As my role is KS5 coordinator my head of department referred me to this article by @billyads_47. This got me thinking to my own experience at A-level and University talking about "marks in the bag" how many "spare marks" have I got to "add" to future modules. By breaking it down to a unit by unit basis I could see exactly what I needed to do in each exam to achieve my target grade. At university I was aiming for a 2:1 but going in to my final year I was on a 2:2. I sat down and worked out what I needed in each future exam, whether or not a resit would be beneficial or a distraction, and what steps could I put in place for me to get that 2:1 I really wanted!!
I have put together a simple spreadsheet which can be found here. The first tab you can input students names and the marks they have achieved in their AS exams. By having a conversation with each student you can agree what is their "Magic Number" for each module. Any work handed below this standard must be resubmitted. The second tab creates print outs for each student so they can stick it on the front of their folders as a constant reminder. The third tab is where you can alter the grade boundaries if needed.
Obviously you want your students to get every mark possible but breaking it down to manageable pieces can make their target/desired grade that bit more manageable. Oh, and my university average.... 60.08% which was 2:1 with a comfortable 0.08% to spare!!
