He is by far the best teacher i have ever had. He can see when you are confused about something and will ask you what you are confused about. and the same worksheets from 1970 got me a 5 on the ap
I had Mr. Shaffer for Algebra II and AP Calc...the only 2 years I learned mathematics in High School. Fantastic teacher and asset to the department!
Great teacher...if you're in AP, be ready to get wrecked for awhile- he prepares you for the exam only if you do the work. Favors guys/athletes/whizzes/siblings of former students...adorable overall.
He's a great teacher. He knows what he's doing and you will pass the class, if you do the work. He's harsh, but you learn.
The only thing Shaffer cares about is the AP exam and he makes sure that he weeds out any students that are not certain 5s.
This man is the best teacher Ive ever had, plain and simple. Classes were good I learned something new every day and he helped Tong become a great teacher too!
best math teacher in the state proven by the AP scores and an all around awesome guy
i hate math but loved his class..had him back in 1991....thanks for the help
Shaffer is the man. He knows Math better than anyone else and loves to teach it. He is an EXCELLENT teacher.
dispite your best efforts, i 5'd the ap. let's hear him say the greek alphabet(er)
Shaff loves math more than life itself. He tries to be funny, but everyone laughs just because when he laughs he like snorts and drools all over the place
Anyone who gives him a 1 in helpfulness or clarity needs to go to Integrated Math, where you spend the entire year learning how to count to 10.
Very good teacher, but don't expect it to be easy. You'll learn a ton, but only if you cooperate. Other teachers may be easier, but you won't learn as much.
When talking about parabablers and theters and comers he is very helpful
Great man! Easy to talk with, cares about kids. He knows his stuff, and has helped me raise my grade a ton. Hats off to Shaffer! (JR)
He has gotten 127 5's since he started teaching, Im pretty sure I got one. The man knows what he is doing
Great teacher, he has all of his extra quizzes, but they are great, it makes you learn the stuff, the best math teacher at the school
mr. shaffer is one of the best teachers i've ever had. a really great person and teacher.
he knows exactly what he's teaching at all times, he knows math front and back. he's only hard because people can't keep up with him.
he'll make you work and long, but he almost guarantees a 5 on the AP test for all his students. that cannot be said about any other AP teacher.
He's a hard teacher but thats whats good about him...he challenges our minds and he knows when to help out. He's a really good teacher and i want to say thanks
Shaffer is hard, but cool. he knows what kids have a hard time with.
