Thank you Stephen for your diagnostics. Let's assume the passing score is 56/80 (70%), then you are only off the cut by 13.
My analysis of your diagnostics is based on this one overall concept, the areas that you received low marks might indicate that you need more work on the fundamentals, concepts and skills. The areas where you were slightly below average indicates that you need more practice problems.
I think the biggest impact that you can make on your studying would be in the Circuits area (Circuit analysis and Devices & Power Electronic Circuits). This accounts for 12 missed problems. The best sources that explain Devices & Power Electronic Circuits that I have come across are Electrical Machines, Drives and Power Systems by Wildi (which you already have) and Electric Machinery Fundamentals by Chapman. The Chapman book gives a very good introduction to Power Electronics (rectifers, VFDs, RMS, thyristors, diodes, etc).
Codes and Standards: Did you try the CI Code Problems? There are a lot of problems that basically take you through the entire NEC.
Rotating Machines: If you can understand the equivalent circuits for motors and generators, then you should be in a good spot. If you need more problems, then Wildi and Chapman are a good place to start.
Special Applications: This one is tough, there are so many topics and it is difficult to understand all of them. I can send you some information on this topic in a PM.
Protection: Another tough one. I have associates that work for the utility company and that is all they focus on...just Protection. This area also used Symmetrical Components, Per Unit and CTs, VTs. IEEE Recommended Practice for Protection and Coordination or Industrial and Commercial Power Systems helped me gain more understanding in this field. It is just a very long and difficult read. Other people prefer the Art and Science of Protective Relaying by GE.
