don't do the test
make a list of like 5-10 things you think you might enjoy and then do whatever it takes to get in contact with successful professionals working in those fields. your parents might have a surprisingly wide network of people, but also even just like cold-emailing on linkedin and being like "hi I'm ____, I'm interested in a career in ____ and I was wondering if I could buy you a coffee/lunch one day somewhere near your office and talk to you about what you do" would probably work well for you.
also, what are you doing right now whilst you're off school?
if you're just working some throwaway job and you have a while left until you go back, I'd encourage you to try and get some kind of physical labour-esque work. construction, landscaping, roofing, doesn't matter. there's value at a mental level in having to really fucking work hard for a living, for a while (your resto/coffee/retail job is tiring, sure, but its not actually hard), and you might find it satisfying. gives you good perspective on life, I think a lot of people would benefit from it.
