The guys in college are no different than the guys in high school. Most of them are immature, hollering at every girl that crosses their path and making school a joke. There are some guys that do take their education seriously and that are mature, but these types of guys are usually seniors in college or graduate students.
Girls, on the other hand, are slightly different than the guys. Of course, you have the girls that are loud, uninterested in academics, and overly obsessed with their appearance. But there are more girls than guys who academically thrive, and are focused, motivated, and mature.
