You will find that the first degree that you enter into at university isn't the one you necessarily come out with. ALOT of people change their mind - e.g. loss of interest part-way through. For me, I was always fascinated by computers and how we can create interesting and helpful tools with code. My path into university was a no brainer, and I've never been more confident I made the right choice.
I think the important thing is an interest in your area. It will be a long 3-4+ years in the same degree if you don't have an interest in the content. That's why I suggest the first semester at university is ultimately a taste-tester, to get a grasp of the content that you will further develop in your degree. If you find that it isn't your thing, you can always internally transfer to a different major/degree/whatever (usually means that you'll have to start again - in most cases).
