Hello! Welcome to Italki! Did you know that each community tutor and professional teacher on Italki is different? Not every tutor and teacher helps teach kids. Not every tutor and teacher helps with professional business English. Not every tutor and teacher helps with test prep. Not every tutor and teacher helps students at every single language level. Each tutor and teacher you encounter on Italki has a different way of helping and different things they can help with. It's not a one size fits all type of thing. There's so much variety on Italki. The best advice I can give you from being a tutor myself on Italki for 7 years is to read a tutor or teachers profile completely before booking a lesson with them. Learn as much as you can about them before booking their class. Also if you're looking for free language exchange the best way to find that is going to the community section on Italki and looking for other posts that mention free language exchange. If you message a tutor or teacher on Italki chances are they will not help you for free.
