Got an 831.

I had about 8-9 sims, that seemed like a lot, but they really held your hand in the scenarios...if I was in a courtroom I would have to say "Objection, leading the witness."
I am going on to XP or Win 7 OR 70-291. I am worried that 291 with no IT work experience to reference will be too much though. I might be better waiting until I switch to a low level IT job (hopefully in the near future) before I tackle that...what you you all think about that strategy?
