hazard perception (driving theory)

Has anyone done their theory uk...
How many times on one clip can you click?
I know you can't click in a pattern but how many clicks can you actually do.
Obviously not through out the clip.
Reason I'm asking is becaus I have my test next week and I've been doing the hazards on an app.. and I think mostly everything is a hazard but only one develops so I click about 7 times.. 😬😬😬😬
