Attached are the learning objectives for the A2 ICT theory exam (IT3).
There could be questions about anything listed here, so it is a good idea to read through and pick out the bits you are not so hot on.
Create a revision poster on one or more of the unit topics (for example a poster all about topic 4, working with ICT). Try to strike a balance between enough information to be worthwhile, but not so much that it would be overwhelming to read.
Once completed, you could share your posters with the rest of the group so that you have a full set to go on your bedroom wall!
