Sandberg confirms that “A is Average” at Harvard. Her brother David, a neurosurgeon whom Sandberg admires because currently “he splits child care duties with his wife fifty-fifty”, was also a Harvard undergrad. He takes “a class in European intellectual history”, skips all but two lectures and all but one book, gets tutored for three hours and receives an A for the semester (p32-33). The guy’s success is attributed to the general confidence of men. Sandberg does not consider how likely it is that her brother’s confidence would have resulted in an A in a physics class at Caltech.
