No - you should definitely call all the admissions offices individually. Nobody should be afraid to call an admission office ever - they are there to field your questions and check on things for you. If you don't receive an email from a school within a few days, call them just to check the progress. If you haven't heard from them for awhile about the status of your app once you know they've received it, call them again. Continue to do so every week or two (depending on the feel you get from the school). That shows interest. And if a school is not friendly to your inquiries, then you probably don't want to go there because either (a) they're disorganized and will screw things up for you repeatedly or (b) they don't have staff that cares for the students and their well-being. I know of very few optometry schools that fall into those categories! Most are really receptive. They want your moola.
