I’d say you’ve got a pretty slim chance of getting in. Given your ECs and work, I’d guess that you’re targeting their BME or something bio related, which are, as I’m sure you’re aware, among the best in the country. Hopkins is essentially an ivy in terms of admissions, and your stats, both GPA and SAT, are below their averages. I’d say it’s unlikely you’ll get in. Theres still a chance, although it’s pretty slim. Good luck regardless.
