I was reapplying the same institution that rejected me last year. Last year, I didn't reach any potential supervisors and this year, one professor told me that he would assist me. I thought the personal statement last year was not the main problem for rejection so I reused it. I added two lines to update my background information. And I reworded two paragraphs though they express the same meaning and intention.
I just realized this problem after I submitting my application. Will the selection committee check my previous application? Will it pose negative effect? I really don't want to mess it up with this opportunity.
