I'm a junior in high school who has always loved math. Over the course of the past year I have been working through a proof based ODE+Linear Algebra+Calc 3 accelerated course. I Was very proficient when it came to the proof based questions I was doing fairly well, averaging in the high 90s on quizzes and homework, I also felt very confident on all the topics in Linear algebra and ODE. But in contrast to this my problems arose in calc 3 where I often made trivial arithmetic errors and struggled a fair amount with the computational side of things Which ultimately lead to me getting a 91% (AB) in the first semester and an 89% (B) in the second semester. I'm just wondering if I was really struggling with those concepts am I really cut out for math?
