here in south africa medical school is 6years. first year is biophysics, biochemistry, biology, psychology and POME. second year is anatomy and physiology and POME II, third year is anatomical pathology, pharmacology medical psychology,microbiology, and POMEIII. fouth year is forensic medicine, community health, chemical pathology, clinical pharmacology and POMEIV(clinical rotations included). 5th and 6th is clinical rotations only. as you can see from the list, everything gets closer and closer to clinical medicine as you go higher so its a culture that everyone gets to mock at his juniors that they are not actually studying medicine. the pattern continues until fourth year. then you get to be mocked about how you are just decorating in the ward without doing anything worthy and your head is "hyperressonant on perccussion"
my point is, people will always have a go at their juniors. it will never stop.
