I regret to inform you that you are misinformed. I have spoken to my school, there are multiple solutions to this problem. First and most obvious is the school is going to contact the universities explaining my plight. Second, my school has the ability to request a deletion of a turnitin submission. This deletion process only exists because in the past, turnitin's record system has made Extended Essays and applications a pain. Furthermore, If a university sees a 100% plagiarism match, that looks very strange given my academic record and where I am applying. They will no doubt look into it. They will trace it back to turnitin. Moreover, if the universities check their database for personal statements in that particular subject there wont be a record of THAT one. Lastly, I have more than enough evidence to prove that this is my own work; emails with questions on little things in my PS, google doc record, academic courses mentioned which I have taken and have records of, books I have read and can prove purchase of long before I wrote the PS. Of course I can also show the submission, the digital receipt and my turnitin account.
