I have been a nursing assistant for the last 4 years, as well as having worked in a group home (dealt with numerous psych disorders- for a year), while also being a college athlete. Looking for adcoms opinions on how much these things actually help me? I have a 3.78 GPA and a 517 MCAT (128/128/131/130). Yet I only have 1 semester of research experience (did organic chemistry research). Should I even try applying to top 20 schools or should I aim at in-state schools and mid-tier private schools? I'm starting to write secondaries and figured I should ask since I've heard that the majority of top 20 schools desire more research experience than what I have. Thank you!
