can you share your experience of learning English on Italki from a professional teacher?

Hello everyone. I'm here to get some experiences about learning from a teacher on Italki. I have purchused purchased a trial lesson. It's the first time I will have an online class. How can I make the best most of my class? How does your teacher conduct your class? I don't want to be aimless and planless, so I would really appreciate it if you can could share with me with your (own) experience(s). Thank you!
