Question about SL psychology final

[tsimmns]

First off it's closed book, which somewhat sucks, however it is what it is. Right now I have approximately 591.5 points with 700 needed to pass. The final is 60 questions worth 300 points. I assume that leaves each question worth 5 points leaving me needing to get approximately 21.5 questions right to pass the class. Are my calculations correct or am I off? This might not end up being a click through final like I was hoping it would be.
