casestudynotes writes this week’s world news up as exam-ready case studies. Every figure is traceable to the source article it came from, and every card is tagged to the specification points that ask for a named example.
A card is written once against the thing being examined, not against the wording of one board. Choose a specification and the same archive is counted against it, then the sheet further down rules up everything that board asks for.

A free account keeps track of which ones you have.
Every case study sits where it happened. The edition below is the most recent one published, and each card opens with no account, free within a monthly limit.

This edition: Nepal, Lesotho, United Kingdom. The full map has 35 case studies in 20 countries.
A glacier collapse triggered a flash flood on the Lhende River, killing dozens and leaving hundreds missing on the Nepal-Tibet border.
A huge water transfer scheme selling highland Lesotho's water to South Africa's cities, bringing royalties, power and displacement.
The 2012 Games rebuilt polluted industrial land in east London into a park, homes and jobs, though not everyone gained.
One cell for every named example AQA A-level Geography asks for. Every cell starts open, because a cell fills when you save a case study that answers it and nothing has been saved onto this sheet yet. Each cell says how many verified cards the archive is holding for it, so you can see what is waiting behind a cell before you open it.
Every cell is open, because a cell fills when you save a case study onto it. The line on each one says how many verified cards the archive is holding for it, and a cell reading No card yet is one the archive cannot answer at all yet.
An account keeps this sheet for you, so the cells you have filled are still filled the next time you open it.

This is one card from the archive, exactly as it appears on its own page. Each figure is threaded down to the article it came from and the sentence that carries it, so a number is safe to quote in an exam.
A magnitude 7.7 strike-slip earthquake on the Sagaing Fault devastated central Myanmar during a civil war.
One figure on this card has already changed. It was first reported as 1,600 and now reads 3,471. The old number stays, with the date it changed and the source that changed it, so nobody revises from a figure that has quietly moved.

Everything on this page is free to read and no account is needed for any of it. The map, the archive, every past edition and all the evidence stay open to everyone. A free account keeps track of what you have read, and a paid plan adds the writing practice on top of it.
It keeps a bank of what you save and counts it against your specification. Everything on this page is free to read either way.

Three steps stand between a news report and a card you can revise from.
01
Every day's reporting is filtered against the concepts a specification actually asks about, before any AI touches it. A story that answers nothing on a syllabus stops there.
02
Each number carries the article it came from and the sentence it was taken from. A figure that cannot be traced back to a source article does not make it onto the card.
03
Every card is dated to the edition it ran in, so you can see how old it is. Figures are re-checked by a person as reporting settles, and the state on the card moves with them.
The state is measured from the date of the event, never set by hand and never from the day the card was published, and it is printed on the card wherever the card appears. A card about an event from last year is verified whichever edition brought it back.
The event happened within the last week. The story and the stable figures are settled. Anything still moving is flagged.
Most figures have settled. Costs and casualty counts can still be revised as reporting catches up.
Checked by a person against every source. Safe to learn.
casestudynotes is independent of every awarding body, and nothing here is an official resource. Specification titles and codes are used only to describe what each one asks for. The source behind every figure is named on the card, so a teacher can check the work rather than take it on trust.
A figure that is revised keeps its old value on the card, with the date it changed and the source that changed it.
