How can I find out if my brain is big enough for studying physics?

I'd like to major in physics but I am not sure if I can do it. I get the literally best grade only in both math and physics in school but what we do is just piss easy. I am just unsure if I can take the complex abstract stuff. How can I assess my intelligence to decide whether I am smart enough or if I should rather go for a engineering meme degree?
