There isn't an AMCAS sort of system set up if that's what you were thinking- each school has it's own app (at least to my knowledge). I don't know about the other schools, but SGU has an application on their website. You can download it and send in the paper copy- or you can choose to do it electronically. There is also a 'contact' page where you can ask to be sent information. I'm betting the other school have similar set ups. Check the websites.
