Report an error

If something here is wrong, we would rather know. A revision site that cannot be corrected stays wrong for as long as it is up.

Write to support@inkphysics.co.uk with the address of the page and what you think is wrong with it. A sentence is plenty. If you are quoting a specification or a mark scheme, saying which board and which paper makes it much faster to check.

What happens then

Every report is checked against the source rather than taken on trust, in both directions: we have had reports that turned out to be right and reports that turned out to be a board difference rather than an error, and both are worth having. If a page is wrong it is fixed and rebuilt. If it is right, you get an explanation of why, which is usually the more interesting reply.

Things worth reporting that are not errors

A sentence that is technically true and still misleading. A diagram that does not read on a phone. A term used before it is defined. Wording that matches no board's mark scheme. Those are harder for us to find than factual mistakes, because everything here was written by somebody who already knew the answer.

Correction log

Substantial corrections are logged here by date and page; the line-by-line detail lives in the site's public change history.

14 August 2026: biology, second half of the editorial review: corrections across the immunity, inheritance, nervous system, hormones, respiration, photosynthesis, evolution, classification, ecology, gene technology, nutrition and scientific method units, with the question bank, flashcards and workbooks regenerated to match.
13 August 2026: biology, first half of the editorial review: corrections across the cells, cell cycles, molecules, enzymes, membranes, nucleic acids, exchange, plant transport and animal transport units.
13 August 2026: maths, twelve corrections from the same review, largely missing conditions and hedges on stated results.
12 August 2026: physics, corrections across the Year 12 and 13 core and the option units, plus a rewrite of the standard-error wording used in practical answers.
