>Keep in mind also that that's because in high school the number of hours per week are far more limited. I don’t understand what you’re claiming here. At least in terms of classroom contact time, the number of hours is much higher in high school (typically five 50 minute periods per week vs. three 50 minute periods per week in college) and the school year is longer (20–21 weeks per semester vs 15 in college).
