I have a college degree and am a teacher. You will not go wrong hiring me. I'll have this done quickly and without any errors. I am a native speaker of English.
I have been professionally trained by the grammar professor at my former college. The training included how to properly grade a test essay, meaning I am aware of what is generally looked for in an excellent essay.
I am an online tutor in English as my part time job. I know basic rules of English grammar which I've learned from school and from the reference materials I have.
