So, I purchased ek for my study material. It has been a wonderful representation for most all the info presented on the MCAT except for the psych portion. My first practice was full of terminology and jargon I have never heard of. What would be best to supplement? Right now I am piecing together what I am missing and reviewing it via kahn. The exam is in two months, should I purchase supplementary material or stick with kahn? I don't want to find out too late which choice is the right one
