Meh debatable. Looking back, medical school was easier in my opinion. While M1/2 was pretty stressful academically, M3 wasn't nearly as bad as it seemed at the time compared to residency. There were literally no expectations of medical students and you were not held accountable for anything and could sit around and read instead of doing things if you really wanted. Meanwhile, as a PGY-2 in IM, you're literally the one who's making the medical decisions outside of rounding hours. Granted you have pharmacy/ability to touch base with consultants/MICU if you really need help, it's a lot of work. Nothing against Psychiatry. It's an important field, but the culture is less detail oriented/laid back and you're never really primary unless you're an intern on General Neurology or something. With IM/Gen Surg, you're watching every lab value that comes out on the patient and making decisions constantly, not to mention the additional burden of the OR as a Surgical Resident. All in all, like others have said, your residency choice has a lot to do with that experience.
