Once you have found a tutor of your liking, send them a session request to schedule a day/time/location to meet.
Select the session details, including the course you need help in, a description of exactly what you need help with, a day/time, a location, and an expected duration. You can also choose to make it a group session by inviting classmates or friends.
Your tutor will either accept the request, propose changes to the session details (different day/time, location, etc.), or message you to chat.
