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

UnitTitleAssessmentWeight of A level2027 date
AS 1Basic Concepts in Physical and Inorganic ChemistryWritten, 1h 30m: 10 multiple-choice marks and 80 structured marks16%Tue 11 May, morning
AS 2Further Physical and Inorganic Chemistry and an Introduction to Organic ChemistryWritten, 1h 30m: 10 multiple-choice marks and 80 structured marks16%Tue 18 May, morning
AS 3Basic Practical ChemistryBooklet 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 1Further Physical and Organic ChemistryWritten, 2 hours: 10 multiple-choice marks and 100 structured marks24%Fri 28 May, morning
A2 2Analytical, Transition Metals, Electrochemistry and Organic Nitrogen ChemistryWritten, 2 hours: 10 multiple-choice marks and 100 structured marks24%Wed 9 June, morning
A2 3Further Practical ChemistryBooklet 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:

q=mc\Delta T=50\times4.18\times6.5=1358.5\ \text{J}
\Delta H=-\frac{1358.5}{0.025\times1000}=-54.3\ \text{kJ mol}^{-1}

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.

Common questions

What is the CCEA A-level Chemistry code?
The subject code is 1110. It was first taught in September 2016.
How many exams are in CCEA A-level Chemistry?
Eight papers on the 2027 timetable: four theory papers and the laboratory and written booklets for each practical unit.
When are the CCEA A-level Chemistry exams in 2027?
From Friday 30 April (AS 3 practical) to Wednesday 16 June (A2 3 theory).
How is CCEA A-level Chemistry graded?
A* to E, with an A* needing an A overall and 90% of the A2 uniform marks.
Is there a data sheet?
Yes. CCEA provides a data sheet with the Periodic Table. See our guide to it.
