I got failed in my test.

As I stated in the last note, I took an exam for the teacher recruitment. But unfortunately, I got failed.
The first part of the exam that was by done on paper and pencil and I was did pretty good. My scores is were up by 4 points higher compared to the cutoff line. However in the second part, round, I got 4 points lower than scores compared to the average scores points that of the other test takers my competitors got. In the a teaching demonstration part, I thought I did was pretty good, but to the eyes of the testers supervisors, I was just a novice who cannot control his own lesson. In the an interview part, I mumbled, which I think lead to led to me having pretty low scores in this part too.
Hopefully, I could improve my English skills in this year and pass the exam...
