I started looking at the Khan Academy videos
. I am sure they will be helpful no matter what. One thing I am concerned about is that he is using an older edition of the OG GMAT book. I have OG12
. Does anyone have a correspondence between the older edition used at Khan Academy (with 404) questions and the current edition? This would be very helpful. I would like to try the problems and then see his explanations.
Thanks in advance
