Hello Jon!

I'm planning to apply for HBS 2+2 program in round 3.

23/White/Male/Brazilian
Undergrad 1: Physical Education, GPA: 8.3/10
Undergrad 2: Information Systems, GPA: 9.1/10 (Class of 2012)
Post Grad 1: Especialization in databases in one of the top universities in Brazil (especializations are considered post-graduations here), GPA: 9.2/10
Post Grad 2: Currently studying a MSc in Technology in one of the top universities in Brazil GPA: 4/4
TOEFL IBT: 112
GMAT: 580 (!) 42Q/28V
Work Ex - Internship of 1.5 years in an IT company as a system's analyst. Was able to lead a small team (3 people) in some projects.
Co-founder of a small technology startup during 4 months (it didn't work out)
Currently working full-time in an IT company as a mobile software developer.
Extracurriculars: Did some community work, organized a few events in college that aimed to help people become more healthy. During college I was the coach of the soccer team during 2 years, and in my second year as a coach we won the local university soccer championship.
Also, I did the last 2 years of my first graduation simultaneously with the first 2 years of my second graduation. During the last 2 years of my second graduation I finished my especialization and started my MSC.

Why do I want a MBA, or more specifically, the 2+2 program at HBS: To enhance my knowledge in technology in the next 2 years at work and then learn how to manage and start companies at the MBA, so I can start a new company with the knowledge acquired.

Question :
My low GMAT score is my biggest concern here. There is only one month left before round 3 deadline and I still need to write my essays. So I have the option to prepare good essays and apply with a low GMAT score (and explain that the low score was due to not enough time of preparation, since I only found out about the 2+2 program a few months ago), or to prepare average essays and try to retake the GMAT (not sure if I can increase the score in so little time). What should I do?

Thanks in advance for reviewing my profile! Any advice will be much appreciated.

Thanks for the reply Jon!
I will retake the GMAT then.
