The same answer, judged the way your scheme says.

Short questions earn one mark per creditworthy point, with alternatives and "do not accept" rules. Longer ones are judged as a whole against level descriptors. Switch to see one answer under each.

Q4 Explain why heating increases the rate. [6] · PointsStudent A

When you heat it the particles get more energy

and move faster. They

collide more often so it

reacts quicker.

4/6Good. Now explain activation energy.

Chapter 3 · Your anchors

Your blind marks become the standard.

At least two independent AI markers mark every answer. You mark a short sample with their marks hidden. Your marks confirm those answers, and they become anchors that settle the uncertain ones.

You blind-mark a short sample. Your marks become anchors that settle the uncertain answers.

3/6Proposed mark. Student C makes the same three points as the Student H anchor. "Hit each other more" is credited the way you credited collisions. You still approve it in review.

Two AI markers mark each answer independently. Six agree, so those marks stand. Four disagree, so they are uncertain.

Good: you linked heat to energy and faster particles. Next, explain why more collisions make it faster: more of them have enough energy to react.

How does Mark My Tests check its marks?

At least two independent AI markers draft a mark for every answer against your mark scheme. You blind-mark a small sample without seeing the AI’s marks; those answers become anchors for settling uncertain or disputed answers. Anything still uncertain is flagged for you, and you approve every mark before it is released.

Why mark a sample blind?

If you could see the AI’s mark first, it would be hard not to be influenced by it. Marking blind gives an independent reference for how you apply the scheme.

How big is the sample?

Small: enough to anchor close calls, without redoing the marking yourself.

Is the AI ever the only marker?

No. A teacher approves every mark before results are released.

Start with this week's test.

Use the paper you already set. You stay in control of every mark, your students get better feedback, and you see what to teach next.
