Teachers are asked to trust a lot of revision material that nobody has put their name to. This page exists so you can decide how much to trust ours.
Who writes it
Every teacher page names the person who wrote it and, where a second person has checked it, the person who reviewed it. Those names are not decoration. If a page carries a name, that person is answerable for what it says.
We would rather leave a page unwritten than publish one under a name that means nothing, so you will sometimes find a topic here that we have not covered yet.
What "reviewed" means
A review date on a page tells you when a person last read the whole page against the current specification and the current state of the product. It is not the date a file was edited.
A page is re-reviewed when any of these change:
- the exam board publishes a revised specification
- the revision content the page points at changes
- a reader reports something that turns out to be wrong
How specification alignment is checked
Revision content on DoRevision is mapped to a specification before any of it is written. The mapping is done against the exam board's own published specification document, not from memory and not from another revision site, and it records the topic structure and the assessment detail for that board and that subject.
Modules are then built against that map, so a module is tied to real specification points rather than to a general idea of the topic. You can see the result on the revision pages, where each specification lists its own topics and the modules that cover them, and alongside the official past papers for the same qualification.
Every question is marked on the server against a stored answer key, and the whole library is checked automatically for questions that can be answered by guessing or by spotting a pattern in the options. Content that fails those checks is rewritten before it goes live.
What we will not do
We do not publish invented quotes, invented schools, or outcome claims we cannot show the working for. Our policy on evidence and citation is set out separately, on the evidence page.
Telling us something is wrong
Corrections are welcome and we would rather have them than not. Tell us which page, what is wrong, and what it should say, and we will fix the page and move its review date.
