The last place you should ever find Ms Blackney is in a classroom teaching the youthful yearning minds of Holliston high school students. Her altogether loathsome personality considered alongside her complete lack of any relevant leadership or inspirational ability qualify her as without exception the worst instructor I've ever had the displeasure of being forced to see every day. This teacher is unceasing in her contribution to mounting disengagement of public school students everywhere.

She looks and acts like a walking corpse. She has no emotions or a sense of humor. I fell asleep almost every day. Awful, awful, awful.

Oh man, well, she's very nice and a very good teacher, most of the time. Her classes can drag on because they can get boring but you will survive if you have it during the lunch period. Sometimes her grading system does not make sense but she gives extra credit so it all evens out. Just make sure you always do your homework (or fake doing it) because she checks it everyday =(.

Ms. Blackney is a good teacher, but when it comes to fairness, she is on the judgemental side. She is not very leinant with work or tests, and has a high expectations, so take advantage of her extra help, it will also show her that you are trying to learn the material which will help when it comes down to participation grades

I heart Mrs. Blackney. People give her a hard time but she's sooo nice. She's always willing to help out. Just keep up with your work and try to have a good attitude and you'll do well in her class.

So boring that it hurts. I fell asleep every single day in her class. But she's willing to give extra help, which is what helped me get a good grade. But honestly, the unbearable outfits are distracting.

She's sooooooooooo easy. It's very entertaining to make fun of her voice during class. She sounds like a little boy goin through puberty.

I thought she taught the material very well, and if you show respect, and a good attitude, you will do well in the class.

Mrs. Blackney always offered extra help, and never moved on unless we understood the material. Her class was fine if you had a good attitude. I got an A+
