Re: I couldn't remember the answers to the questions
Yeah, if you don't get into one of these jobs pretty much straight out of college, you're screwed on answering the questions. If you do, you just keep a copy of your last form to update them.
Although I will say that when I had to reconstruct some of those questions for some job interviews, the internet was scary good at digging up the answers for me. I could actually reconstruct my housing record all the way back through college.
