My mother is a doctor, she leaves home at nine o'clock.​ (Моя мама - врач, она уходит из дома в девять часов.)

Все глаголы стоят во времени Present Simple, так как описаны регулярные действия

Answer 3

In this sentence, it seems like you are describing a future event and a habitual action. Here is the corrected version of the sentence:

"My mother is going to be a doctor, and she leaves home at nine o'clock."

This sentence uses the present tense "is going to be" to indicate a future plan, and the present tense "leaves" to describe a habitual action.
