  • OCR A Level Chemistry B (Salters) is infamous for its demanding time pressure, especially on H433/01 (Fundamentals of Chemistry). With 110 marks distributed across 135 minutes, you have roughly 1.2 minutes per mark. However, top scorers do not treat all marks equally. The thirty multiple-choice questions in Section A represent 30 marks, and examiners repeatedly note that candidates who fall behind schedule here struggle to finish the high-yield structured questions in Section B.
