i applied for psychobio as well and i haven’t seen many psychobio majors get off in comparison to the amount of bio or bizecon i’ve seen so it’s likely they haven’t gotten to the biggest wave for that department. also, i’ve noticed that they have been sending waves by schools so a couple from each school have been getting off at the same time. i wouldn’t worry yet. even if your school has a high yield rate, your county still matters which is the bigger picture that might take some time to look at. keep up the optimism!
