Audio Study Guide for AP US History

Question from my niece: My kid HATES reading. Even the Princeton review and Barrons are too much. I am planning to get the flash cards. Is there any point to getting the Amsco now? Kid tends to get confused on multiple choice questions, DBQ seems under control.

My main question is we will be stuck in the car for 10 hours visiting relatives over break. Is there something I can download or order that we can listen to? I know Audible has a Great Courses US History but it is 80 hours long! Any other suggestions? Shorter course? I do not mind paying as long as it is not a fortune. Thank you. Sort of desperate for help!
