Hello all,
So i'm in my first semester at university and I have a negatively marked multiple choice module test coming up and just wanted some advice on approaching this!
Here's how it works for my test
4 options per question
Correct answer = 1 mark
Incorrect answer = -1/3 mark
So my thinking is if I don't have a clue on an answer I may as well just guess. This is based on some simple fractions.
Say I guess on 4 questions, there is a 1/4 chance that i get each one right which would result in the following marks.
1 correct = +1 mark
3 incorrect = -1/3 + -1/3 + -1/3 = -1 mark
Overall = 1-1 = 0
But, I also just thought, if I stand to gain no marks on average is there any point in guessing when i have no clue?
Would it be better not to guess at all and if I have to guess only do it when i can narrow down the odds to say 1/3 or 1/2 so I have more to gain.
Any help or suggestions would be much appreciated - if you have experience with these especially so!
Thanks Jack
