What did Cleopatra study or practice when she was young?

Your question can only be answered by guesswork because we have absolutely no information about Cleopatra's childhood or youth. She makes her first appearance in history as a grown woman of 22 when she meets Caesar although there is reference to her as being queen with her brother a few years before. We could guess that she studied politics and foreign affairs as proved in her later life. She was fluent in languages, although the languages that she is reported to have spoken were mostly dialects of Egyptian. She obviously would have had to practice her reading and writing as all children did.
