Key examiner messages
Top priorities from the principal examiner before you revise
The 2023 Foundation papers (1F and 2F) are rated as highly accessible, aligning comfortably with prior sittings.
Paper 1F leaned heavily on direct recall of atomic structures, chemical bonds, and basic extraction methods.
Paper 2F had an outstandingly clear layout, focusing on hydrocarbons, rates, and analysis.
In both papers, early sub-questions utilized multiple-choice or direct matching grids, allowing students to build immediate confidence.

Command word playbook
How to match each command word to the expected response style
Show formula, substitution, and unit; method marks need visible working.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
State features in sequence or list observable properties — do not explain causes unless asked.
Match the expected response style for “Determine” questions.
Match the expected response style for “Plan” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.

Examiner notes & key calculations
- Uncertainty & Error Identification: In Paper 1 Question 10, many candidates struggled to explain the inclusion of the ±0.3 ∘C\pm 0.3\,^{\circ}\text{C}±0.3∘C uncertainty or incorrectly labeled random errors as systematic.
- Maths Conversions: In Paper 1 Question 2.7, many failed to convert 25.0 cm325.0\,\text{cm}^325.0cm3 to dm3\text{dm}^3dm3 when calculating the mass of sodium hydroxide.
- Anomalous Result Calculations: In Paper 2 Question 8.2, a common mistake was including the anomalous Trial 3 when calculating the mean reaction rate and subsequent mean time.
- Squeaky Pop Test Confusion: Students frequently confused a "lit/burning splint" (correct) with a "glowing splint" (which is for oxygen) when describing the test for hydrogen.
