Your tutor is assigned to you at the beginning or your certified course. You should receive an email in the first few days detailing who this is and how to contact them. They will be correcting your workbook and available for free consultations
(30 minutes - Level 1 / 30 minutes x 4 - Level 2).
If you have taken a workshop course your tutor will be the person who ran your workshop.
