Is it normal to be clumsy and akward when called on

Omg I act like a complete idiot infront of my crush, it's like Whyyyyy

If you want to impress your crush you should try giving the right answers when the teacher calls on you. But you should also sometimes mess up on purpose, because guys think that's cute and because guys are scared of girls who are smarter than them.

Since i was young i was bullied and im tired of it

I do focus on class

Maybe invite your crush to fuck the tight little asshole of a cancer kid with you? Might help bring you two together.

Perhaps a bit more of your time in school should be spent paying attention in class rather than worrying about your crush, and THEN you won't feel so AWKWARD.
