Math was a two-part exam and I once didn't go for the second part. I knew I'd done so badly on the first it was hopeless. I re-took it about four or five times. I think I eventually got it by getting the top GCSE grade.
You have to understand, in this fight, the physical condition and technical preparation are not as important as character and will. The one who's willing to go until the end will win the match.
