How old do you think I am in terms of writing?

1-5 years old:

Mary sue characters; with little to no understanding of how cruel the world is and writes with no knowledge of he/she's writing about. Grammar is really off.  Doesn't know how to spell at all.

6-10 years old:

Knows at least a bit of what he/she's writing about; really basic grammar. Cliche plot. More or less have spelling mistakes on each chapter.

11-13 years old:

Characters and plot are okay. Nothing 'wow' but has that little uniqueness to it. If I was your English teacher, I would give you an A or B on your grammar. Baby vocabulary words.

14-19 years old:

Characters and plot are original. Barely no grammar mistakes at all. Good use of voice and vocabulary words are of a honor student. 

years old:

Characters and plot are absolutely amazing and original; even if it's cliche, the writing style makes up for it. Very good use of voice; top notch vocabulary. You know what you're writing about and your knowledge about the world and it's cruelty is no more than ABC to you. 

My Original Age: 13 years old
