CCEA A-level Chemistry: the specification
CCEA first taught GCE Chemistry in September 2016, with AS awards from 2017 and A level awards from 2018. The AS is 40% of the A level. Each practical unit has two booklets, one done in the laboratory and one sat in an exam hall, and the practical units are early in the exam calendar.
CCEA A-level Chemistry units
| Unit | Title | Assessment | Weight of A level | 2027 date |
|---|---|---|---|---|
| AS 1 | Basic Concepts in Physical and Inorganic Chemistry | Written, 1h 30m: 10 multiple-choice marks and 80 structured marks | 16% | Tue 11 May, morning |
| AS 2 | Further Physical and Inorganic Chemistry and an Introduction to Organic Chemistry | Written, 1h 30m: 10 multiple-choice marks and 80 structured marks | 16% | Tue 18 May, morning |
| AS 3 | Basic Practical Chemistry | Booklet A in the laboratory (25 marks, 1h 15m) and Booklet B in an exam hall (55 marks, 1h 15m) | 8% | Fri 30 Apr (practical), Thu 27 May (theory) |
| A2 1 | Further Physical and Organic Chemistry | Written, 2 hours: 10 multiple-choice marks and 100 structured marks | 24% | Fri 28 May, morning |
| A2 2 | Analytical, Transition Metals, Electrochemistry and Organic Nitrogen Chemistry | Written, 2 hours: 10 multiple-choice marks and 100 structured marks | 24% | Wed 9 June, morning |
| A2 3 | Further Practical Chemistry | Booklet A in the laboratory (30 marks, 1h 15m) and Booklet B in an exam hall (60 marks, 1h 15m) | 12% | Thu 6 May (practical), Wed 16 June (theory) |
The early start matters: both laboratory papers fall before the first theory paper, on 30 April and 6 May, so practical skills need to be secure by the end of April. CCEA morning papers normally start at 9.15am. Dates are from CCEA's final GCE timetable; see the CCEA A-level timetable 2027. A data sheet is provided; see our CCEA A-level Chemistry data sheet guide.
Worked example in CCEA Chemistry style
Enthalpy from calorimetry. A reaction warms 50 g of water by 6.5 K, and 0.025 mol of reactant was used. Use 4.18 J g⁻¹ K⁻¹ for the specific heat capacity of the water:
The temperature rose, so the reaction is exothermic and ΔH is negative. Give the answer to 3 significant figures, −54.3 kJ mol⁻¹.
CCEA A-level Chemistry grades
CCEA adds uniform marks from all six chemistry units. At A level the grades are A* to E and the A* demands an A overall plus at least 90% of the A2 maximum. Do not confuse this with the CCEA GCSE scale, which includes C*; there is no C* at A level. A-level grades explained gives the context.
Use the daily papers as short timed mocks for CCEA A-level Chemistry
Practise on A-level Chemistry Year 1 and Year 2. A daily paper is 8 questions and 25 to 35 marks, not a CCEA paper, and has no multiple-choice section.
- What it covers well: amount of substance, enthalpy and Hess's law, equilibria, redox, kinetics, organic chemistry, buffers, electrode potentials, transition metals and spectroscopy.
- What it does not cover: the practical units AS 3 and A2 3, which are 20% of the A level between them, and the 10-mark multiple-choice sections.
Time one daily paper, then add the 10-mark multiple-choice section from a CCEA past paper so you get used to answering it quickly.
Exam answers
Uni-Sine does not publish official answers, past paper answers or board mark schemes. Answers and a worked mark scheme come with today's paper once you have marked it, line by line.
Common mistakes in CCEA A-level Chemistry
- Neglecting the practical units. They are 20% of the A level.
- Getting the sign of ΔH wrong. Temperature rising means exothermic and a negative ΔH.
- Forgetting the multiple-choice section. It is 10 marks of every theory paper.
- Not reading the data sheet. Look up constants before you start.
