If guesses incorrectly on 12 questions, maximum gain is 12 points but maximum loss is only 3... BUT if all of them are skipped, there's no chance of the raw score improving. I'm answering my own question here...guessing is probably best.

But then what is your chance of getting it right? 1/5
while your change of getting it wrong is 4/5
So for every 5 questions u guess, 1 will be right thus +1
but 4 will be wrong, thus 4*(-1/4) = -1
So you come out with 0
