I went back to school 2 years ago (I am 53) and after working in accounting for 20+ years, I placed in beginning math LOL. I had to start all over and yes, I have struggled. I had a 4.0 GPA until I hit Intermediate algebra. It's tough, I still have one more math class after the one I am just now finishing. Good luck, enjoy your classes, I am betting you are going to love it. I know I do.
