Band 6 is supposed to be 89+/105 raw (source: advice line & marker at our school)
but of course it depends on the cohort & how hard they judge the exam to be.
But generally 89+ raw = band6 apparently.
then definitely no band 6 for me. depending on how harshly they mark my BNW/BNR and Lear responses... i know i got like 12/20 for Mod C... and for Area of Study.. well i reckon i went well there.... who knows actually.
