Haha I once got an E for A-level Biology, to be honest I put absolutely no effort into that exam, I went to a heavy metal festival for the 3 days before the exam and figured "f**k it, I'll resit it later in the year" so I just got drunk and did other various immoral activities that weekend. I wasn't in the best state of mind lol.
Anyways, very well done on your exams.
