I understand that you must just have started to do your research into optometry school, but as a common courtesy to everyone else here, do some research on your own before you expect everyone else to do it for you. There is plenty of information on opted.org, and if you still have questions after that, try the schools' websites. If there are still some things you wish would be cleared up, do a search on the forum for your question and it has probably been answered a dozen times before.
If you STILL have questions after that, then post it.
