In good conscience I must make a distinction: my public school complaints were the direct result of regressive policies on part of administration. Many of my actual teachers did the best they could with ridiculous constraints.
In college, though, it's often times the professors who create the problems.
Fair enough. In college, my Calculus II course, taught by a different professor, was terrible. To the credit of the department and administration, they did not keep her around (I forget her formal title, but she was essentially on trial).
I had some good, dedicated and effective high school teachers (although they were perhaps the minority). Unfortunately, as I recall and/or experienced it, the math department was not particularly strong.
