Finals are coming up..

at the moment im just trying to get to the end of the year without failing any of my classes

in high school, i did advanced mathematics, but i could never write the workings out, just the answer, the teacher said i had to show how i got to the answer, so i just wrote the answer, then filled the "workings out" with bullshit. I got questioned about how i came to the answer, which was correct, and i just winged it making up shit as i went along to get to the end.

I did a smart-arse answer in a test today, planning on going back at the end to actually think about the answer, but I forgot to in the end oh well

I once had a test question on a chapter about sound. The question was: "I have a large standing clock wich makes a lot of noise, when I want to sleep I can hear it from my bedroom, how do I fix this?" The right answer was something like isolating the walls. I really didn't know so I wrote down, throw this one away and buy a new one. My teacher accepted it because it was a right answer. (Tl; DR I wrote a bs answer and it worked)

Sometimes when I really don't know an answer on a multiple choice test I just start weeding out the ones look dissimilar to the other answers and then pick the one that looks best on the scan-tron. O.o
