Man, I have no idea why she's a math sub. We had her 3 times this year for Math 12 and all she did was copy notes exactly from the testbook. Then, she taught us by reading right off the notes!
Most students disrespect her from the begining so that's unfair. She's too controlling as she demands complete silence at all times. Treats secondary students like its preschool.
Mean and very unclear with lessons. Quite nice if you give her respect and if your a good student. Just be quiet and do the work, then you'll live and survive out of her class.
