Comments and Concerns from questionnaires
– Public examination: weighting, SRA, duration and question types of written papers
– SBA and investigative study: teachers’ and students’ workload, weighting, class size, fairness, requirements and assessment
– Curriculum content: cater for learner differences, teaching hours, resources
