I will edit:
*school papers (I do not endorse cheating, and will not write a paper for you.)
I am a native English (USA, although I am familiar with differences in UK spelling and grammar and can do so by request.) I scored in the 99th percentile on reading comprehension SATs, and have consistently high marks on written work.
I'm perfectly happy to work on the same piece again for an additional five dollars, as well as a longer piece.
I have also assisted in critiquing creative works, and I'd be happy to give general advice on storytelling, character development, word choice, etc.
