Your tutor is assigned to you at the beginning of your certified course. You should receive an email within 7 days detailing who this is and how to contact them. They will be correcting your workbook and will be 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.
