Take it slowly. You aren't going to get there right away. Stay consistent and work on this for at least 30 minutes in a day; although, 60-90 is preferable if you can keep up the daily routine.

As for the topics, here is how I break down the quant section: GMAT Quant Review

Two tips!

(1) If you live somewhere that has public transit, take that in the morning/evening and try to study on the train.

(2) Use your lunch break! If you typically walk somewhere to eat with coworkers, be antisocial for a bit, bring your lunch/order delivery, and work on questions for 30-60 minutes during your break.

The more study time the better, especially if it's time where you aren't mentally exhausted (read: after 12 hours at work.) You want to study EVERY DAY: the GMAT, like a language, responds best to immersion. (If you only study on Saturdays, you'll be spending most of your time catching up on everything you've forgotten since last Saturday.)

Thanks everyone! I plan on taking the test in mid November. I am dong okay so far, but I am having issues with the algebra. I have read the chapters in my Kaplan premier book, watched the classes, and have done many problems. It just is not clicking. Picking #s is tricky and so is the data suff. It could be poss or neg, integer not an integer, etc ... It makes my brain hurt! Oddly, I am not too bad a geometry for never taking a class. I borrowed my nephew's Math is Fun! workbook and learned geometry that way.
