Page "Medical school" Paragraph 65

Doctors wanting to pursue a speciality must take entrance exams at the public / private institution of their choice that offers them.

Again, it is with less difficulty that doctors can enter a residency at a private teaching hospital than at a state-funded one, for the above stated reason.

Speciality courses endure for about two to five years, depending on the branch of medicine the physician has chosen.

There is no legal limit for the number of specialities a doctor can learn, although most doctors choose to do one and then they sub-specialise for further job opportunities and less overall competition, along with higher wages.
