AS Chemistry (Cambridge)
Cambridge AS Chemistry is the first half of the full A Level, stepping up from IGCSE into more mathematical and mechanistic Chemistry.
AS Chemistry Chemistry, at a Glance
AS is often where students first properly meet organic reaction mechanisms and more demanding calculations. Resources here are aimed at that step up specifically, rather than repeating IGCSE-level material.

Frequently Asked Questions
Is AS Chemistry a separate qualification from A Level?
AS can be taken as a standalone qualification or as the first year of the full A Level — resources here support either route.
How different is AS from IGCSE Chemistry?
AS moves faster and expects more independent application of concepts, particularly in organic chemistry and quantitative work.
Can I get help moving from IGCSE to AS?
Yes — tuition can focus specifically on that transition. See the Online Chemistry Tutor section below.
