What extra curricular activities or things must i do to become a doctor? is volunteering at a hospice good?

Do what you enjoy: Having medically related volunteer activities may help you realize if this is fhe career for you, but they have little "real world" relevance to getting into medical school. A high academic achievement, showing the ability to be committed (to anything- a rock band even) is far more important..

Continue studies!: In addition to volunteering to "buff" your resume, you need a bs degree with a gpa of at least 3.7, all your pre-med requirements completed, good mcat scores, well-received interviews, and letters of recommendation. There are lots of 4.0 gpas, high mcats, and sterling letters of recommendation, so there has to be something that sets you aside from the rest. Sometimes takes 2 or 3 tries to get in.
