Question special

A recent study in the Journal of GME, "Fourth-Year Medical School Course Load and Success as a Medical Intern" showed that the number of rigorous rotations in the fourth year of medical school directly correlated to performance during intern year ( Furthermore, the greater the number of rigorous courses, the stronger the benefit. However, the common wisdom tends to be that fourth year should be relaxing and a time to recharge before residency starts. One common argument for this is to prevent burnout heading into residency. As a counterpoint, if a student is more prepared for residency, they may experience less stress overall. How should one approach the balance between rigorous rotations, less rigorous rotations, research, other extracurriculars, and time off during fourth year?
