I was accepted to NOVA last year (I chose NOVA vs. ICO), and I have to say that it is true that the school doesn't have very high part 1 board passing rates, but they are working very hard to improve that. THey are adapting many new things, and what I LOVE so much about this school is that they care about what students want (unless one's a weiner, weiner's don't do so well at NOVA). THey ask us what we think would work for us and try to work with us. People are very polite and I love their professors they really care that their students do well, all you have to do is go and ask for help if you need any.
As far as the weather is concerned, it is not bad. Most people from the north they imagine Florida this "boiling piece of land" but it is not like that. During summers many other states have hotter weather than Florida, at least we have good AC's here that run all the time. You can go to the beach even on Christmas day, and get a tan.
The living expenses, well, I must say that it is by far less expensive than majority of states with optometry schools, have you looked at ICO rates or New England college of optometry?
Bottom line, doesn't matter where you go to school, all of them have strong and weak points, you need to make the best out of it wherever you go. You could graduate from Harvard Medical school and be the worst doctor that ever existed. It is all how much talent you have at being a doctor and all you need is for a school to present this information to you, the rest is up to you.
