it is true Mr. Yoder is not mean he is a very nice person. The thing is when the students are jerks of course he will yell any teacher would.
Most teachers teach from the book most probably don't know anything past their teaching subject. But Yoder is genius and goes on about knowledge and goes further than anyone.Knows more than the book.
he teaches a challenging class keep that in mind. I find that if I do all the reading and take notes when I'm suppost to I rarely have trouble. Also he has the most interesting collection of clocks
Has a lot of knowledge, but doesnt convey it well to a class. classes prone to sleep. Has a quirky sense of humore. means well but can be intimidating. does not prepare well for ap exam.
He's an average dude, but he was in the marines which I think is respectable. Just because he sounds boring doesn't mean he's a bad teacher.
