history: I failed my Calculus exam despite having studied all nights. It was heartbreaking for me It was pretty shocking for me to learn that I have failed my Calculus exam when I had studied so hard for it Ahhh.  Math.  I have certainly been there before.  I am so sorry!  Is there any way to retake it?
current: Only next semester. I feel like I have wasted much of my time
next: Don't feel too bad.  I had to take college algebra 3 times before I finally passed with an A.  Sometimes you just need a good teacher.
