“a typical GPA for a lower division course will fall in the range 2.8 – 3.3.”
Reminds me of a year where a teacher of mine (high school) gave everyone in class an A. He got called on it, and fought back. He literally called out the weakest kids in the class and had them do the work in front of the admins complaining and said, "tell me that's not A work, I ["fucking" strongly implied] dare you."
His grades stuck.
