any response/suggestions are appreciated.

Personally I dont' think any GMAT materials are close enough to real test, including Princeton, MCGMAT, Manhatten, Kaplan, etc. And trust me I tried quite a few of them. The best materials out there is OG. Get your hands on all OGs, like OG10-12.

Math: most of the math books are relatively easier than real test, simply because they are not CAT. i.e. they won't give you harder questions if you get a few questions right in a row, nor will they give you a similar question if you did the previous question wrong. When I did the GMATPrep and real test, the questions are always harder because they match with your performance. One trick you can do is to copy 37 questions from here (beatthegmat.com) into a Word file, and do it as a test (and time it too). Questions posted here are usually harder questions. It may help you mentally prepare for the real test.

If you are weak at math, I'd also suggest to break it down and practice section by section: algebra, geometry, probability, etc. Since you got only 2 weeks, I'd recommend you to focus on math for one full week. Personally I think math is easier to improve than verbal.

Another suggestion: remember GMAT is an ability test, not a language or math test. There's a good reason for all business schools around the world to use GMAT to size up applicants. They are not only testing your quantitative or verbal knowledge, but also evaluating your ability to focus and perform under pressure. You need to stablize your performance with simulation tests, and think GMAT as part of an interview (as some companies would use CAT tests for their interviews).

Anyways, just some thoughts. Wish you the best luck!
