It'd be an amazing start.
A stupid amount of my wife's medical education was completely wasted for two reasons:
* "To make sure you know what career to go into". No. You don't need 2 years to see every possible option. Everyone has some idea before they even go to med school. Focus on the 2 to 6 that you care about.
* Residency application. 4th year was a complete joke. Most of it was consumed with travel/distractions while applying to residency. Maybe 2 or 3 months of actual learning fit in their.

The med school my wife's residency is associated with is actually a 3 year program. They skip summers and condense a lot of information.
