Capabilities

Tools 11

class_summary

For a teacher's own exam.now class: topic bands across the class with no pupil names, and how many pupils have started. Small groups are suppressed to protect pupils' privacy.

Discovered
common_mistakes

Up to 5 exam.now write-ups of common mistakes in a subject, drawn from Cambridge examiner reports, each with a short summary and a link. Narrow them with a topic code or words.

Discovered
exam_timetable

Cambridge exam dates for one or more syllabuses in the June or November 2026 series: component, date, morning or afternoon session and duration, with a link to the exam.now timetable. Zone defaults to the UK timetable.

Discovered
find_past_paper

Find Cambridge, AQA or Edexcel past papers on exam.now from a free-text query such as "0580 june 2024 paper 4" or from structured fields. Returns up to 10 papers with their exam.now paper_id, title, session, duration, total marks, whether exam.now can show it on screen to answer (answer_on_screen, with the parts that need a graph or drawing and so can only be answered there), and links to the question paper, insert, mark scheme and examiner report where they exist. Use the paper_id with get_question, get_mark_scheme or get_paper.

Discovered
find_questions_by_topic

Past-paper questions on exam.now tagged with a syllabus topic, newest first. Pass the topic code (e.g. E2.5) or words (e.g. "simultaneous equations"). Returns question references with the start of each prompt, marks, whether it has a figure, and a link to the question.

Discovered
get_mark_scheme

The official mark-scheme rows for one part of an exam.now past paper: each row's code (M1, A1, B1…), marks, answer, guidance and alternatives, the part's maximum marks, the paper's general marking principles, the mark-scheme PDF page and a link to it on exam.now.

Discovered
get_paper

An exam.now past paper as structured JSON (metadata, questions, parts, prompts, marks, answer kinds, figure URLs), a few questions at a time. Each part's answer.onSite is true when it needs a graph or drawing and can only be answered on exam.now; the other parts can be typed in chat for mark_answer. Use next_from to get the next page. include_mark_scheme adds the mark-scheme rows for the same questions and needs a linked exam.now account (a free one is fine).

Discovered
get_question

The text of one question or part from an exam.now past paper: context, prompt, marks, figures (with alt text), the answer surface (response kinds, tools, whether a calculator is allowed), topic codes and a link to the part on exam.now. answer.onSite is true when the part needs a graph or drawing, so it can only be answered on exam.now; otherwise the student can type the answer in chat and mark_answer marks it. Pass question for the whole question or part for one part.

Discovered
mark_answer

Mark a student's answer to one part against the official mark scheme with exam.now's marker. Returns marks awarded and available, the mark-scheme rows earned and missed, feedback and a common-mistake link, and saves the mark to the student's exam.now progress. Needs a linked exam.now account with marking.

Discovered
practise_question

Show one past-paper question as a practice card the student can answer, with its figures and answer surface. The model gets the full question so it can give hints without giving the answer away. Use mark_answer to mark the student's answer.

Discovered
topic_progress

The linked student's own progress in one subject on exam.now: each syllabus topic's band (secure, getting there, not yet), the next three topics to work on (weak topics first, then topics with too few marks to band and untried topics that are ready to start, each with a reason) and links to practise them.
