If you are curious about the schedule of a public school teacher in Korea, I’ve shared mine in our most recent video! I’d say that my schedule is very basic and ideal. The classes are in large blocks with 10 minute breaks in between each class. My afternoons are free to plan for the next days classes, and I am able to teach one extra after school class for some extra money. As you can see, I teach each class once a week for 40 minutes. This isn’t ideal, but I work at a big school and there are too many students to teach them twice a week, so this will vary depending on your school.
Your schedule can change by semester or by the year, also depending on your school. My first year at this school I taught only 5th and 6th grade, so obviously I taught them 2-3x a week. Then they decided they wanted me to teach 3rd and 4th grade as well, and my schedule changed to what it is now.
