Hello from the editorial department at Cheng & Tsui! We're developing more resources to help students study for the AP® Japanese Language and Culture exam! You can download some of the study materials for free; we've got a list of all the kanji required for the exam, and a brand-new flashcard program to help study kanji. It covers kanji from every lesson of the Adventures in Japanese series, as well as all the kanji required for the AP* exam, organized by lesson. This could also be a good resource for studying for the JLPT exam or any other Japanese exam. You can download the kanji list and flashcard program here: http://www.cheng-tsui.com/resource_center/adventures_japanese_companion_site
