I went from mid 500s to ~700 in four months, so I know it can be done. I didn't have as many baddies, but I didn't have anything positive either. Can you get on as an AU on a couple of accts with long, good history--parents maybe? I got on a couple of my MIL's accts as an AU and my scores jumped a bunch. I've read lots of posts from people that got med collections deleted using Whychat's method. I had good luck getting rid of my unpaid medical collection by offering PFD (pay for deletion).
