That brings me back! When I was a kid I did mostly good in school, but I despised history, so my mom would take the manual and make small test like question and quizzes that I could then consult the manual for to answer (but not copy). Just the change of format made it a search information task instead of reading a huge dull bunch of text.

History was always my weakest subject, but the help my mom gave always kept me from having terrible grades
