A book that really helped me when I went back to university was

Other than motivation, I attribute the study skills I learned in there to my success. It was well before I ever thought I had ADD.It’s kind of a workbook at the same time, caters to various learning styles and is very visual. Worth every penny!
Now if only I could find it, I would re-read it and force my kids to read it:-) Still haven’t solved the misplaced items problems as you can see
