Hello there, I've just uploaded my 'magic spreadsheet' which calculates an overall exam % for pupils based on the new GCSE 20/20/30/30 weightings. It's meant to be foolproof but may not be! All feedback welcomed. I've used it to calculate Y11 mock grades and Y10 end-of-year exam grades and it saves a lot of time faffing with calculators. http://www.tes.co.uk/teaching-resource/Excel-spreadsheet-to-calculate-GCSE-overall-score-6092267/ Hope it helps.
