Premedical Gap Years can be a good opportunity to obtain professional medical work experience (for instance, you can work as an EMT, a medical assistant, or a scribe)
Advantage
The Premedical gap year is a good opportunity to rack up on patient exposure hours. Obtaining medical work experience tells the admissions committee that you are committed to medicine. This can actually make you money instead of taking money from your pocket.
Disadvantage
If you go full-time into any of these jobs, you will not have time to study for MCAT or pursue programs that can improve your GPA if your scores are not good enough for the school you like. However, you can improve your GPA or prepare and write the MCAT exam if you are working part-time.
If you do not have enough patient exposure hours, you can go for this option if your MCAT and GPA scores are already okay for the med schools you like. But if you have enough patient exposure hours and your MCAT or GPA score is very low for what your school of choice requires, do not go for this option. Make sure to get DO physician shadowing hours if you want to apply to DO programs
