I'm sorry, I believe that looks like a multiple choice exam... It's really impressive to get 3/50 on a multiple choice exam. Like, assuming four answers per question, the expected result if you randomly guessed everything is 12.5/50. 3/50 is 6%, which is about a 1/17 correct answer rate.
And it looked like the first question was a true/false or A/B question, while questions 2&3 were ABCD, so we'll say the questions had about 3 answers on average. If randomly guessing, the odds of getting 3/50 on that is about 1/700, if my math is correct (which it probably isn't, but it's still extremely unlikely in any case)
