A level Chemistry notes, exams and marking guides

A -level chemistry

The secret to pass chemistry exams lies in writing and rewriting notes, questions and answers to internalise the concepts, improve on the spellings and writing skills . It upon this that you are advised to write and rewrite these notes and read  about each topic from all sources possible to widen your  knowledge .
