Flashcards for OCR A-level Chemistry A (H432), split into Modules 1 to 6 as the specification does and then by topic in its own numbering, with a Practical activities section covering the method, apparatus and observations of PAG1 to PAG11. Written from the specification for exams from 2027 (version 3.1). Delete or suspend any subdeck your course leaves out once the deck is yours.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.
