You would automatically get the Curators Scholars Award ($5K) from Mizzou, which puts you within budget. You have some other good in-state options as well.
I can’t see a compelling reason why you would choose an out-of-state large public over Mizzou for biology. Unless the cost ends up being cheaper somehow. And as mentioned above, you can opt for a different in-state school if you want something smaller.
If you go into biology research/academia, you won’t pay for your PhD. But it is still smart to minimize undergrad expenses – don’t go into debt.
Mizzou is a gem. It has an agricultural school, a med school, a vet school, straight up “biology”, and several other bio-related fields. You can study (and do research on!) just about any aspect of biology your heart desires.
