She could be an amazing teacher for the best HL students, but she's not great at explaining things fully. Her tests are horrible, but she'll always say that they were easy. Lovely woman, but her skills are better suited to a class that doesn't need a lot of help.
amazing maths teacher, really nice person. she has a gift!
Great teacher and always willing to help those who try. Not being the best at maths myself I would never be afraid to ask her a question. For the first day or two I was a bit wary of her as she comes across a bit strict but she is fair and she is the reason my grades have improved. A Brilliant Woman!
Very strict asdgkjnwbjvbndfjbljkbjlljn l hdgl jklfhg jladehugflugerhlui gluflui hglhljhfljghjhladfhljkhdlfjh
Good teacher,helpful when you didn't understand how to do the math.Good laugh if she liked you and the class wanted to learn instead of sitting there not understanding.
I love Ms. Costello! She's a great maths teacher, and she's really funny. She's strict, and if you don't try she won't like you, but if you do she's lovely!
Nice....but can be intimidating. Treats students unfairly at times but a good maths teacher.
She is definitely the best maths teacher in sac & she can be lovely.I was never scared of her,maybe wary at the start but she's sound out in my opinion!!
i think shes a lovely teacher and is very supportive
ehhhh.,,grand id u dont ask questions and stay quiet at all times!!!!!!!!
not the nicest, but then the school has a policy of holding only one honours class which means that there has to be 30 people in the class, and that can't be easy to teach. but she could defo be nicer
made me cry more than once, have spent a month in the class and considerin leavin the school, being paralysed with fear does not work in a class
lovely teacher as long as you dont ask any questions!!
she is a good teacher as long as you dont get on the wrong side of her
I think she is a brilliant maths teacher and is really nice and funny!I've had her for 3 years and i've no complaints against her!
I think she's lovely and a really good maths teacher.eventhough she is quite sarcastic, I'v had her for 3 years and i thinks she's sound.
very very good if u no wot ur doing and if u dont always ask questions and if u don't understand u should ask r else its ur own fault
Ms. Costello was the best teacher by far when i was in St. Angela's!!!!!!!!
she is a tough teacher but she is really good and gets the work done!!
she a brill teacher and maths is my fav subject and is really nice when your on the right side of her
last comment about the test in 5th yr to kick out anyone who wasn't top of the class wasn't meant for Ms Costello it was Carmel Courtney
A great teacher. She took a real interest in us, and even gave up lunchtimes to take us for extra classes. Just hope there are more Hons Maths classes now...
shes a good teacher but gets a bit sarcastic at times
Very clear and knew that she wasn't infallible.Might want to make tests esp mocks bit easier.i nearly dropped to pass after de pre. got A2 in lc
Great teacher. Very fair and she'll only give out to you if she has a good reason.
Explains things well bt the tests r really hard!! She can luv u r hate u just like that!! but overall excellent teacher!!!
Great teacher but DO NOT get on da wrong side of her or You'll regret it!!!
She is a very good teacher. Best teacher in the school. Very down to earth.
Tough teacher - was terrified of her in the early years but got on great towards the end!
applied maths: the class starts off vhard but by 6th yr you can see she really knows what shes doing. vnice, vhelpful. much more approachable than the subject!
really nice if you try your hardest. excellent teacher.
you knew where you stood with ms.costello. she's very fair. i always appreciated her honesty.
Tough teacher, but excellent. No bull- she'll be nice if she likes you,but she wont pretend otherwise. Dont try to cross her, if you do it'll be your own fault!
