I will make another suggestion however, we recently did a review of a product called the LiveScribe Pulse pen (available here: http://www.technoesq.com/law-office-use/2009/02...). This product was designed for students and will record audio and your sons handwritten notes at the same time, allowing for syncronized playback of the two. So if the teacher/professor was speaking about the War of 1812 and your son wrote “The War of 1812″ on the notepad, when he later touched the pen to the words “The War of 1812″ the audio would begin to play of the professor's lecture at that point. This is a tremendous help to any student and particularly one with the issues you are describing as he would only need to write down the key words the professor is talking about to have an “outline” of his lecture. He could then go back and hear exactly what was said for each topic of that outline. I can tell you that I would have gotten at least 1 to 2 grades higher in any class I used this for when I was in High School, College and Law School. Check out the video we made on our post I mentioned above demonstrating how it works for a better understanding.

Good luck and I hope this helps.
