The main similarities and differences:

a - High school subject teacher, Blighty, 6 lesson plans/week. Mark homework, parents' nights, go home after class.
b - China equivalent, 2 LPs/week. Mark homework, attend parents' nights, stay at school after class.
c - FT of English, oral teacher, high school in China, 1/2 LPs/week. No homework, no parents' nights, go home after class.

a, b, c = 24, 20, 16 classes/week respectively.

a & b give and mark exams and class tests. c has no duties regarding tests, exams and assessments. They don't take place for oral English.

Yes, tidily compared, but there's another consideration to fling into the equation and that's if the FT's employer has contracts all over the shop, in which case the poor FT can spend many hours a day traveling between schools...and even taking in a teaching session on the 6th floor of somebody's flat where noisy-out-of-control-kids could be waiting. All of your schools and homes to visit during the day could be far-flung and difficult to find. Have you ever worked for an employer in China like that?

Be glad when Silverboy returns as he seems to offer the sort of topics that, curious, PRC and co want to answer.
