Flashcards for South African NSC Life Sciences, split into Paper 1 and Paper 2 and then by topic, following the Department of Basic Education's examination guidelines. Genetics crosses and blood grouping use worked examples of their own. 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.
