Not everyone goes to college, and there is nothing wrong with that decision. But those who do usually have a, "Huh, this is harder than I thought it would be," at some point during their first semester. You are used to the somewhat flexible due dates of high school and only needing to write papers in MLA format.
Then you get to college and if you turn something in online .3 seconds after the time it is due, you lost points or fail the assignment. You find out more about APA format than you ever wanted to, only to learn that you need to write one paper in MLA or Chicago format. There are certain struggles unique to residents and commuters alone. But without a doubt, even if you do not want to admit it, you struggled when you first started out.
There are a thousand and one different ways that college can overwhelm you, and most of them happen at the same time within the same week. You have syllabi and assignments thrown at you from every direction. You're trying to make new friends and maintain relationships with old ones.
You have not found all of your classes or the bathroom yet. Ya know, everything that goes with being thrown into a new environment.
It's now January, and you have received your first semester grades. Are you 100% satisfied? Maybe you are, but did not give yourself time for extracurricular activities and still feel like a nobody at the school. Maybe you gave too much time to your extracurricular activities and not enough time for school work. Either way, guess what? You are not the first, and you certainly will not be the last.
You live and you learn, right? Not every class is going to have the perfect ending. Communication is so much more important in college than in high school. Chances are the, "'I left my homework at home," or "My dog ate my homework," excuses really will not work anymore.
Check back on yourself at the end of next semester. If you see a change in your results, good for you! If not, take a look in the mirror and realise it's your own fault. Make the necessary changes. This is YOUR life and YOUR education.
