how difficult is Geneseo?

My son is considering Geneseo and his only concern is the distance from home but i have a concern about how rigorous it is. I know several kids from town who had wonderful grades and scores and they are struggling at geneseo? My son loves academics so I will be surprised if he flounders but just curious about the demands of the science programs there?

I am an accounting major so I can’t give the best opinion on the science program. But to my understanding (most of my friends being physics/bio/biochem majors, the courses are rigorous. Nothing that can’t be handled, but don’t necessarily expect all A’s.
