I am currently taking calculus 2 and I am pretty certain I just failed a test. I got a 98 on the first test and a 100 on the second. I am pretty sure I got around a 60 on the third test and I don't plan to make any excuses for this failure because it was due to my own bad decisions. I am confident that I can get a 95+ on the final.

What I am worried about is if the A- in this course will affect my grad applications in the future. It seems unfair that one stupid moment will limit me but I also realize that when engineers make mistakes people die or in this case mistakes lose a lot of money.

I don't plan to repeat this mistake ever again but what's done is done. Will this affect my application for grad school if I get an A in everything else? Not sure if it makes a difference but all my math courses are honors courses. All the math courses I have take are completely theory and proof intensive. All of my future math courses will be the same.

I plan to get my phd in mathematics. The reason I am asking on this forum is I hope to apply my phd in some way to finance. What do you think?
