Making corrections to PhD application after submitting it I am currently finishing up my applications for PhD programs (in the humanities) and, in working on a draft of my statement of purpose for one school that I have not yet turned in, I noticed an error. It is a typo of sorts, the omission of a verb which renders a sentence "nonsensical." The intention of the sentence is still clear but it is quite noticeable. Think something along the lines of "Excited by the interdisciplinary dialogue at Harvard." as the uncorrected sentence, missing an "I am" at the beginning. 

The problem is, I have already submitted this mistake in my statement of purpose for four or five other schools. A friend, who submitted corrections to his applications when he was applying, says that it would be no problem to contact the department/admissions administrative secretary with a corrected PDF. I am afraid of making it worse by submitting corrections, but also would love to fix it if I could. 

Any thoughts on what I should do? I am kicking myself for not noticing it... what's really annoying, is that I noticed and fixed it in two applications, but must have reverted to a previous draft for the rest of the schools. 

All advice/reassurance/chastisement is appreciated, especially if you have experience with such a blunder yourself.
This is not a material error. I wouldn't worry about it. We get much more egregious errors such as uploading the wrong statement (such as for another school) or misspelling the name of the core faculty member you wanted to work with, etc. 

You'd think those types of mistakes would be killer, but they really aren't. We realize students are under stress and that application management systems are cumbersome. We're all human in the end.

What's most important is the qualifications of the applicant as a whole.
