The course is delivered online. Typically, the lessons are 2 hours long and 2-3 times a week. The live sessions are taking place twice per week in the evening (Eastern European Time).
Also, the mentors are available based on their timezone and availability but the Education team (Instructors) are available from 15.00 to 23:00 (Greece time) if you need additional live interaction. Apart from that, you can always use the Discord Ticket tool at any time and someone will reach out to you asap.
