Impress the jury at the academy might still not be enough to get into a conservatory

I had my percussion exam at my academy. As I'm the one with the highest level in the academy, I played last. I tried to be as calm as possible but my knees were shacking when I played the vibraphone and the marimba. I played the six pieces I had played in the class concert few months ago. This time I played them very much better than then. I tried to calm down and I barely made any mistaked. There is something I don't like about the academy's marimba, it has small bars and so I think it's easier to hit the wrong notes. I think the best piece was probably the piece I played on the drums even though at one point I played the wrong thing but I managed not to make it seem like a mistake. There were two headmasters and the teacher giving points of the exam and I scored 94% which is a pretty high mark. The jury was apparently impressed of what I played and susprided of my high level. This was nice to hear but this might still not be enough to get into a conservatory and I'm very stressed about that.

I have my accordion exam in the middle of my exam week and my harpsichord exam in between the written and the oral exams.
