What Should I Do To Revise And Prepare For This Assessment?

To prepare for this assessment:

1. Any lessons you missed, ensure you go back to the relevant assignment/lesson on MS Teams and complete the attached student worksheet to check understanding.
2. Use SMART Revise to practice questions – you don’t need to have a task assigned to you to be able to answer questions.
3. Practice writing programs you have already coded in your lesson or didn’t fully complete
4. Use the two GCSE Revision Guides (Theory & Programming) to recap taught knowledge/skills
