Okay, guys, who likes facts? I sure do!
So first off, let me say, by all stats I've been able to find, application requirements for OD school ARE LESS STRINGENT than application requirements for dental or medical school. However, the differences are not that extreme.
The average GPA of students accepted to optometry school seems to be around 3.4, and the average OAT score around 320, or ~70th percentile.
The average GPA of students accepted to dental school is ~3.5, and the average DAT score ~19.4 (which is around 80th percentile).
The average GPA of students accepted to med school is ~3.7, and the average MCAT score ~31 (or about the 80th percentile).
With all this being said, are we REALLY going to judge one another on the numbers we received in undergrad? Is your statistical dental average of a 3.5 GPA all it takes to make you feel superior to others? If so, that is really, really sad. And the average percentile scores of accepted students to these schools is so variable, to use these numbers to compare our e-penises is just laughable, really. For example, the average DAT score of accepted dental students in 2009 was 17.9, or roughly 65TH PERCENTILE! Does that mean dental school applicants in 2009 were ~soooo much stupider~ than 2011's applicants? No. No, it doesn't.
In summary, WHO THE **** CARES ABOUT THE NUMBERS? Do what you love and be happy with it. The end.
