After graduating, you need to go to medical school for four years. While you may have the opportunity to take some classes that will help with your specialization (pediatrics) — most of the classes will be the same that any medical student will take.

After getting your MD, you will spend a minimum of three years as an intern and resident in your field of specialization. Then you take the board exam to be certified in your field.

There are some schools that allow you to get your BS and MD in seven years rather than eight — but there are no shortcuts other than that.

The link below tells you what classes you have to take to get into medical school.
