So I submitted my application to Cornell and i realized after the fact that my first sentence of my essay had a noticable grammatical error. The message still gets across well but I failed to acknowledge parallel structure and missed a comma. this was my only real error in the essay. Are colleges really anal about this type of stuff? Like is it enough to make or break an applicant?
You should be okay
This question has been asked and answered literally hundreds of times here. If colleges auto-rejected all applicants with typos, they would likely be unable to fill the class. Chill.
