By subject and semester. With clear priorities.

Subjects sit like books on a shelf. Each lesson explains one section in short paragraphs, with schemes, worked examples, traps and tips.

Each part of a lesson sits behind a card: say it yourself, then reveal, so you know right away what has stuck.

You put exam schemes in the right order from memory, and fill in rules and terms yourself in cloze exercises.

Why it works: Visible priorities steer limited study time to where it pays off most. Producing the structure yourself beats reading it (generation effect).
