Here are my answers:
1 - How may hours you work (in the school)per month?
about 8 hours a day, 5 days a week, 4 weeks a month
total: 160 per month (but that's what I get paid for - teachers always put in more time than what's on their paycheck! haha.)
2 - How many classes do you teach?
I teach 6 classes + 1 duty (study hall)
3 - How many grades do you teach?
I teach only 6th grade.
4 - What is your monthly wage? What is the minimum wage in your country?
I get paid about $57,000 per year, so about $4750 a month. I've been teaching for 8 years, though, so I guess starting teachers would be getting about $2800 per month.
5 - What is your level of satisfaction as a teacher (1 to 5, being 5 a complete satisfaction)?
I love teaching. It's true that some days are better than others, and some classes are better than others.
Overall, though, I would say I'm completely satisfied - 5.
