Hi I am in the same position as you, feeling very unsure about the new marking scheme. I suppose confidence will grow as we get through the first cohort. The best we can do, like you say, is mark to the scheme as accurately as we can and trust that it will be reflected in the grades. The issue is that as teachers we are expected to feed back to SLT etc with grades - and this year it is all very up in the air. I do feel more anxious than usual this time round! Where did you read that 45 would be C? We were told by AQA that grade boundaries wouldn't be set until during the summer, so as far as I am aware its still all undecided. When we did the marking task I'm sure the tolerance level was 6 marks either side, do you think this will be the same for our marking this year? Surely AQA want the new syllabus to be a success, so I can't see them making them making the grade boundaries too high? Completely understand where you are coming from with this one, I'm sure lots of people do!
