Anyone know if there is a difference between the older versions and the newer one? I ask only because I will probably run out of passages in the newest edition (2008) long before I am done studying and I was hoping to find some more EK passages and thought maybe the older editions would have different passages than the newest edition possibly... any chance? If not, what would be your next best choice for more VR practice? I have TBR and Kaplan but am definitely not against picking up more if there is something better and more along the lines of EK.
