It can be hard to conceptualize just how long the process of becoming a doctor is when you’re 15, 18, or even 24. Becoming a doctor is a long process, with some specialties requiring training up to 11 years, not including your undergraduate degree. After spending four years on your undergraduate degree, you’ll spend four more years in medical school. Then you’ll have three to seven years of residency, and possibly a few more if you plan on specializing with a fellowship.​
