Hey guys, I've read quite a few awesome stories on this forum, and am hoping in the next few months I can post my own.

I spent the past two months studying roughly 1 hour a night and a few hours on the weekends taking the Kaplan on demand course (I got a great deal on it only $230!) although I admit I did not put my best into it.


Test Score Quant Verbal
Diagnostic 520 31 53
Cat 1 580 42 66
Cat 2 580 34 81
Cat 3 600 46 74
Cat 4 580 42 64
Cat 5 570 34 78
Cat 6 570 40 64
Actual 600 36 35

Background:
24 years old native english speaking male
3.5 GPA from decent quality public university (Clemson University)
I did have my own business through college recycling automobiles with roughly 60k in gross revenue yearly- This was done under the table which I regret since I do not know how to leverage this on a resume.
1.5 years of work experience as a product manager at a fortune 500 electronics company. No real extracurricular work outside of work aside from membership in a local "young professionals" group which does community service.

Goals
Ultimately I want to get into a top 25 school. Cornell, Duke, UNC, Kellogg, and Darden are all schools that I would have an interest in. I would also be interested in something international. I am torn between marketing, finance, or general management.

Regardless, I believe I need at least a 700 to be competitive within one of those programs.

Plan / Questions

I plan on purchasing the complete 5th edition of MGMAT study materials. With this, I plan on taking the next 2 months to spend 2 hours a night on weeknights, and maybe 6 hours each weekend.

Will this be enough time?
Any other recommended materials?
I feel like I have an average background aside from my entrepreneurial college experience- With this, I feel like I am going to need at least a 700. Agree? Disagree?


Thank you!
