Scoring transparency
How the review estimate is built
Coursework Grade Studio is a revision aid. It estimates where a draft currently sits and identifies what to improve first; it cannot award or guarantee an official IB mark.
What the review uses
The student selects the assessment type and supplies subject, course, level, title, and prompt or research question where required. The review then applies assessment-specific criteria to the supplied draft, looking for evidence such as focus, analysis, evaluation, structure, and use of supporting material.
What “120 scored examples” means
The current calibration set contains 120 examples with known scores. They are used to compare scoring patterns and reduce obvious drift. That number describes calibration coverage; it is not an accuracy percentage, an independent validation study, or a promise that a school or examiner will award the same mark.
What the result contains
A full review gives an estimated total, criterion-level reasoning, priority weaknesses, and a revision plan. Rubi follow-up uses the review context to help the student understand and apply that feedback. The product does not write the submission for the student.
Where the estimate can be wrong
Results depend on the correct assessment context, readable draft text, the quality of the supplied prompt, and judgment calls within the rubric. Teachers and examiners may interpret evidence differently. Drafts that are incomplete, use unusual formats, or rely heavily on diagrams and appendices may receive a less reliable text-based estimate.
Privacy and providers
Signed-in account and review storage uses Supabase. Payments use Stripe-hosted checkout. When enhanced review is enabled, draft text and assessment context may be sent to the OpenAI API to produce structured feedback. Anonymous funnel analytics use random browser and session identifiers and do not include email addresses or draft content. Read the privacy policy for the full explanation.
How to use the result responsibly
Treat the estimate as a diagnostic starting point. Check each recommendation against the official rubric and your school’s academic-integrity rules, then use the report to prepare specific questions for your teacher or supervisor.
