Present tenses

Hello, I'm having doubts about the use of the present continuous in these sentences. Could you check if they are correct? Thank you.

All the sentences are from an assignment comparing university students and high schoolers, and should talk about generalizations. Personally, I would keep the forms in # 2 and 3. As for #1, I'd change 'are living into 'live'. While the continuous form would be appropriate for university students to show the action is temporary, I feel like this wouldn't be correct to express the permanent state of living with one's parents.

1) Being a high school pupil and a university student are experiences that differ in three main aspects, such as whom you are living with, what you are studying, and who guides you in life.
2) University students are studying simply because they wanted to.
3) During the university period, students are living with their friends or flatmates even far away from homes and do not come back there so often.
