Seth Dixon, Ph.D.‘s insight:

It’s that time of year to really buckle down; several teachers have created PDFs versions of review guides for the AP Human Geography test.  James Nelsen, a veteran APHG teacher has produced a “grand review.”  This resource intentionally does not come with a key to force the students to delve deeper and search for the answers themselves.  Allison Hunt had her students create their own study guide for the APHG test focusing on the ‘big ideas.’  Best of luck and these and other resources are archived on my “thematic” tab on http://geographyeducation.org.
