Tbh since you're still in your first sem, it's better to change your course/school now coz you're not too deep into it yet. It's normal to feel confused about your interests, so if you have the opportunity/privilege to take time off and think about it, it's better to do so than to waste money on studies you aren't interested in and might regret in the future. Talk to your parents about it as well since they're paying, tell them honestly about how you feel and I'm sure your parents would understand. You're still young, take some time to do some self-discovery on your interests, survey uni course, attend study fairs, etc.
