Hopefully you can use it on the final.
Math is one class I don't care about. I have 28 of 31 available marks so far, and so I need 22 more out of 69 to pass. I don't need a good mark in it because economics doesn't require calculus. Or really math. Seriously, this class is half of what you learn in the science stream's 1st-year calculus class, except taught easier, and yet it's the class they "strongly urge you to take if you're going on to graduate study".
Sounds like you'll probably manage to pass. Also, you don't ever really need a good mark in anything as long as you pass*, because no worthwhile employer ever is going to ask. *Exception being, as you note, going on to graduate study...
