Fear is normal. Jump in.

Learn how to learn. Get really good at that. That is the essence of your college experience. Perhaps consider a minor in a life science, hard technology, or other field that has good employment prospects.

Everything is software these days--it's going to be about applying software rather than pure programming skills.

Take a physics class or two. Learn how and why things work.

If your school has co-op work--do it. It raises your employment prospects at graduation.

Expect to have to consider multiple options/tracks in your career ahead. Adaptation and flexibility will be important. The world is changing quickly.

You can't study everything in college, but you will need to be ready to study and adapt in the years ahead. Good luck and do well in school.

One more thing: be social. Your network of friends will be extremely valuable to you.

> One more thing: be social

This is really important. I didn't appreciate it at the time. Get to know people in your classes, not just your roommate. Join a club, or check out greek life if that appeals to you. If you weren't very social in high school, now you're in a new environment. Nobody knows you, and nobody cares about high school anymore.

If you're introverted it can feel awkward but you're rarely, probably never again, going to be in such a diverse group of people who are all about your age and stage in life. Certainly not for four years.

Co-op every chance you get, ideally every summer. Start ASAP. Do not be afraid of off-summer co-ops.
