Welcome to Gaia! ::

I am not very smart and I am honestly fine with it.

Just keep your head up, and have more confidence in yourself! Go to class on time, pay attention in lectures, complete your assignments in a timely matter, study for tests, midterms and finals and seek out extra help. Colleges often offer out out class help, ask your professors what their office times are, you can set up appointments with them to help you catch up on what you don't understand, it really isn't that hard so you should stop worrying, you'll be fine. I'm not the smartest academically, especially when it comes to math, but I went to every single out of class session that I could take, and I graduated.

nobody starts out knowing a lot, that is the whole point of studying. you can always do your own research on things, ask people in certain careers/jobs for suggested books to read on what they do, or you could talk to them, to find out what you're interested in. that will get you started but you will still need experience, and if you don't understand something you need to figure out how you need help.

It's normal to feel this way. I'm 20 and will be returning to school in a year so I'll have been out of school for 3-4 years. All you gotta do is try to teach yourself and if worse comes to worse try for a few more grants/scholarships so you can take some remedial classes.
