Just to clarify by the way, you only get the point if you guess all the judges who did buzz if everyone understands me. You don't get a point per judge correct otherwise you could just predict all 4 for each one and cheat
So for example:
If someone predicted Simon & Amanda would buzz an act yet only Simon did, you would get 0 points.
If someone predicted Simon & Amanda would buzz and Simon, Amanda & David buzzed then you would get 0 points.
I hope that's clear?
