CCEA AS-Level Software Systems Development CL4
CCEA AS Software Systems Development is the first year of the CL4 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: 9 topics across 100 subtopics, 1,381 active recall questions, starting with Software and the Development Environment, Defining Data: Types, Variables and Classes and Program Control Structures. The 9 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.

Six ways to work the same material
Common questions about revising CCEA AS-Level Software Systems Development. Tap any to open it.
9 topics across 100 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 Software and the Development Environment, Defining Data: Types, Variables and Classes, Program Control Structures, Objects, Classes and Data Structures, Exception Handling and Managing Input and Output, Testing an Object Oriented Application 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 CL4 specification, as it is set by the board rather than by us.
AS is the first-year units only. The A level adds 9 further topics, among them Reasons for Systems Development and Systems Methodologies, Managing Projects, Testing Strategies, 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 1,381 questions' worth of material, which is roughly 7 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 9 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.
1,381, written from the CL4 subject content and grouped into 100 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.
