First time using!

hi all! My s/o is using QF for the first time next week for a pre-employment test and physical and our nerves are pretty high lol. I just have a few questions!

1. Has anyone used QF at a hospital/occupational health facility that has on site lab testing? What was your experience?

   1. Is there a difference between the 6.3 and 6.4? I’ve read almost every post about QuickFix on this app and can’t really find anything.

Thanks in advance and wish us luck next week!
