My DC (different schools) are getting one go at a mock and one go at a final assessment per subject and they are being done in strict exam conditions just like the public exams would have been. They are the main basis of the grades alongside a much less significant element of coursework but even that has to have been done in class rather than outside where they may have had help
Opoponax. That is very strict, and actually does fit in with the guidance. We have all noted on here that these are "additional assessment opportunites" and not exams, and that is what they should be. However, you are right, in that different schools are approaching these assessments differently. Certainly, of the schools I know, the NEA's are being taken into consideration for the final grade, and all of the work will have been done at home. How could it have been otherwise? all the students were AT home.
