I found that studying 30 min-1 hr in the morning before work is the best way to absorb the material. I spent approximately 75% of my time doing OG or GMAC software problems and 25% of my time reviewing answer explanations.

If you are short on time, I suggest skipping the first half of OG questions in every section because those are the really easy ones that you probably won't see often on the real test.

Everyone,

Thanks for the advice. I appreciate hearing the help and the fact that not everyone who necessarily studies 6+ months for the GMAT will instantly score a 700+. The two diagnostic tests I have taken place me at 630 and 650, so I know my starting point. Thanks for the advice, and I look forward to posting more over the upcoming months.

I don't think that most native English speakers with a quant background, which you seem to be from your posts, need to study 6+ months for a 700+.

I went from a 650 diagnostic to a 780 Preptest and a 730 on the actual test myself after only ~20 hours (1/3 of OG13 + 1 Preptest + review) of focused studying, and I think that most others have seen similar gains after the initial period of getting used to the GMAT.

Just make sure you use the right (official GMAC) material to study and make sure to learn the concepts behind the questions that you got wrong. Good luck!

Some good advice here.

We also recommend reviewing concepts just before you go to bed and again when you wake up. This helps your brain retain memory better the next day. Do this every couple days and you'll make good progress.

The 3 resources we recommend are:
1) GMATPrep software from mba.com
2) OG 12/13
3) GMAT Pill course. You can also practice questions here: https://www.gmatpill.com/gmat-practice-t ... -questions

Wow...
100-110 hours means that you work, say, 16 hours M-F and 12 hours on Sat and Sun (16*5+24=104), right?
16 hours a day means e.g. 8am-midnight plus commute plus shower. How do you manage to study for TWO HOURS after that? I guess, few people can give you advice - you probably know better yourself.

I can see several solutions:
1. If you want to do your work well, do not change anything. You will simply need more time to prepare for the GMAT. Perhaps you can postpone it for a few months.
2. Tell your colleagues/boss/subordinates that you need to reduce your workload so you can study for your B-school application. Explain that you will not be able to work effectively anyway since you will not be getting enough sleep, so you may make some wrong decisions, and the company may suffer. If this does not help, either switch to choice (1) or quit your job when you have enough money. You would have to do it anyway so you can attend a B-school.
3. If you don't really work 100-110 hours a week but are only present at work during this time, you may be able to study at work, particularly if you are sitting at a computer and if you have Internet access. However, there may be a risk to your reputation, which may also affect your B-school application.
4. If your position at your company is not very high and you cannot be honest with your manager, then simply go to bed late or get up earlier, sleep less, and keep studying. At some point you will get really sick. Then stay home and study in bed. Just make sure you have friends nearby in case you get REALLY sick.
