Not everyone aiming to get into med schools have the work experience to back them up, or at least fatten their resumes. What should you do if you are one of these people?
The simplest thing that you can do if you still have time is to make sure you get some experience! Get experience really quick by volunteering your time and services in local nursing homes, hospitals, or even caring for a loved one. Volunteering in an institution will be plus points since you can also use your “boss” their as a reference. As for caring for friends and family you get to at least mention the fact in interviews. Just make sure you also research on the background of their ailment (Are they recovering from surgery/an accident or do they have chronic illnesses or rare disorders?) so that you can explain and show your knowledge of the medical aspect of the care and also how you know that the care you provided was correct.
If by the time the interview is due and you still have no real work experience, then make sure to be honest and just highlight your other strong points as well as your observations and reflections on what you have seen in hospitals and other health care environments, even if just as a visitor or patient.
