For your Verbal score's sake, I would at least pick up the MGMAT SC
book and use that instead of Veritas
' two books. There is no comparison; MGMAT blows Veritas
right out of the water in this area.
MGMAT's math materials also seem to fill gaps left by the Veritas
materials. I would encourage you to take a look at any of those books to see if they help you as much as they helped me during my prep.
materials actually use many of the questions from OG. However, figuring out which ones are and which ones aren't is not a fun activity. You may be better off spending some extra time on the difficult OG questions straight from the source (the questions are ordered by difficulty in the 11th edition books).
