Hi. If you take your exam in Downer's Grove,Illinois, do you know if it is accepted in all other surrounding towns? Would it be accepted in Cook county as well as DuPage or Will county? Or is there a limited area that it is accepted? Can you get your license in Downer's Grove and then go pull a permit or do a job in say...Burr Ridge, LaGrange, Burbank, Oak Forest, Tinley Park, Orland Park, etc. Are there other testing sites in this area? Do you know how many questions are on the exam and the approximate cost of the test? Is there a site I could go to that could tell me? I have an out of state friend who is moving here in April and would like to take the electrician's exam mainly for residential, not commercial...do they seperate the 2 or is it all one test? Do I ask too many questions? Probably...sorry, but I don't have a clue about this stuff. Thanks, Nancy
