Wrong dates in Personal Statement

<p>Hey guys, I talked about an event that happened that negatively affected my GPA and mixed the dates. I wrote about an event that happened in Spring of 2013, but in my essay I wrote Spring of 2012 like an idiot. Don't know how I overlooked it. I'm worried the UC's will read it and look at my grades for 2012 and see all A's and be like ***. Is this a big deal or no?</p>
