The story behind my topic choice

A wasted time... that is what i consider my school years. The last 8 years of schooling i have had to learn the same things over and over. I now should be in the 12th grade but am not because i have given up on doing the same work over and over. They teach the same things over and over and i know the material so why cant i just test out of the classes? If i could have tested out of my classes i could have graduated already.
