT Bootcamp, and old notes I had from science courses.
Any recommendations?
THANK YOU IN ADVANCE!!!!!!

buy a newer version if you can. better questions and explanations are added each year. They spend a lot of time improving the book year after year
