books!!! never used a book for an exam in my life. NJ master/contractor - Philadelphia master/contractor - NJ Inspector/sub code officer HHS/ICS/Plan reviewer in NJ-PA City of Scranton & wilkes-barre master so I have a few Pa class A cities, just questions, I remember talking to tom when he was first building this site 20 yrs ago or so. I remember he had two right answers and I brought it to his attention, nice guy even then to take the time out to chat with me, that was just before I started Statewide electrical inspection. I don't use study guides or books , or tabs for that matter because I think I makes a person dependent on just one way and only one way. open or closed book - I do well. most guys cant learn by themselves so they started these companies to help get you through an exam, the trick with exams is how fast are you at finding a question with the timer ticking in your face. and back then we had to know everything! including tons of theory- resistance, capacitance, they don't do it anymore and I never got soft, I like a challenge. ask yourself what the square root of 3 is without a calculator, if it took longer than a second then your getting soft (1.732) exams are only getting tougher and tougher so it wont hurt to start reading about semi conductors yes electron flow - accepted and conventional accepted is pos to neg where conventional or the truth is it flows from negative to positive, that's why transistors and MOSFETS emitters are all switching negative or zero-vcc
