Took his class 25 years ago (class of '80). It was great. Fond memories of him deriving e=mc^2 and asking tough questions like "reduce the ohm to basic units".
Fitz is completey AWESOME! His AP class is hard, though, but I guess it is supposed to be.
Mr. Fitz is my favortie teacher ever! I wish he wasn't retiring though...
Fitz teaches a hard but fair class, and most importantly promotes THINKING in the classroom and not just mindless worksheets!
