Don't do the Hogan prep. Seriously, you don't need to. Interview prep and app review is worthwhile but Hogan prep isn't. Follow the advice earlier in this thread and you'll be fine. I did no prep and passed. I heard I actually got a smiley face on the test as well, but I can't confirm that... Seriously, just don't overthink it. I know it's easier said than done, but I think I'm not alone in that view.
