So Let's say we show up to fbi academy but fail the physical fitness test as soon as we get there will we be kicked out or what will happen

Typically you need to pass a physical fitness test before being accepted.

Probably recruiter can answer this better, but i believe you would be given a second chance to fix the issue

Prepare like an Olympic Champion contender- failure is not an option, spirit to win and excell will take you anywhere!

Okay I have awhile before I can apply but I like being prepared thanks
