WJEC AS & A Level Chemistry Revision Notes & Resources

The WJEC examination board provides qualifications for schools and colleges in England, Wales, Northern Ireland and several independent regions. Comparatively, it’s a small board in the UK but we want all our teacher and student subscribers to feel supported in their A-level Chemistry studies. Thankfully, WJEC falls under Eduqas, and all six of the UK’s main examination boards have a lot of similarities and overlap. Scroll through our handy table of resources below to direct you to all the information you need to excel in your tuition, revision and examinations.
