Only if his schedule permits him to go to the dining hall for all 21 meals, and it may not.
College classes and activities are not necessarily scheduled in a way that allows students to go to the dining halls for every meal, and dining halls are not necessarily located in central places that students can easily get to during the day. Also, an hour may not be enough time for a student to walk to the dining hall, get through the line, eat, and get to his next class. So a student who has, say, a class that ends at noon and another than starts at 1 p.m. may not have time to eat lunch in a dining hall.
One other factor: College students tend to conduct their lives on relatively late schedules, but dining halls serve food at conventional times. Masses of students rarely or never eat the breakfasts they have paid for because they’re still asleep when breakfast is served, and they also find that they’re hungry late at night, when the dining halls are closed, so they end up spending points or cash on evening snacks.
Minimize the meals. Maximize the points. You won’t be sorry.
