Well said @humanearl. I totally agree with what you have said. Just to add to what you have said, an advice to @blessing2002 is that from experience, the likelihood that you're the first student on your campus to be struggling academically is, well, nonexistent. That means, of course, that there are places you can go for help.

First and foremost, reach out to your professors. While going to office hours and talking to a professor might be scary, remember that they, too, were college students once. Talk to them about your struggles. Ask them what guidance they can give you, whether it be the name a tutor or the offer to look over your work before you start working on your next paper.

Additionally, talk to your academic adviser. If you're too nervous talking to your professors, you adviser can be a great resource. He or she might know other students with whom you can form a study group; they might have some tips on how to do better in a certain professor's class; they might help you come up with an action plan of how to better manage your course load.

Your campus likely also has some kind of academic support or tutoring center. Use it! It's part of what you pay for in your "tuition and fees." Even if you aren't sure what kind of help you need, stop in to see what it has to offer. From peer advisers to faculty tutors to help with time management, an academic support center is a definite must-see.

I hope these tips help.
