Least “weedy” would be Centre and Loyola Chicago. There’s attrition due to students who can’t make it or find other interests, but no necessary, deliberate culling.
UMAss and NCSU are huge public universities : they don’t have enough space for all would-be premeds, so weed-out is necessary. There are very large classes and only those who BOTH work very hard and are smarter than 80% in their class have a real shot. A good indication would be if you got into the Honors college at either one. If not, probably not a good choice.
Don’t major in Biology. There are few positions for biology majors (most positions require a Master’s) and an oversupply of them that even before the pandemic the job market couldn’t absorb.
Furman and Baylor are politically conservative; this would matter if you are politically active or if you aren’t into politics.
In addition, Baylor is Baptist and takes faith seriously, with religious requirements (you don’t have to be Baptist but being Christian helps with the requirements). If you’re not serious about your Christian faith, it’s not a good fit, but if you are, then it could be a great choice.
(Be aware that some students mistakenly believe Baylor undergrad is linked to Baylor medical center, whereas it’s 1H30 away and undergrads never set foot there.)
What’s your net cost at each?
