Well, I'm going to start a little journal.
Basically I got a 750 - 50/41 a few months ago thanks to GMATClub. But I didn't perform up to par on test day, let's just say that.
So now fast forward: I've made my living through gmat tutoring, and effectively been paid to study the GMAT. Quite a good living at that, and let's just say I've seen every single question imaginable. You really get good at answering questions quickly and correctly when not getting a question right might mean not keeping a client : ) I did a practice paper test the other day, 800, significantly under time (about 12-15 minutes per math section), so I'm in good shape.
I've developed a pretty unique methodology that stresses mental endurance/speed, which is absolutely critical to performing well on the GMAT. Out of about 40 clients, 14 have scored 700 or higher, and 2 I'm currently tutoring are going to hit 700 or higher as well. I'm actually thinking about writing a book on it, but between tutoring and my other business I barely have any time.
Anyways, to make my app more competitive and due to competition from other tutors, I've decided to rewrite. And because of what I do, I'm aiming pretty high-- 790-800.
The 51Q I'm not worried about at all, but I do need to stay sharp and to work on speed a bit on the verbal to nail a 50V+.
I'll try to take a GMATPrep in the next few days. I'm going to be working off GMATPrep, Paper Tests, OG10, OG11, and PowerPrep exclusively (which is what I use with my clients, Kaplan/McGraw/Barrons/etc go promptly into the garbage
).
I'll post in here as I study... I think I'm going to book tomorrow or the day after, so I'm motivated to study : ) Otherwise laziness will force $50 to go down the drain to reschedule the exam... hah
