Question Regarding Advice from a prep class instructor

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.

The Veritas 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).

I think that Veritas just wants you to buy into a strategy first and then use that strategy to solve additional problems. People may use tons of material and go through tons of problems but you'll find those who use a specific strategy consistently do well.

Oh and the problems from Veritas are typically from the OG.

They're mixing questions from the OG with theirs for homework assignments?! That would totally irritate me. Princeton Review just gives you the OG and assigns it for homework.
