How do you come, or how do you get to school?

Teaching this sentence structure (and variations of it) to non native (Chinese) speakers, the book I have been given suggests "how do you come to school." Intuitively, I thought this to be wrong; it should be get instead of come.

After some research, it seems come is right only if a conversation is taking place between two people at the place of reference (in this case, school).

However, I think "how do(es) they/he/she get to school" is grammatically correct rather than "how do(es) they /he/she come to school." Therefore the answer would be "he/she/they go(es) by bus/car/bike/", not "he/she/they come(s) by bus/car/bike."

I am aware that go is used when the action is away from the speaker, and come when the action is toward the speaker.

But I am still unsure, thus any suggestions would be appreciated.
