Throwing aside the blithering retard guise for a second, I have a question for all fellow nerds. I'm thinking about getting my A+ Certification just for shits and giggles (and in case my writing career falls through). What does it cost, and is there any reading material you would suggest I read up on? I took some of the practice questions, and the only parts I had any sort of trouble with were networking questions (not my strong suite).
