Better Grades through Martial Arts

Is it true that martial arts students make better grades?  

Why does this happen? 

Because true martial arts develop individual character. Its not something that happens directly, character development is a bi-product of all the hard work and effort a student puts in to improve their skills. It's a bi-product of learning new material both mentally and physically which in turn add to the individuals character. Collectively the martial arts contribute to building the individuals character.

Here is a fact - it doesn't happen over night. Just as it takes consistent learning, consistent practice, consistent training to earn the next martial arts belt level making good grades and improving a individuals mind takes consistent learning, consistent practice and consistent training. The discipline brought on by the martial arts to accomplish this also becomes the character building discipline in making better grades in young students.
