She is a very nice person and is very dedicated to teaching. She makes tons of study guides and tries her best to help you do well, but she is not the best at explaining things.

Ms. Costello is a great person, but not the #1 teacher. In class, she might not be able to help you 100%, but if you go to extra help, she is very clear and takes her time with you, one-on-one. If you

you basically have to learn algebra 2 by yourself; whenever you ask her how to solve something or clarify something she'll explain so that you would only understand it if you weren't having problems):

i thought she was a great teacher, she actually showed us where all these random equations came from (derived them), which no teacher had ever done, yet to me is so important to understand the topic

She is absolutely the worst teacher I've ever had. You might as well just stay home and ask a tutor to teach you. Advice for future students: Bail out ASAP!!!

This woman should be a kindergarten teacher. She could care less what you do as long as you get good grades. An A for playing on my calculator? Yes please.

I had her in her first year of teaching. She was unable to conrtol the class, and over half the class had to see other math tutors in order to pass. Dumb!!!

Ms Costello is a great teacher, but a little bit too easy. Being in her class reminds me of pre-school.
