Priority pass

[geno]

Noob question:

After being notified that the study I signed up for was full, the rep told me I'd get a Priority Pass for next time.

Anyone have experience using one?
After passing screening, will using the pass guarantee me getting in?

it helps a lot. it means you dont have to do that competitive call in thing. i've had 2 but spent them by now.
