In general, the OOS acceptance rate of up to 30% at Maryland is actually quite generous compared to other state public universities. Depending on which state you are from, being OOS could actually be a hook rather than a disadvantage. What I mean is that they want geographic diversity represented in their OOS admissions. Fwiw, Maryland tends to be a particularly popular choice for students in NY/NJ/PA/VA. So, if you are from the midwest, for example, I’d say that being OOS status is actually a good thing.
