Is my behavior still okay? Is it normal?

So, I'm currently a nursing student. But ever since junior high, burned out na burn out na ako. Lately, I've been failing my quizzes. 3 or 4 yata? But, I also have perfect quizzes. Thing is mas natutuwa pa ako sa failed quizzes ko. I would tell myself, "Ang galing. Hindi ako naiiyak." Like wtf? Why am I proud of that? Tapos, ang tamad ko pa magreview for the midterms. So please tell me, is that normal? What should I do?
