Thanks for the help!

Thanks!

It's been far too long since I've had a math class, and here I am in Calculus I. Fortunately, the TA has agreed to spend a few hours with myself and other students drilling (into our heads) the concepts from algebra, pre-cal, and trig that we've forgotten. If only he'd find a room we can use...
