I spent alot of time writing mine before I started college. When I started my main tutor said it wasn't right at all and advised me to start again. However I was sure I had it right and was the best it could be so I took it to another tutor and she said it was fantastic. We did change a few words and reorganise a little but she talked me through it and explained why she thought it needed doing. It all made sense in the end.

If you think its right then stick with it I did and I got in. Its called a personal statement for a reason!
