In what age did students attend the Technical University in St. Petersburg for about 130 years ago? What about other places like the Music Conservatorium or Art Academy there?

What kind of schools did they attend before this or did they just get some education at home? Did probably some monasteries have some part in this at least what concerns boys? A program sent about the monasteries 'Valamo' and 'Konevitsa' in Lago lake told that Valamo was especially connected with the Tsar family and Konevitsa, a minor monastery, was a place where European(?) noble people sent their boys. (See Wikipedia).

What is known about the education of the girls of noble families?
