This is a "Private Lesson" purchase and not a "Special Grading" purchase.
For a special grading you'll need to purchase that from the "Grading" menu.
Purchase your private lesson here, then contact one of our trainers to organise a time/day. Once that's done the trainer will email admin and admin will confirm with you.
You can purchase multiple private lessons at a time and they will be held as credit until used. Admin will keep a log of credits used and inform you as each session is used.
