I'm going to turn this into a stupid mistake by the examiner:

On my geography mock paper I was finished about 40 mins before the exam ended so I wrote pointless facts on the back of the paper from QI. For this, I got an extra 20 marks and she commented "Useful information, please remember to clearly show which question you are answering as there was some confusion with this answer"

Brought me up to a C so yh okay....

I couldn't identify the third GRASP pattern in my software systems engineering exam recently. I knew there was a facade controller, role controller but couldn't think of the other one for the life of me. I could even describe the other two well. I'd revised it loads as well :\

I chose the wrong question in my Jan politics paper and ended up doing quite bad.
