I would love to studying Biology at youruniversity. I have always been good in Sciencesubjects, especially Biology. I am very interestedin the natural world, and love plants and animals.I have a lot of experience with animals as I havemany pets at home, including a dog, a cat, somefish and a terrapin. Since I was sixteen, I haveworked in a Garden Centre at Saturdays and Ihave learned a lot about the conditions plantsneed to grow well in. I enjoy being outdoors andwill really enjoy Biology field trips. I am good at Maths and Chemistry which I think are bothimportant when studying Biology.
