the best advice I could give anyone taking the exam is ........ 1. completely study & understand all of the electrical FE exam questions from FERM
2. get offical NCEES sample exam and solve every problem in the boook
3. re-word all of the questions in the sample exam & solve.
for example, if the sample exam gives voltage & wants to know the current, make up a similar question and let the given be current & solve for voltage. This is a simplied example but you get the idea. the questions on the exam are the same as the sample exam, but always ask for what was given on the sample. Just know how to solve all of the problems with any givens. solve the questions for delta & wye connections if taking power, etc.
good luck, its not that hard
