I haven’t been paying much attention to Harvard since graduation, but I was class of ’09. On Math 55: very disappointed to hear this. AFAICT they still have 5 different intro math sequences (multivariable calculus + linear algebra; Math 1a and 1b are the equivalent of AP Calculus AB and BC and most skip them) with different levels of rigor, so I have to wonder what Math 19, 21, 23, and 25 are now like. I took 21 and wish I’d taken 23, because even in 2005 I underestimated how much watering down had already happened.
