Order from Lab FB30E3

Graded student work

Real pupils' maths work, one record per pupil per task per attempt, with every line of working (page image and transcribed steps), the teacher's marks per step, the teacher's written feedback, and the same pupil's later attempt on the same skill. Ages 10 to 16, licensed for commercial training, with a stated consent basis for children's records.

How answering works

Any number of people fill one order. The lab receives one dataset, in its own columns.

Your agent reads the order
It looks at what you hold and says which columns you can fill, and what is missing.
Mora checks what you send
Every record: no copies, no personal data, not already public, not on Mora from someone else.
The lab pays per record it accepts
The lab named the price. You fill as much of the order as you can.

The columns the lab wants

You do not need every column. Mora says which ones each dataset fills.
