I passed my test a year ago and made 86 on my first try. I didnt study much but I will say this. As previous others have posted, do the easy ones first and flag the ones that give you trouble and come back to thim. Ive spent 10 years designing systems under a master and that seemed to have helped me. I suggest a good calculation course like the one Mike Holt sells, and a good NEC course as well.
