Rich,
Thanks for reaching out. I agree 680 is a respectable score, but it is towards the low end of the 80% range for my only target school, Columbia. Their value investing program is second to none, I grew up and live in New York and I'm keen on beginning my studies in January. Additionally, I feel the math score is significantly below my abilities as I was scoring much better going into the exam. I would love to be able to send in my application as is, but a score at or above the school's average (around 720) would be preferable in my opinion. With that said, I do feel I have a number of advantages, including my age and experience. I have been an equity research analyst on the buy side since I was 21 years old, a unique background in my opinion. Additionally I have ties to the school through colleagues and bosses. I'd be curious what you think....
Regarding to your questions:
My last two GMAC CATs were full exams (essay and IR included). Each of the exams were taken at a similar time of day as the official test (within an hour or two). I took them in the library, which was considerably louder than the test center. Given that I wanted to take the test once (I only decided to begin this adventure towards the end of April) I decided it was best to purchase a package of exams so I could truly gauge my 'progress'. So none of the exams were repeats. In my next go round, I too will use new exams for the same reason.
Judging by your questions you're trying to see if I did anything on test day that significantly deviated from my prep routine and honestly, I did not. I prepared for the exam at that specific time, had similar meals (the exam was about an hour to an hour and a half earlier then I was taking the practices...this go round it will be almost the exact same time), etc. For those reasons, I feel like I "choked" to a certain extent. I'd love any additional thoughts you may have. Thanks again.
Anthony
