Exam Command Words
| Command word | What the examiner expects |
|---|---|
| Calculate | Work out a numerical answer showing formula, substitution, and units — method marks are only awarded when working is visible |
| Draw the mechanism | Show curly arrows starting from bonds or lone pairs, with intermediates and correct charges |
| Explain | Give chemical reasons for an observation, linking to bonding, structure, or energetic principles |
| Identify | Name or give the formula of a substance, functional group, or spectroscopic feature |
| Outline | Describe the main steps of a process briefly — include essential detail but not full mechanistic drawings |
| Justify | Support a conclusion with specific chemical evidence or reasoning |
Typical Grade Boundaries
| Grade | Approximate mark needed |
|---|---|
| A | 63–73% |
| B | 52–62% |
| C | 42–51% |
| D | 32–41% |
| E | 22–31% |
⚠️ AS Chemistry uses 160 raw marks (80 per paper). Grade thresholds are typically lower than AS Mathematics, reflecting the conceptual difficulty of the subject.
