How much 'net speaking time' per lesson?

[Torsten]

Let's say you are a student attending an English class. How much 'net speaking time' do you think you get every lesson assuming there are 7 other students in the group.

TOEIC listening, question-response: Do you prefer lobster or crab?

Torsten, I think you mean "net speaking time". We don't use "netto" in English.
