"Water is the element of change. Similar to their element, waterbenders are extremely adaptable and versatile. Waterbending concentrates on the flow of energy and focuses less on strength and more on turning the opponent's own energy against them. While a bender's victory in battle depends on their skill or ingenuity, waterbenders, unlike other benders, gain a serious advantage or disadvantage depending on the amount of water around them, although highly skilled waterbenders can draw water from anywhere; they can draw humidity from the air and bend the water in living things, especially plants. As the element of change, waterbenders can fluidly and quickly alternate from defense to offense, from a wall of ice to a jet of water, turning their opponent's strength against them. The sub-skills for waterbending are healing, bloodbending, and spiritbending."

As a waterbender, you are adaptable, ever changing, and internally balanced. You find little to no trouble acclimating to new situations, understanding emotions, and just going with it. Waterbenders practice Tai Chi Chuan Yang Style, so maybe you should try that out if you're interested.

Does this not feel right?
Remember, you know yourself better than any person or test. This test would likely tell Korra she's a firebender, but she knows her connection to water regardless.
But maybe we're on the right track.
Do you feel closer to air? Perhaps you're a cloud or mist bender and you could learn a mix of Tai Chi and Ba Gua Zhang.
Feel closer to earth? Perhaps you're a lavabender, in which case you could learn Baji Quan. Or maybe you're a plantbender, which could be the Wing Chun style.
Drawn to fire? You could scald your opponents with steam with a bit of influence from Northern Shaolin Kung Fu, or on the other end of the spectrum you could bend lightning almost exclusively.
Only you can decide that.
