How to use Chemistry Help
Find what you need, then choose one useful thing to practise.
You can also use Search site in the header, or press Ctrl+K (Cmd+K on a Mac).
Choose a starting point
Revising for a test
Start with the topic your teacher set. Check the specification lines you have covered, choose a lower-rated part and use the explanation or practice links beside it. Then try a fresh question without help.
A quick brush-up
Choose one skill. Read its short explanation if needed, try a few questions and check what went wrong. Ten useful minutes can be enough for a small task.
Not sure where to begin
Choose your board’s topic page or use search. In My Chemistry, rate the specification lines you have covered honestly; leave uncovered lines blank. Ratings help you choose work, and question results give separate evidence.
OCR A topic revision · AQA topic revision · My specification tracker
Ask Coach T to help you choose. Tell him the topic, your goal and roughly how much time you have. The existing age, permission and account rules apply.
What each part is for
My Chemistry topics
Choose a course topic and start a short question round. Public topic revision pages also have explanations and linked practice.
Opening a topic does not establish mastery; independent/helped/retried answers are distinct.

Specification tracker
Rate covered lines honestly from 0 to 5, leave uncovered lines blank, and use Quick revision, MCQ and Chemistry Help links beside the line. Work on a covered lower-rated line then check yourself with a fresh question. A rating increase is the student's judgement, not an automatic grade.
Self-ratings are separate from quiz evidence. Reading notes or changing a number does not prove understanding.

Chemistry tools
Search by tool name/skill or choose an area. Some tools save checked results; others describe their own saving or self-marking limits.
A visit alone is not completion; teacher preview stays out of learner scores.

Saved questions
Return to questions saved for another attempt. Try without the worked answer, then use help if needed.
A later correct answer is distinct from a first independent answer.

Open bench laboratory
Choose board and AS/full course, then a sample or apparatus. Decide what you expect before revealing observations. This is a simulation, not proof of practical competence.
Opening or revealing an observation does not prove understanding.

Interactive organic reaction map
Choose the board and relevant topics, inspect reactions or plan a route. Follow with drawing/recall practice. Search explains when matching reactions are hidden by topic filters.
Looking at an explanation is not an independent mechanism answer.
