This sounds great and will really enhance your application. Just remember to say what skills these experiences have given you, what you have learnt from them and how these things will help you at university and as a doctor. I would also recommend including something about any clinical skills or procedures that you may have observed, and also include a paragraph about your current academic studies, such as what subjects you have enjoyed most and why, and how your experience at college has prepared you for studying at degree level. Good luck!
I have just sent off my application for adult nursing and have given you the advice that I was given when writing my personal statement. I have also done work experience in a hospice, and was given a fantastic opportunity to shadow different teams within the hospice. So writing about the hospice would be valuable to your personal statement, and would really impress the admissions tutors. They always look for people who stand out, and not many people have the opportunity to volunteer or do work experience in a hospice.
