Sorry doc, but the typical exam problem was nothing like these problems in either scope or depth. breadth of topics in the book also seemed to wildly exceed those seen or expected on the real exam. If anything, this mostly served to discourage me from studying.
If I get my results back and find that I failed, I will be purchasing a study course to prepare for a retake rather than continuing to use this book for anything but instances where I want to search out a particular problem type.
(3) stars because this presents itself in the title as "CBT questions" which heavily implies it includes problems you should be able to work at a 6 minute pace like the CBT PE exam. These were far too complex and broad to be worked at that pace (for the average idiot like myself).
