This is what a comrade answered in your questions(in greek)
here
Translation(as better i can)
1. The nature of (high school)students occupations its merely a protest about the murdering of the kid. (University) students occupations have a most advanced agenda (state repression, education matter, political claims etc).
2. At occupations its mainly decided the course of mobilizations , the coordination with other political spaces and different local actions.
3.There are a lot opinions on what should happened or what will happen. Thats who's sure ,today, its the politicization of a big part of the youth and the solidarity of a big part of the greek society too.
4. General political education inside working class in the way marxists want ,dont exists, if anyone excludes την constantly presence of kke in some labour spaces. This, of course, doesnt mean that there isnt relative political conversations between workers. It just develops spontaneously and not in the frames some "campaign" :-ρ
5. No
Obviously this are my opinions and if the comrade wants to learn more tell him to take a look at the english section of indymedia.

As i said that was a translation of what a comrade said in the athensindymedia, there arent my answers!
