About this site

chemistryaleveltutor.com is run by aleveltutors.online Limited, an A-level tutoring business with a small team of specialist tutors. The site exists to give OCR chemistry students the past-paper material they actually use, sorted the way they revise, free and without sign-up; and to introduce students who want more help to a tutor who teaches the OCR specification every week.

Where the material comes from

• Questions, mark schemes and examiner comments are from OCR's own published papers for every Chemistry A series since June 2016 (H032 AS from 2016, H432 A level from 2017): 47 papers and 1,820 question parts. Each part has been tagged to the learning outcomes it assesses, its maths skills and Practical Activity Group, and its question type. Where a part needs a table, graph or structure printed in an earlier part of the question, that earlier part folds out above it.
• Difficulty ratings (Easy, Medium, Hard) come from the wording of OCR's examiners' reports on each part. OCR's reports do not give facility figures, and parts the report does not discuss are left unrated.
• Key-term cards and topic notes are written by our tutors and are original; nothing derived from OCR's material is generated automatically.
• Grade boundaries and exam dates are OCR's published figures.

Who writes it

The tutoring is by a specialist OCR chemistry tutor; see the tutor page. The site is built and maintained by the same small team that runs alevelbiologytutor.com, mathsaleveltutor.com and alevelpsychologytutor.com.
