Final answer:
The names of the five textbooks Agatha was given in 'The School for Good and Evil' are not provided in the reference text, so I cannot supply them accurately.
Step-by-step explanation:
The question pertains to the fantasy novel The School for Good and Evil, but the actual names of the five textbooks Agatha was given at the School for Good are not provided in the text that you referenced.
Typically, information like this would be found directly in the novel's text or supplemental materials related to the series.
As I do not have the precise books mentioned from the novel in your provided reference, I am unable to provide the names of Agatha's textbooks.
