swimming as a disabled person

(question for uk members mostly) does any one ever remember swimming in school and working your way up through the A.S.A/ESSA swimming badges my question is what was the furthest badge you managed to get before leaving school

my furthest badge as being a disabled swimmer was 800 meters

Well I don't know how much my experience will be helpful to the above topic but I want to share my experience. I had a stroke about 10 years ago. Before my stroke I knew swimming but after stroke I found that I could just float in pool. I lost all my balance needed for swimming. Luckily I had friends to save me after I started to drown lol. Thanks
