What WJEC AS Chemistry covers, and what it leaves out

WJEC AS Chemistry is the first year of the 1410QS course and a qualification in its own right, examined in 2 units, AS Unit 1 and AS Unit 2. This page holds only what the AS examines: 19 topics across 148 subtopics, 2,335 active recall questions, starting with Formulae and Equations, Basic Ideas About Atoms and Chemical Calculations. The 17 topics kept back for the second year are not shown, so nothing here is content you have not been taught yet.

Starting the second year? The full WJEC A-Level Chemistry page adds the A2 topics on top of everything here.

How do the names of ions formed from non-metal elements differ from the names of the elements themselves?

Key term

Why can iron form more than one ion, and how is this shown in a compound's name?

Spaced Repetition Schedule

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.

Chemistry revision questions

Common questions about revising WJEC AS-Level Chemistry. Tap any to open it.

What is on WJEC AS Chemistry?

19 topics across 148 subtopics, examined in AS Unit 1 and AS Unit 2. They are all listed on this page, and each one opens to the subtopics inside it. The full topic list is Formulae and Equations, Basic Ideas About Atoms, Chemical Calculations, Bonding, Solid Structures, The Periodic Table and more.

Does AS Chemistry count towards the full A level?

Yes. In Wales the AS units are marked as a standalone AS qualification and also carry forward into the full WJEC A level, which is why the first year matters more here than it does in England. Check the current weighting on the 1410QS specification, as it is set by the board rather than by us.

What is the difference between AS and A level Chemistry?

AS is the first-year units only. The A level adds 17 further topics, among them Redox and Standard Electrode Potential, Redox Reactions, Chemistry of the P-Block, 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.

When do you sit WJEC AS Chemistry?

Normally at the end of Year 12, in the summer series. That gives you one year to memorise 2,335 questions' worth of material, which is roughly 12 questions a day across an academic year if you start in September.

How should you revise for AS Chemistry?

By retrieval, not rereading. Cover the answer, pull it from memory, then check. Levo runs that loop across all 19 AS topics and brings each question back on a spaced schedule, so what you learn in September is still there in June.

Is it worth revising AS content again for the A level?

Yes, and it is the mistake most students make. The second-year papers assume the first year, and in Wales 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.

How many questions are there for WJEC AS Chemistry?

2,335, written from the 1410QS subject content and grouped into 148 subtopics so you can work one small area at a time rather than a whole topic at once.

Can you use Levo for just the AS year?

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.

Every question in Chemistry, on a schedule.

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.
