I'm a Junior in High School as well, and I failed both semesters of Algebra 1, first semester of Geometry, and I'll probably fail this semester of Algebra 2, though I can't be sure yet.
Point is, I SUCK at math. My classmates giggle at me that I get like 50% on quizzes and tests, and that I don't even have a GRASP on this sh*t. But one thing I know for sure:
I'm not stupid, because I do really good in Science and Social Studies courses. English courses are also fun because I get to read & write; something I love to do.
If I have many strengths, I have to have one MAJOR weakness: Math. F*ck math.
