Hi, be aware that many blogs pre-date the new application process that began in 2012, I believe. Now, you get medically pre-cleared (meaning they flag and screen for major and/or obvious problems), but the full medical stuff doesn't come until after your invitation. It also all comes electronically. You'll get an email as soon as you accept your invitation directing you to go to the MAP and see your tasks. Right away you'll see vaccination and dental stuff. If you got invited less than 6 months before staging all the other stuff will be there too - if your invitation comes early, all of that will arrive 180 days before staging. It varies depending on your age and gender, and while it's a lot, it's not unmanageable. Good luck.
