The Gudaos were still high school students when the Grand Order began, and we know how stressful the Japanese education is. So, Dr Romani needs to ensure their education went on that once humanity is saved, they can go back to high school/college.

So, with lots of Servants available, there has to be some qualified to give lessions though may not be teacher materials. Let’s brainstorm together :D

Literature & Language: Japanese - Murasaki Shikibu, English - Shakespear, Anderson, French - Queen Marie (?)

Maths: Leonidas

History: Now this is complicated, since many Servants came with lore that’s different from the school textbooks XDDDD If the Gudaos write King Arthur and Nero are women in exams, they certainly will get a F.

Music, Home Economics, Arts and Physical Education: we have more than enough Servants for these subjects

Sex Education: (cough cough) I think many Servants are more than happy to give it to the Masters (cough cough)

Physics: Tesla, Edison

Chemistry: Paracelsus Von Hohenheim, Avicebron

Biology: Asclepius with Jack and Nightingale as helpers
