Performance Jury

So my music performance jury is coming up this October. I don't know if I'll be ready. I've practiced a lot, but I feel like sometimes I've taken steps backward. Maybe they're just the off days that every musician has now and then and I'm just letting those get me down. But I feel like I should have improved so much more than I have by now. It makes me really sad. I am really worried that I won't pass this jury...
