Most post-baccalaureate programs require personal statements, and sometimes, shorter essays. The post-baccalaureate personal statement is similar to the medical school personal statement, but it requires a different approach as your objective is to be accepted into a post-baccalaureate program and not medical school.
Your post-baccalaureate personal statement should discuss your desirable qualities and significant, relevant experiences in medicine. The main difference between this and the medical school personal statement is that your path to medical school is not straightforward.
