such a nice man but can be hard to understand sometimes. Gives really good notes.
Left Mtsackville in 1996, have very fond memories of Mr. o'S. Not only a great teacher but a pure gentleman too.
He is THE nicest teacher the school..always there to help...such a gentleman! I loved maths because of him...hes an absolute genius!!
Mr O'Sullivan is the nicest and cutest man ever!He's a brill maths teacher,the school will be lost without him!I actually enjoy maths because of him!Thank you!!
The nicest man ever. He lived for his students. I was the worst honours maths student ever but he kept pushing me & I got thru it. Brought us on best tour ever!
although this teacher is very popular, his teaching ability is extremely poor and his communication skills are equally bad. just being honest.
Fantastic teacher, I'd have had no hope passing honours LC without him. Excellent for applied maths too. Not too strict but has no problem controlling a class
He is the most adorable man! you just have to love him! he was a brill Maths and Applied Maths teacher not to mention principal!! seriously brilliant! Thank you
LEGEND! think all the young male teachers should try to be more like you!
Brill maths teacher. Helps everyone and you can't mess in class cos hes too nice and he always has a joke.
Best maths teacher-essential 2 d school!Sooo helpful and brill teacher. Such a dote also
Mr O'Sullivan is such a nice person and teacher but his writing is hard to understand.
he is so kind-hearted, adored by all his students and even by those students he doesn't teach! He's a brilliant maths teacher and was a brilliant vice-principal
