Do well from here on out. Yeah, it sucks. Yeah, you will replay it in your head 1000 times. Yeah, you will make yourself believe it's unjust and shouldn't have happened. I've done all that. I get it. Don't let it eat away at you though and own you.
Make your resume stand out. Overcome it. I did more to get my job than others did because I had to make up for lost points. Let this failure be an opportunity to force you to become an even better pilot and better applicant than the next guy/gal.
