I didn't think Cost Accounting was that difficult so I was beyond confounded when we got our group project grade. There was no way in hell I would get a B in the class unless I ace the final exam. That seemed impossible because it was one of those tests where you get carpal tunnel in the end from crunching numbers.
Then I got my final exam grade. It felt like one big joke on my ego.
Lesson learned: it aint over 'til the fat lady sings.
