I have a geometry question?

Well this a question about my grades... I'm a 7th grade middle schooler and I would always get A's on my math quizzes and tests. However, when we went to study the geometry section, I failed... HARD. At first, my score in math was a solid A. After taking a test (I got a C on that test), my overall grade dropped to a B. I determined to get a better score on the next test, but I forgot that we had a quiz and didn't study for it, even though it was hard for me. (yes, its alllllll myyyy faullltttt i hate myself ): ) I got an F(53%) ON IT!! I was so disappointed in myself.... :,( I think my overall grade dropped to a C.... In my math cl quizzes usually count as 100 points while the whole chapter tests count as 200 points.... Do you think I can get an A on math before the end of school? I have 4 months left......................... ALSJFWEIHO;JBA;LGV I HATE MYSELF....
