Periods of roman education and their characteristics?

The Romans had three periods of education. The Primary school where the student learned the basics of reading, writing and arithmetic. The Secondary schools were mostly literary in nature, where the student learned about the famous Greek and Roman writers, learned history and geography and became fluent in Greek and Latin. The Post-Secondary school, which could be loosly compared to our colleges or "finishing schools" was where the student received more lessons in literature, public speaking, speech composition and politics. The Primary and Secondary periods of schooling could be learned at home if the family were wealth enough, but the Post-Secondary was almost always caried out in Greece.
