Philosophy Lessons

[PhilGR]

Next year in highschool he have a philiosophy course , so which of the teachings of actualized.org could help me to understand the lesson and project my own ideas clearly? We are going to have Plato and greek philosophers thoughts (we will scratch the surface),but  not non-duality and deconstruction(although I can make a topic about this) as it is really deep for the average student.
