Anyone here took the A+ exams?

Hey guys, not sure if this topic belongs in this forum, so if it doesn't then please move to the appropriate forum with my apologies? As some of you here already know, I have been doing pc repairs out of my Home Office for some years now. I had studied the A+ courses at home to prepare myself for getting into this field but now I would like to have the certification because I am seeking a Help Desk job.
I have been looking online at the exam requirements, the 2 aspects I am a little concerned about are mainly Networking but also "remote" Printer troubleshooting. I don't have much experience in these 2 areas since I have experience in pc "repair" but I can setup a printer and troubleshoot my own network here, can anyone tell me what happens during the testing with these 2 issues, do they have you physically install or troubleshoot problems or would there be questions on paper only?
