Might have put wrong high school dates on TAG agreement

I just submitted my TAG agreement to UCSB today. Since I have been out of high school for a few years now it was very difficult getting ahold of my dates of attendance for high schools. To make a long story short, I put I attended high school #1 from 8/2008-8/2009 and high school #2 from 9/2009-6/2012. I can’t remember but I may have been out of school for a few months and not started high school #2 until 2/2010 and had a gap of a few months, but I’m not positive. I have requested transcripts from both high schools but it could take up to a week. Am I in trouble if the dates end up being a few months off? I really don’t want to be denied admission over something as simple as this. Any help is greatly appreciated. Thank you.
