What grade does he deserve?

Tricks can sometimes take forever and seem impossible to land. For Christian Flores it was a laser flip down a triple set. It took him 20+ missions over 2 years to finally roll away from it. Christian recounts what it physically and mentally took for him to land the hardest trick he has ever done.

When someone tries but fails, over and over and over and over . . .  and over and over and over again, then gets it.  What is their grade? 

Their report card grade?

Their semester grade? 

Their finals test grade? 

Would you fail him? Would you hold him back? 

Is he a failure?
