Dermatology Residency inquiry

I know derma is a very competitive field. Hirap makapasok sa residency.

But can I ask anyone who might know, paano po ang duty sched ng Derma resi? Since, I think, wala namang Emergency/ER cases ang derma, may pre-duty-from pa din po ba?

Also, does anyone know other hospitals that offer one na hindi sana nasa metro manila? Preferrably in South Luzon. Saw na meron na sa DLSUMC, but hindi daw PDS-accredited? How does that work?

Thank you
