Trisha, this is a great question and it's awesome that you are already thinking about it. Big schools have a lot to offer so hopefully you'll be able to align your activities / extracurriculars with your interest areas. Start by going to any orientation events that your school holds. Also, talk to your counselor early on and establish a good relationship here. She or He will be able to help guide you throughout your college journey and if you have a strong relationship, they will likely think of you when events come up that pertain to your interests. That said, college is a great time to explore many things. Don't just join clubs or get involved with things because you think they will help you get a job in a certain profession - I'd recommend trying a few different things. It's great to build your network, even outside your industry, and college is a perfect place to start. Have fun!
