Good day, so in less than a month I'll be graduating from (Highschool? I don't know exactly what to call it since my country's education system is a bit different than other systems - Latvia.) 

And In this highschool you also get a certificate based on which career you choose eg. a Chef or a Computer Technician. 

Starting next semester there is going to be a new study called a "Programmer Technician", which I have been offered to teach, since I've been working as a programmer since I was 15 yo. How would I go on to teaching, like assess the students, give them homework (eg. how much etc.). How prepared should I be when the lesson happens. Stuff like that.

EDIT:
I'm currently 20 years old, and the students will be 16 year olds
