I’m not sure if this can be applied to students who take multiple advanced classes simultaneously. Some individual physics problems can take the average student at least 30 minutes to solve per problem; I can’t see anything beyond mindless plug and chug problems being assigned if you tried to fit AP Physics C homework (along with all the other classes) into a 70 minute time period. Similarly, I don’t see how an assigned novel to read will be finished in a reasonable amount of time.
