Q SCI 381 and ? for SAFS majors

Anyone taken Q SCI 381 - Intro to Prob and Stats? Is it hard? How calculus-based is the math?

Also, are there any Aquatic and Fisheries Science majors out there who can tell me if there is an alternative stats class that I can take to fulfill my math reqs? I've taken MATH 144 and am in MATH 145
