There are several things they can fail you at on the Medical class 1, that you can do something about without doing surgery.
I failed because of a issue regarding my eyes, and have fixed this trough hard traning and I have been on several vision tests since and I am now withing thoose limits needed.
It will be easier for me to go to another country because where I live, they won`t let me take a retest for some reason..
