Can someone explain the tie break rule in gymnastics?

Question

First and second got same score in uneven bar final but different medals due to tie break rule. What's the rule? I think the commentators explained but I missed it. I tried google to no avail.

Answer 1

Tie-break rules exist to determine which individual gymnasts or teams advance to the finals in the case of ties for the last qualification place. If ties cannot be broken, larger Final fields are possible. New tie breaking rules have been formulated to reduce the incidence of ties for apparatus medals.

Answer 2

It all depends on the B-score. When two people are tied the one with the highest B-score wins. Every competitor is judged by A-judges and B-judges.

The A-judges "evaluates the content of the exercise on three criteria: the Difficulty Value (DV), Element Group Requirements (EGR) and Connection Value (CV)."

The B-judges "evaluates the performance, ie, the "execution, composition and artistry" of the routine."
