i imagine this is why our guys take summer courses, to help alleviate some of the in-season pressure.
Most schools make their kids take summer classes...
It is often done so the kids can only take 12 credit during the school year. If they only take 12 credits per semester while in school and play four straight years with out attending summer school, they will be VERY short of credits to graduate on time. The summer school helps them catch up to be on time to finish in 4 years.
