I appeared twice in ISSB tests after completing my F.Sc.
I was recommended the second time but I could not clear final medical due to minor knee knock problem.
In my second attempt I completed all the obstacles except zig-zag.
Long jump is 8 feet. It is the most easiest obstacle.
One needs to be super fit to clear all 9 obstacles in 2 minutes. Build your Stamina. A person who has strong muscles despite his light weight(about 60kg) has a lot of advantage. But the main assessment in obstacles is of courage, determination and tact, apart from fitness level.
