I made this index for quick reference on during the exam (for the 2010/2011/2012 NCEES electrical), based on keywords. A lot of the problems seem to cover multiple topics (i.e. per unit and transformers). Hope this helps, I'd be curious to see if you come up with a correlation to the specific topics.
