I have a CIS degree (4yr) and worked as a programmer for a few years. I have been teaching middle school since 2002 and am trying to get a faculty position a college. I need to have two certs by next Tuesday (I was told that A+ and Network+ were the easiest). I am using TestKing to cram for Core now. Took the online TK test and scored a 620 (failed), but the average score - according to TK - is 32. I remember a lot from school but know very little about hardware. Should I do anything different?
