Ask any college student or professor for advice about scheduling, and more often than not the first thing to come out of their mouths will be "For the love of God, don't sign up for any 8 a.m. classes." Early morning classes have a ghastly reputation on college campuses, and maybe, to an extent, they deserve it. I don't know of anyone who would prefer waking up at 7 a.m. to go to class instead of sleeping in, and doing this multiple times per week is no small feat.
That said, it's often extremely unlikely that a college student will make it four years without having to sign up for a single 8 a.m., especially since underclassmen are often subject to later registration times and tend to get the "leftover classes" that no one else wants. So, to the college student who unwillingly took an 8 a.m. and is devastated because everyone under the sun insists that they are the scourge of the Earth: it's not that deep, and they aren't that bad.
Early morning classes force you to wake up at a decent hour and start your day, and they can tend to make you feel more productive throughout the day because of this. Sure, the first couple of times you do this are going to be tough, especially if you aren't accustomed to being up and productive at that hour, but it doesn't take long for waking up early to become a habit. Taking the first class of the day also means that your professor is more alert and not exhausted from a long day of teaching, so you'll most likely be attending the most enthusiastic lecture of the day. Morning classes can also help to ensure that you're done with your day by early afternoon depending on whether or not you schedule your other classes at early times; for college students who work or do sports, having a whole afternoon ahead of you once you're done with class is actually really convenient.
No, an 8 a.m. class isn't the first place you'll want to be after a late night out, especially if you aren't a morning person by nature. You probably won't learn to love your 8 a.m., even if you enjoy the perks that come with it, but it really isn't as bad as everyone makes it out to be. Do your time, show up to class, nap later in the day if you need to, and if you really hate the time slot you can always hope for a better schedule next semester.
