yes I failed a biology lab midterm I literally got the lowest grade in the class but then I made my Britney 2008 circus comeback on the final and got a B in the class
I failed my AP Chemistry (or was it Psychology) class in high school because me and the teacher couldn't get along. I remember that last month of school I just came in and relaxed and socialized. Everyone knew I failed that class and I didn't care lol.
I failed my Business Management prelim for my Highers, but only because the teachers marked exactly to the marking scheme, whereas the in real exam, other correct answers not listed on the marking scheme would also be accepted. In the final exam though, I got an A (and I did so for my other 3 Highers too; Maths, Latin and Accounting). Since going onto uni, I've not failed any component yet.
