^ your old Patek Repeater Tourbillion?
I know this post is two years old, but…What part of “Stop. Put your pencils down. Close your book.” did you not understand?
So when they said, “Put your pencils down”, you kept your pencil in your hand. And when they said, “Close your exam booklet”, you kept it open. Then you come on here and ask, “How do I fight it?”
My .02 - you don’t. You throw yourself at the mercy of the court and hope for leniency.
With one minute left in the PM session of any level, you should already be at least 30 minutes into enjoying your post-exam activities.
My Repeater goes off at the end of the exam. Everyone thinks I’m a showoff.
In college, they are really lenient when time is up.

^ good suggestions. I always carry a watch with me, and set it to perfectly measure 3 hours from exam start. I know literally how many seconds i have left,
and I put my pencil down, and close exam book with 10 seconds to go.
i was shocked at the amount of people around me who had no watch.
You’d be more surprised at the amount of people that go in with no prep, especially at L1. They must think it’s a series 7 exam.
