If anyone manages to ever get through to the qualification page, I was only asked three questions before they decided I wasn't good enough for them...
1) M or F
2) Ages of kids
I'm assuming they don't care what sex you are. I was honest about the other two and told them I had no kids under 18 and that I preferred not to answer about my income. You might want to think about picking answers sort of in the middle and see if they like that any better.
