The advice that I've been given on this subject is to guess on any question that you can eliminate the choices down to 2 answers.
If get 150 questions correct, guess on 25 that you were able to narrow down to two choices, and leave 25 blank, you will, in theory, have 12-13 questions correct, and 12-13 questions incorrect, netting you 9 or so raw points higher than you would have if you left them blank.
You could get all 25 wrong, you could get all 25 right. Its a risk, but the question is, 'Do you feel lucky?' (or do you believe in probablilty theory at all if you don't believe in luck?)
Also, according to probablility theory, you'd have a 1/5 chance (since there are 5 answers in the multiple choice) randomly guessing on problems, which would still equate to the probability of 10 correct out of 50 random guesses, which would put you at an approximately 150 raw score if the numbers hold up. (the same amount that you would have had if you didn't answer the questions.) And of course the probability increases if you can narrow down the answers to 4,3, or as discussed up there, 2.
But that being said, I'd stick to guessing on the problems which you have a 50% chance of getting correct.
*Edit - And if you think that's bad, you should know that ALEKS Statistics has ruined Yahtzee for me.

Allow me to introduce myself. My name is Wile E. Coyote, genius. I am not selling anything nor am I working my way through college, so let's get down to basics: you are a rabbit and I am going to eat you for supper. Now don't try to get away, I am more muscular, more cunning, faster and larger than you are, and I am a genius, while you could hardly pass the entrance examinations to kindergarten, so I'll give you the customary two minutes to say your prayers.
