Ranking does in fact carry weight during the admissions process. Top tier schools can be more selective, but the "bottom" tier programs can sometimes be harder to get into than you think. With your stats, I'd say you have a pretty good shot at Northwestern and UIC might be a toss up. Are you an Illinois resident? My advice for you is to get some more hours in a different setting like inpatient or a SNF. By the way, can I ask about your outpatient neuro? I love neuro and do a lot of inpatient with SCI, Stroke, and Neurodegenerative, are you at a specialist's practice or a company??
