It was a surprise to me, but state college was much harder than I thought it would be.
Why were you surprised that state college was so hard?
I didn't think it would be much different than high school.
College is for serious students and the material they expect you to learn is more difficult and challenging to learn. If you study and work hard you'll be able to do well.
I feel overwhelmed and we're not that far into the semester. I'm not sure if I can do it.
I know it's a challenge but you'll do well if you work hard. If things are too much for you, there are services on campus that can help you to budget your time and give you extra help to keep up with the class materials you need to learn.
