Billie, babysitter - GU22 Woking

My name is Billie , I'm 15 years old, will be 16 at the start of 2015. I'm a very bright year 11 student from Woking High School, meaning I can help your children out with their homework if needed, especially with Maths, Science and English. I speak fluent English; growing up here in England and speaking the language my whole life.
I have experience with children as my brother is 12 who I have been looking after and helping my mother out most of his life, and my sisters; 3, 5, 8 which I have been looking after for a couple of years when I visit (as I don't live with them). Living in Goldsworth Park, it shouldn't be too much of a problem travelling as long as it's not too far. I am willing to help out very much. Hope to hear from one of you lovely families very soon!
