Yes, but not by this particular change. Black isn't harder, it just covers more fun side topics, by skipping some intro material. This is better for everyone--more prepared students don't get bored, less prepared students don't get intimidated.
Mudd's general new philosophy of acquiring female students at any cost, however...that's another thing. Not to mention people who should know better subsidizing "research" positions for freshman women to build glorified websites.
