Hey Crack_it!!
I finished all quant questions in Barron's (which I think were pretty useful. They also have nice quant review). Kaplan 800 was so so.
OG Gmat quant questions was very useful.
I think the exam in general was very close to Gmat prep (including verbal). I got one very long and difficult reading comprehension text, but the rest was the same level as GMAT prep.
Good luck!
