Does she want to learn to speak french, read french literature, learn french history?
Has she taken any steps or done any preparation or is she starting from dot?
The reason I ask is because students usually switch minors.
I would recommend that if she really wants to learn french she takes it as a summer class.
She wants French language, not history or literature. That’s the main reason she dropped it as a major and selected it as a minor. She is currently in French V in High School.
