Review of my plan to boost my score

Hi guys,

So, this is my first post here, but I've done some reading! Last friday I took my first GMAT and ended up with a score of 570, were a score of 600 was needed for my application. I screwed up on math, and did pretty decent (I guess) on verbal. No AWA or IR was required.

So, after some reading here I've come up with a plan to boost my score to 600+ (which I think should be possible). I started studying for the GMAT on the 5th of January, for about 2 hours on weekdays and 4 hours on weekends while working 32+ hours a week, and doing sports for about 12 hours a week. About 3 weeks before my GMAT I took the first GMAT practice exam and scored exactly 600, which I was quite happy about. I did some extra studying the following weeks and thought it would be wise to take another practice exam about 7 days before D-Day. I hesitated a lot before actually taking the second practice exam, because it just didn't feel right, I felt unfocused and not ready. I scored a 500, miserable.

I've now planned a new GMAT, on the 9th of April, approx. 30 days from now. Some people find this too soon, but I'm motivated as can be to get my 600+ score. I've studied the Manhattan GMAT books, and I also have hard copy versions of the OG 15 edition. By the way, I have finished my BBA last July.

In short;
GMATprep CAT 1: Q40, V37, total 600
GMATprep CAT2: Q36, V26, total 500
Real GMAT 1: Q33, V35, total 570
GMATPill CAT: Q28, V26, total 460 (felt really 'off' that day)
The Economist CAT: Q37, V31, total 560 (felt good)
Veritas CAT: Q40, V35, total 620 (felt good, but thought the CAT was a tad easy)


I was wondering what you people think about my plan/schedule for the comming 30 days of studying, with the goal of improving my score from a 570 to a, let's say, 620.

Week 1;
- Create a plan/scedule to get my GMAT score from 570 up to a 620
- Create an error log
- Review the two practice tests again, make notes on which area's I should focus (these 3 should be done by today)
- Work on my math with the downloadable gmat math book of this site/forum (can't post links yet), (Is this a good choice, or should I pick an other book/method?)
- Check my verbal skills once or twice a week

Week 2;
- Continue with studying math
- Check my verbal skills once or twice a week
- 14 days prior to the real test, make another practice exam, and review this exam
- Adjust study plan according to the outcome of the practice exam

Week 3;
- Study on the weak points according to the review of my practice exam
- Intensify the studying, making more hours a day

Week 4;
- Up the intensity of studying a bit more, untill the 7th of April, then just do some reading on English articles
- Test day; score 620.

Could you guys give me a bit of advice, is my planning right, should I adjust it on some points? I think it's a realistic goal, do you agree?

Eager to hear from you, if you need anymore information, please contact me!

With kind regards,

Savage.
