Two things:

1. I was surprised at how much more freedom we had than in high school. Most teachers didn't have rules about attending classes. It was to your benefit to go, but they didn't harangue you about it if you didn't show up or grade you down for skipping. (You might get graded down for lack of class participation if you weren't there to participate, but you weren't scolded about it.)

2. Once I saw how large some classes were, not just freshman lectures, but all the way up to grad-level courses, I was amazed at how approachable almost all the professors were. They were so willing to help, to answer questions, to discuss, and so friendly and not at all intimidating. I only had one who preferred students to use his teaching assistants. He was polite about it, but he had a weekly TV show besides his teaching and research, and said he just didn't have the time for routine questions. But all of the others were great. Even one who wasn't my professor saw me waiting in the hall with my textbook and offered to help. My question was about the book, and it turned out he was one of the authors, so I got perfect help!

I can't remember any single thing that suprised me.

It's very different from high school. I was expecting that.

There is little to no homework. Grades are based on tests, papers.

You are very much on your own and need to self-manage. Building a structure to your life is essential. If you come from a structured family, you will do better.

Otherwise you will have to ally your life. Build good things against bad (disliked) things. That is the means to succeed.

If you have some faith in it, if your financially secure and all that you will be more confident.

It's personal, really.

Best of luck. Get laid ;)
