Not a particularly helpful or sociable guy, at least in AP, but he definitely teaches what you need to know. If you've come from Mr. Taylor and expect to have a teacher that really connects to you, you're in for disappointment, but for academics he's fine. I wish he would try to connect with students or work to improve their comprehension, but I suppose he's teaching to a schedule.

One of the best teachers at the school (in my opinion). He knows history and government very well and is always willing to help. Compared to most classes, he gives a lot of homework in AP Us History, though very little in AP US Gov. The tests for APUSH are challenging, though if you just read the textbook, you should have no problems; the tests for AP Gov are not as difficult.

I was in Mr. Blenner's class and T.A.'ed for him. Overall, I felt he was one of the best teachers I've had yet. His tests were easy if you paid attention, took notes, and did what you were supposed to do in class. He made assignments and such more bearable and interesting. A very good teacher, I'd say.

he doesn't like to be questioned and his homework is assigned on random days, makes it hard to remember when its due. Ends up cramming and not discussing everything. Still fun and fairly easy going.

He's a little insecure, so don't challenge him on anything. Essentially a good teacher, get's the info out, but not without loads of long digressions. He's willing to help you though, which is good.

Blenner, Blendogg, Blendizzle, whatever he calls himself...is not the best teacher i've had because he doesn't even look at the students when he lectures. He also flings his hands in the air when he lectures, which gets really annoying.
