" To tie a knot seems to be a simple thing, and yet there  are right ways and wrong ways of doing it, and scouts ought to know the right way."
Baden-Powell, Scouting for Boys, 1915

Three Tests of a Good Knot:

It should be easy to tie
It should stay tied       
    It should be easy to untie

In Scouting you will need to learn knots for your advancements through the ranks. You shouldn't only learn these knots for advancements but keep the knowledge you have learned for later on in life. Its better to know a knot and not need it, than need a knot and not know it.
