Hello Juan! "Each user has three trial lessons that they can use to try out italki. You can use 1 trial lesson per teacher, and you can use them whenever you’d like." Choose a teacher of the language you'd like to learn, go to his/ her teacher's page, hit the "book a trial lesson" button and schedule a class. Don't forget to be on time for your class

Hi, these are the instructions from italki. First, press the Find a Teacher button on the top right to access our Teacher Search page. On the Teacher Search, you can customize your search using a number of filters such as where they are from, price, specialities, and more. Check out the teacher’s introduction video to see if they fit your style, and see if their availability matches the time you have. Once you have decided upon a teacher, press the “Book Now” button. You will be prompted to select the type of lesson you want to schedule, the lesson duration (if applicable) and an available time slot. Make sure you select the communication tool that you wish to use, and then confirm your lesson! I hope this helps. Happy learning! :)
