Two time Failure

I really just feel so stupid. I went to a class that I done last year and still failed the course.I tell you this I thought I nailed that test but when they called me out I was like dawn either I passed or I didn't. But after seeing other people come outside too I knew that I was part of the failing group and again would be sent home with a bad taste in my mouth. God I hate that feeling I never ever have failed anything in the Military before until now. I just knew I passed but found out today I have to go back again for the third time next Feb, God everyone wish me luck cause I'm going to need it. I hope that three times the charm you know what I mean.
