The answer is NOT in the book!!!! I found this out the hard way in college as some profs allowed us to use our books during engineering exams which only help if you know how to do the problem solving. I never took the Professional Engineering (PE) exam but you can bring any books you like!!
Now as a prof, I allow open book/notes and design exams to inspire critical thinking and metacognition (awareness and understanding of one’s own thought processes). Samples will be posted after Monday’s final exam.
