I think that under normal circumstances the only way to become a chunin would be to go through the chunin exam. However, the exam was a total mess and now the Leaf village is in crisis. I think they will do a batch of field promotions, like in the military. The new Hokage or the group that is temporarily running things will just say, "OK, right now what we need is more high-level ninjas. You, you, and you: you are all now officially chunins." In that case Sakura would be a good choice.

I do agree that she failed her test though. In that case a tie in a fight meant a failure. If a tie was a pass she would have been allowed to go on.
in that case, yeah i agree that the new hokage would do that. but i doubt he/she will choose sakura. although she has been in A ranked missions, but she didn't do much in them...
