Analysis has been done into the pass rates of SQA exams, looking at the total cohort of S4 pupils and Nat 5s, rather than just the ones entered in the exams.
Only 40% of S4 kids passed Nat 5 maths. 25% have a pass in biology which they say is the most popular science. What a fucking shambles - no wonder they want to scrap Nat 5s, they can then pretend that everyone's a winner and give all S4s an "achievement certificate" irrespective of whether or not they would know a fraction if it came up and slapped them.
