You got this!! As others have said though, don't worry if you don't have things figured out. I studied sport at college, then went onto sports psychology, then tourism, then marketing and now customer service so don't feel like you need to stick to one area!
If you are unsure, you can always give universities a call to discuss your options, I'm sure they would be happy to help talk through how they, and others can help support your journey!
It might seem like a long way away, but do you have any careers in mind for after uni?
