I think for the diversity part, we can go over 1 page double spaced. The 1 page double space limitation is for the "why UW" prompt specifically.
As for the RIDE question, I'm not doing it and I don't believe it will affect your application. It states that RIDE is considered post-acceptance.
It doesn't say anywhere on there that we have to limit question/prompt 1.) to 1 page so sleepy is right. I went two full pages on it. But yes 1 page double on question 2.)
I do know that it says applying for RIDE will NOT help your chances but here are my thoughts on that:
According to the 2010 ADEA Official Guide to Dental Schools there are only 246 in state applicants and 56 in staters are accepted. Of those 56, 10 or so are enrolled in the RIDE program.
UW says that they pick their top people and then place people in the RIDE program after the fact, but I have a hard time believing that of the top 56 people, 10 of them will have selected RIDE.
This means that the would have to remove the bottom few applicants and replace them with people who wanted to do the RIDE program.
Long story short, I know that they say that selecting ride won't help you but I can't help but feel like it might.
