Calculus III - it sounds really hard

Phil is taking Calculus III this quarter at Kalamazoo College. As someone who only took pre calculus, this class sounds really tough. Phil is very gifted in math and I know he will do great. I don't think anyone else in our family has taken such a high level math.  Way to go Phil. To keep some balance in his life, Philip is also taking the history of the British Empire by Dr David Barclay. Dr Barclay is a wonderful lecturer who always gets the highest review from his students.  Should be an interesting class.
