On italki, people can talk or chat with others for free. This means that some teachers may talk with students for free. Other teachers charge money for helping students, who are learning a language. Edson.all, if you walk English help from a teacher on italki, always ask first if this teacher's help is free or if there is a cost (money to be paid). If you have to pay a teacher on italki, then you must use "ITC" (italki credits)...italki's money or currency. One $1.00 (USD) = 10 ITC (italki credits). For example, your italki teacher spends one hour helping you. Now you must pay the teacher for his or her help and the charge or cost is $20.00. This is what you do when you go to a money exchange in a foreign country. For example, if you come to the USA, you must change your Brazilian reals (BRL) into US dollars (USD), so that you can spend money in the USA. On italki, now you must use either a credit card, a debit card, PayPal, or AliPay to "buy" 200 ITC to pay for the teacher's help. The teacher then knows how to get your money from italki. You are now done paying your teacher. You just follow the instructions on the link under "My Finance" and "Payment". Before you can "buy" ITCs, you must sign-up with correct information like your name, address, how you will pay (credit or debit card, PayPal, AliPay) and so on.

And if you want to find a professional teacher to start structured learning, you will need to use ITC to book for the teacher's session or request his tutoring service. (You can also negotiate a price that both sides are willing to accept.) 10 ITC equal to 1 USD.

The rate of tutor is lower.
