UCUNTS

Got 55 minuts to send off my ucas thingy to my tutot (i say 55 mins but they probably wanted me to send it off by the end of uni rather than now but i didnt ask if that was the case so didnt know). Its fucking long....what the hell do i put in my personal statement? Is it was to just apply for courses anywhere not knowing what the place is like? DOes it matter if i put wrong exam boards into the boxes as i dont have my gcse results anymore?
