Neue Blickwinkel, 2nd Edition, appears to be intended for AP prep use. The content in the book alone is good if only used as a reading resource. I did not have a physical copy to review so this is based on the online content. The online content is neither very interactive nor very intuitive. The online book is a vertical scroll (PDF) style setup. There are only a few interactive links on the book for assignments, that may or may not be self-graded and they require 4 different clicks to begin the assignment. This is very unnecessary and inefficient. If this were just a textbook and reading resource for AP prep, this might be an acceptable resource. As an online resource, it would not be an efficient resource. A teacher could put together his/her own AP resources for a little bit more work than what this resource would require of the teachers who use it.
