So here's my story:
I went to undergrad at a good Liberal Arts school in Connecticut and majored in psychology. The only undergraduate quantitative course I took was statistics and I got a C. On top of that, I did very badly in the first half of school, meaning I actually have an F, a D, and two C minuses on my transcript in addition to the C in statistics. I know some people may think that I cheated and that's why I got an F, but that's actually not the case - I earned every bit of that F with lack of effort, and I can show that because I have no academic dishonesty on my transcript (academic probation is another story).
Starting in my junior year, I really pulled my act together and the rest of my story looks great. I got a GPA above 3.5 in the final three semesters, and was able to improve my GPA to 2.9 by the end (believe me - it was much lower before those three semesters).
My GMAT is 760, 49Q/44V so obviously that is good, and I have 5 years of solid work experience. Currently I am a product manager at a brand name company managing a technology platform, and before that I worked as an analyst in market research, so I have a lot of experience with statistics and technology.
I want to work in product management for tech startups in NYC, Boston or Silicon Valley, and ultimately want to leverage that experience (and what I learn in business school) to start my own company.
So my biggest question is how can I offset or explain the bad grades, especially the F? Would taking a course in Calculus and getting an A help offset the lack of quantitative academic achievement and show that I am serious about addressing my weak spot? Or would I be better served saving my time and money and writing about it in the optional essay? And if taking a class is the route to go, would Calculus be best, or Finance/Accounting?
Also, what would you say my chances are at top schools like Sloan, Berkeley, Tuck, Duke, Michigan, Yale, NYU?
Thanks!
