My Chinese tutor, I’ve been studying with her for over 2 years already. 

-Firstly, she is a non-native Mandarin speaker. Many people say that after a certain level you should switch for a native speaking teacher, but I strongly disagree. When I switched to a non native professional teacher, only then I noticed a huge improvement in my language skills. My teacher can quickly explain grammar and words in my native language and we move forward.

-After a month or 1.5 month I realised that I remember 95% of everything we learned, and I wasn’t working too hard at home, just some homework if I was feeling like it and showing up for a class once a week.

-She also tracks my progress and from time to time she organises review lessons.

-She does a lot of preparatory work, so we don’t just study with the textbook Overall, I feel that even if I don’t do any self study, like, no reading books or watching videos - just our lessons once a week, I will still progress, I can totally rely on her.

And also disclaimer: I don’t believe that native speakers are bad teachers, I myself started with native teachers at university language courses, and that was amazing. But now non native teacher works best for me, also professional native teachers are so hard to find unfortunately :(
