OG is a must. I've heard Kaplan instructors don't even tell you that it exists. Its not a bad idea to practice Kaplan math, but for verbal, i would recommend sticking to the OG. The verbal questions you will see on test day will resemble OG questions.

Yes, definitely practice with the OG. It's too bad that Kaplan doesn't use it with the class. PR does, and I think they're better for it. The questions get harder as you go through the OG, so work carefully, and do keep track of your errors (there's some great info on this site about error logs).

I would use PR for verbal strategy if you can stomach getting another book, as they're stronger in that area. Lots of people pick and choose strategies from different sources as they see what works for them.

It's rough studying that much each day, but give yourself breaks and eat well, and you'll stay charged up. If you feel mental overload, go for a walk or a run, watch a silly cartoon (Spongebob does it for me!!!), or eat a snack.

Good luck!

Can I ask a dumb question? What is an OG?

Official Guide for GMAT review written by GMAC. It's a must have resource.

For OP, i think your best thing to do now is to take a diagnostic test under test conditions and pinpoint what your weak areas are and work on those areas. Overloading on information is never good.
