O god these questions remind me of those horrible Thermodynamics and engineering mechanics test i have to do at uni. I had another mental meltdown in one of the test and wrote "No fu*king idea, just fu*k it", (i wrote the actual swear words down). As a result i lost the 1 and only mark i got, got a fat zero and the marker wrote an essay on my test paper, saying how i should not swear on the test paper and i have to go and see the lecturer. Naturally i burnt the paper once i got it back, and i didn't take a photo cause my parents will kill me if they saw it.
