I would question that test. If it's the one where you look into a box and have to pick out floating circles, a lot of people have trouble with it even if they don't have any depth perception problems, myself included. It is like reading magic eye, it's about the right technique as much as it is about having depth perception. There is another test where you wear funny glasses and read out of a book that works a lot better. Either way, you can get a waiver for it. There are plenty of other threads on this site about depth perception if you try the search bar you will find some more details.
