Maryland doesn’t prioritize in state like some schools do (unc, ecu, etc) but if you look at statistics in the past years just under 40% of in state applicants that apply end up actually going there. Considering the in state students who got in and chose other schools and students who didn’t meet requirements/weren’t competitive I think it’s safe to say most in state students who apply probably get in. Also usually the class is 50% in state and 50% out of state, with about 150-200 applicants being from md and 2000+ being from out of state. So way less people competing for the same amount of spots, so I would say in state people have an advantage for sure but not like some of the other schools
