I had Mr. Demek for AP US History in 2003 and he is still, nearly 10 years later, my favorite teacher ever. Not only will he help you significantly with this difficult course, but will teach you life lessons along the way. He structures his classes exactly like a college lecture course, you won't regret him as a teacher! -LC

Demek is one of those teachers who is such an institution at Chantilly I can't imagine going through without having him. He really cares about and respects his students - he puts in SO much work for them and even gives out his home phone number if you have questions. I hate History and Demek made it very near tolerable. If you take the time to do the reading/reviews, you WILL do well on the AP test. Class isn't hard, just very very time-consuming.

Demek was one of the best HS teachers I ever had and truely did prepare me for college. He was a good man, great to talk to, willing to debate the lesson on hand and man...it was just great. If you can, take his class at all costs, you will learn and grow so much as a student and a person I think.
