Great teacher, makes everything you do in his class count, so he keeps you on your toes and you always know where you stand with your grades. Just read the assigned pages and you'll be fine.

talks too much about his personal stories and not enough about what we should be learning. when you have a test, you basically have to memorize every hand out you have (even if you haven't talked about it in class).

he is the best teacher ever. it is very sad that he is going to retire. i feel that i have learned a lot from him so far this year. in the beginning of the year, he was a bit scary with his sense of humor and all, but after you get to know him, its funny. What he tells us about his lives is interesting--it is nice to know something about your teachers besides what he is like in your classroom. His tests are hard-you have to make sure that you study. But they are usually only worth 5 or 10 points=good.

One of my all-time favorites. True, he had people he liked more than others, but these are the people who make an effort. He's also nice outside of class.

Mr. Ahearn is a great person but if you slack off in his class your grade will suffer. If you do all of your work and study you'll get a good grade.
