I have a ton of certifications, so many that I have more letters AFTER my name than IN my name. That doesn't mean a great deal in a forum setting, but I assure you I worked quite hard to get each of them, and have repeatedly proven so to my peers and clients. A+ isn't one of them. A+ means so little that someone's lack of an A+ means nothing. Many of the best computer/network technicians I've come in contact with have no certifications at all. If I hadn't wanted to be a trainer, I don't know that I would have undergone the effort to get mine, either. The only value A+ has is for people who are switching careers that want to get their foot in the door someplace. Once you've gotten a job that provides the sort of experience A+ tests for, the certification is useless.
But the guys at Best Buy won't fix it anyway, A+ certified or not. They'll send it to Arima.
