The lowest grade I have ever got in a subject that I actually had any enthusiasm for was a "C" grade.
However, I got an "E" once in technology at GCSE level, I absolutely depised that subject and never revised for it, and I hated the teacher as well. In fact, I remember telling my Dad that I never learned anything in his lesson as he was always flirting with the girl's instead of teaching, funnily enough two month's after I left school it was in the local paper that the very same teacher had been found guilty of two counts of indecent assault against a 14 year old, and also guilty of the possession of child pornography on his home computer.
I've only gotten A's and B's in school throughout my life except for one class.

I got a D in that class because i didn't do any of the work or study because it was up to me to organize my time properly. I should have dropped it before I got in too deep but again....i didn't organize my time properly
