1 Structure and Timing
- Duration: 120 minutes.
- Questions: Section A (55 marks): three to four free-response questions, all compulsory. Section B (20 marks): two questions, answer one.
- Marks: 75 total across both sections.
- Calculator & data booklet: Allowed; ensure quick navigation for constants and spectroscopy tables.
Pacing rule of thumb: About 1.6 minutes per mark. Allocate time before writing—e.g., a 15-mark free-response question (~24 minutes) or the 20-mark Section B essay (~32 minutes). Reserve 5 minutes at the end for a final proof-read.
