CCEA AS-Level Chemistry 1110
CCEA AS Chemistry is the first year of the 1110 course and a qualification in its own right, examined in 2 units, Unit AS 1 and Unit AS 2. This page holds only what the AS examines: 20 topics across 120 subtopics, 1,686 active recall questions, starting with Formulae, Equations and Amounts of Substance, Atomic Structure and Bonding. The 16 topics kept back for the second year are not shown, so nothing here is content you have not been taught yet.

How reviews are timed
Levo will automatically distribute all of your progress into a spaced repetition calendar. Once you’ve answered, it’s scheduled for you on the next day in the spaced repetition schedule. Over time, the gaps between your recall get bigger, from a day to three years, reinforcing memorisation over a long period of time.

Common questions about revising CCEA AS-Level Chemistry. Tap any to open it.
20 topics across 120 subtopics, examined in Unit AS 1 and Unit AS 2. They are all listed on this page, and each one opens to the subtopics inside it. The full topic list is Formulae, Equations and Amounts of Substance, Atomic Structure, Bonding, Intermolecular Forces and Structure, Shapes of Molecules and Ions, Redox and more.
Yes. In Northern Ireland the AS units are marked as a standalone AS qualification and also carry forward into the full CCEA A level, which is why the first year matters more here than it does in England. Check the current weighting on the 1110 specification, as it is set by the board rather than by us.
AS is the first-year units only. The A level adds 16 further topics, among them Lattice Enthalpy, Entropy and Free Energy, Rates of Reaction, Equilibrium and Acid-Base Equilibria, and expects you to connect them back to the AS material. Work the AS content here, then move up to the full A level page when you start the second year.
Normally at the end of Year 12, in the summer series. That gives you one year to memorise 1,686 questions' worth of material, which is roughly 9 questions a day across an academic year if you start in September.
By retrieval, not rereading. Cover the answer, pull it from memory, then check. Levo runs that loop across all 20 AS topics and brings each question back on a spaced schedule, so what you learn in September is still there in June.
Yes, and it is the mistake most students make. The second-year papers assume the first year, and in Northern Ireland the AS marks usually count towards the final grade as well. Keeping the AS material on a spaced schedule through Year 13 costs far less time than relearning it.
1,686, written from the 1110 subject content and grouped into 120 subtopics so you can work one small area at a time rather than a whole topic at once.
Yes. Pick your subject, choose the AS topics on the topic screen, and every mode — the 3-step method, Cram, Blank Blitz, Build It and Test It — works only that material. Add the second-year topics when you get to them.
Attempt a question from memory, write the correct version, then attempt it again. Levo records the jump between your first attempt and your last, and brings each question back on the day you are due to forget it.
