My worry is that they will leave it to the individual schools to arrange and that it will not be fair, transparent or equal.
For example, mocks have been taken at different times and in different formats, some online, some with only a few modules, some being told what would be covered.
Some schools seem very honest and some seem to stretch things a bit more- although I base this mainly on what I have heard from friends different experiences last year and also anecdotal evidence from my teacher friends.
