' i am not yelling i am just raising the volume of my voice'
Quite a good teacher although he's prone to sudden fits of rage and yelling for five seconds and then he's calm. Totally unpredictable.
He says "in effect" a lot. Like, a LOT. Also, he loses his mind with rage so often that it's completely ineffective. Cool glasses tho.
Not a very good maths teacher in my opinion. Tends to rely on giving 1 example of a problem and expecting us to know it. Yells and hurls abuse when we don't understand, rather than help us.
