A lot of new Uni students are uncertain and don't know what they really want to do. Fortunately you're just starting out and have plenty of time to test the waters and change your major if you do find your niche. Idk about where you live, but in uni here there are gen ed classes that are required for many degrees so if its that way at the uni you are going to I would take as many of those types of classes as you can while you are still figuring yourself out.
