I know this is an old thread but I thought I'd reply anyway for anyone currently searching. I've worked at the Coding Network as a private contractor for 2 years now and love it. I also didn't pass the test the first time and the reasoning given to me for no feedback for your wrong answers is that they give everyone the same test so it would jeopardize the integrity of the test of they gave out the answers, they offered me a free 8 hour course done by their E&M director after which I passed the next test. I referred a few people who have more experience than me and had trouble passing so I guess that part is frustrating but once I got past the employment process I've been happy ever since. I tell them how much I want to work and as long as I meet my weekly quotas I completely make my own schedule which is really fantastic with young kids and a husband that works a retail schedule. I've worked under 3 supervisors so far, one which I did not like and two that I love so I guess like any job it depends how you get along with your boss but so far everyone has seemed so family friendly and understanding of being a private contractor and not having an exact schedule. I always try and make myself a little more available around month end but it's not required. They have tons of different accounts so I'm sure experiences vary but I work for a hospital for a few different specialties doing E&M and I love it 100000000x more than working in an office
