Look, you get another chance at the tests, you seem to know what your weakness was so stop licking your wounds, find a way to improve it and give it your best shot.
If you do this and fail, you can hold your head up high, if you don't have a go you will always wonder "what if ?"
There will always be other options if it doesn't work out, so go and show them what you can do, they are looking for people who are low training risk, that means they bounce back when things are tough.
One life, give it your best.
