I have been trying to find this out too. All I have been able to find is a post saying that schools all do different things, which does not seem like a level playing field to me. Those who warn the children they have a minute left give the children th
E opportunity to go through and mark off any multiple choice questions that they have missed. We live in county but my Dd is attending an out of county school so will prob be taking her test at one of the grammars, I assume they are more likely to stick to the rules whatever they are.
I think the posts you have found are for the old test.
The new test is administered by a CD. No interaction with a human once the test has started.
