I love Mr. Greenall, he is an amazing teacher, and he loves what he's doing. I can talk to him about anything.
He teaches in a way that makes us able to understand and remember the concepts. He is also very friendly.
Excellent teacher, well set rules and has a good understanding of a student's psyche and how he/she will act. Good sense of humor.
I used to enjoy him, but after he failed me after the exam when i had been passing the whole year, put in so much effort and got nothing out of it, not fair
One of the best teachers I have ever had! Explains things well. Made the exam impossible though.
Mr Greenall is such an awsome science teacher! He makes subjects like chemistry very easy to understand!
