Bill was my Science teacher in 10th Grade, back in 1981. he was an awesome teacher and I always enjoyed his class!
Mr. Pinkston is a great teacher. He knows what he's doing...after all, he's been teaching Biology for 41 years. He does have a temper, but I've only seen him use it when people were being stupid.
He was very hard, but he brings the best out in a persons work if they are willing to try.
he wasnt a horrible teacher but goodness what a bad temper sometimes. "Laugh in chapter 24 and you are out"
This one's got a nasty temper but it's cool to watch his face turn colors.
