She is absolutely the WORST teacher in history!! She is unorganized and loses students work ALL THE TIME, then gives the students 0's. She grades based on how well she likes you and hardly grades things a month after being turned in. She picks favorites, helps them, and makes everybody else's lives horrible.

If you respect her, she'll respect you. When most students approach her, demanding a better grade with an angry attitude, of course she'll get mad. However, if you approach her kindly, she will actually give you opportunities to improve your grade or better understand the material. Her biggest flaw is probably being disorganized and an extremely limited understanding of technology. Overall, she's a pretty good teacher, though she can be outright terrible some days. Talk w/her AFTER school,kindly

I had Mrs.Mahon for a chemistry class and it was my worst experience with a teacher. She is unfair to students, she gives tests that have different material than what she taught in class, and she takes for ever to grade just about any assignment she gave you so your grade online could be an A but then at the end of the semester you get a C without even knowing you were having problems. All around just bad

I'm not from Damien but have her for summer school Chemistry. I wish she taught at my school because she really knows how to make science interesting. I'd love to take her for AP Biology too. She has a good sense of humor and makes learning fun.

Absolutely useless teacher for AP Chemistry. She has not gotten out of her seat a single day to teach any material in the span of the whole second semester (with the exception of the day that teacher evaluation were being done, of course) She never updates grades and never passes back graded work. That way you won't know your grade until the day you receive your report card. As an Honors Chemistry and AP Biology teacher, she is respectable, but I highly recommend avoiding her AP Chemistry class.
