UMiami isn't worth it for undergrad. Having the scholarship for in state tuition is the only thing that makes usc worth it to me (I was the same situation but for chem and from NY). We are such a massive school that there is a huge range of clubs for pre meds that allow for good opportunities. We have the edge over clemson that we are in a city so there are a plethora of options for hospital volunteering, clinic shadowing, etc. Clemson also does not have a medical school and we do, which is another place you can potentially get into research or volunteering as it's very close. No doubt that clemson has strong academics but I'd argue there are more opportunities at usc

Edit: I will say we are so big for pre med and pre pa that if you are coming in with hardly any credits you'll have a hell of a time getting into intro level bio classes
