I had Mrs Rhodes back in 1988 for my Senior Calculus class. Very good teacher. She used to race us doing math, we had calcualtors and she used a slide rule (i am not making this up) and she would win. Those who didnt have her as a teacher didnt like her, but she was one of the best.
The toughest teacher I ever had but also probably the best. I'll admit I hated her at first because she pushes you so hard, but I have nothing but the utmost respect for her today.
