I'm in Management Consulting and prepped for my GMAT from Feb to June. I was lucky that in all of that time I didn't do much travel, just had the typical 10-12 hour day.

I guess it depends on how much you want it really. I scored 540 on my GMAT first time round and knew that if I didn't do it this year then I might as well forget about it. So I put everything in to it and forgot about everything else, it became my sole obsession. It helps that I have an understanding wife!

The only way you will get a decent score is if you do 2 hours at least each night on the weekday and a few more hours on the weekend with a practice test if possible. I used to do 2 hours a night Mon-Thur, up to 5 hours on a Saturday and a practice test on the Sunday. You have to be disciplined and innovative. Come what may you need to set aside 2 hours every week night else, unless you're a genius, it's unlikely you will hit 700.

You probably think that's not much help but my main message is if you want it badly enough you have to make the time!

Well, as a former management consultant I can tell you it's not easy. But you can consider some online options that are geared towards efficiency since you are limited by time. Consistency every night before you go to bed is important for reinforcement. Let the weekends be your hardcore sessions---at least 3 sessions on those days---each session 2-3 hours.
