Amazing person, but cannot teach for her life. I took the course a second time to actually learn the material.

She is chill, but she lacks in the teaching category, which is kind of a downside since she is a teacher. I hope she get's it together because I really do like her. All the best Ms. D. ~!

Ms. D was such a kind teacher! She was always there to talk if I was feeling really down about something, even when I'd long graduated from her science class. Awesome teacher!

Ms. D is really amazing! She's a fabulous teacher - explains things thoroughly, and doesn't mind putting in extra time to help her students... Though half the time, I couldn't understand her notes! XD

Dude she's fun and young but when it comes to explaining math she sucks. Although you can clearly see that she understands what she's saying and talking about.

Since this is her second time teaching a grade 12 math course, I have to admit she's doing a very good job. Her marking is fairly hard, BUT she knows the stuff.

Her math tests are impossible. It is nothing that we've seen before. Students who were getting 90s are now getting 70s, and it affects our future this year.
