I've been having a frustrating experience on my quest with the Top Tier. You can retake it unlimited times on write.com. If it's half decent they give you the e-commerce equal which isn't too bad. My mTurk equal for Top Tier was denied after 2 weeks. I've been calling Crowdsource to see what's up with my re-submission and it sounds like they are just swamped right now. Thanks for those tips and I hope I could help as well. They are super picky.
