For the uneducated:

Our school provides the IGCSE Comp Sci 0478 course (instead of ICT now), but the school’s selection of teachers are suboptimal. Despite their best efforts to teach us as much as they can, computer science is a hard subject for many and they may need a revision guide to help them.
