2. taking early classes:
some freshmen try to fill up their schedule with late classes so they can sleep in. this is a mistake. you should try to take early classes for several reasons. first, they usually have fewer students in them (always a good thing). second, it will keep you “living responsibly,” going to bed at a decent hour and feeling healthier. third, having early classes frees up the rest of your day for fun activities, more studying, or working at a job. early classes are especially valuable in the springtime weather.

why does the author suggest that a college freshman try to register for classes held early in the morning?
a) because it frees up the rest of your day for other activities
b) because everyone knows early morning classes are more exciting
c) because students are more attentive and awake in the early morning hours
d) because classes that are given earlier in the day are cheaper than later ones
