I'll gonna do a law exam in a few days, and I need your help
The test is a 120 questions true/false, 1 point for each correct, and if your answer is wrong, you lose 1 point.
If you leave it blank, you dont lose nothing.
My question is: based in probability, what's the best option? Answer all that I dont know or leave it blank?
THanks in advance and sorry for my English™
