Why this board

Marking OCR Chemistry properly

Quantitative chemistry is where grades are decided. Feedback shows the full working an examiner expects for moles, yields and titration calculations, and where error carried forward would have saved marks. OCR questions lean on applying knowledge to unfamiliar contexts, so the gap between knowing a topic and scoring on it is wider than on other boards. That gap only shows up under timed conditions.

Every script is read by chemistry specialists and former board examiners. You get the paper back annotated, with a topic-level percentage and an indicative grade against real boundaries, not a self-marked tick list.

FAQ

OCR Chemistry questions

Do you mark against the OCR mark scheme?
Yes. Every Chemistry script is marked against the published Oxford, Cambridge and RSA mark scheme for that paper, by an evaluator who specialises in the subject and knows the board's conventions.
How quickly does a OCR Chemistry paper come back?
48 hours from upload as standard, and 72 hours during the January and May peaks. The current turnaround is always shown before you upload.
What does the report contain?
An annotated script, marks per question, a topic-level breakdown, an indicative grade placed against published boundaries, and three prioritised next actions.
Is the marking done by a person?
Yes, chemistry specialists and former board examiners. Every mark and comment is written by a qualified human evaluator.
What does OCR Chemistry marking cost?
Topic tests are £7.99, real past papers £11.99 and full mocks £14.99. The first paper is free, with no card details taken.
