Two things, both free and both open in a browser: writing guides that explain what UK markers are actually looking for, and an index of research you can read and cite without meeting a paywall.
Each one takes a single piece of feedback that UK students get constantly, and explains what it means in practice — with worked examples showing the same evidence written two ways.
Too descriptive, needs more analysis — the most common line of feedback in UK marking. What it means, why it happens, and how to fix a paragraph.
Core guide · 8 min What the question verb is asking you to doDiscuss, evaluate, critically assess, to what extent. UK essay questions are instructions in disguise. A decoder for the verbs that keep appearing.
Core guide · 10 min Reading a marking rubric properlyUK band descriptors are written for markers, not students. How to translate them, where the marks actually sit, and how to work backwards from a first.
An index of openly licensed research — work published under licences that permit reuse, so you can read the full text rather than an abstract behind a paywall.
How it is put together. Every entry has had its licence checked against the publisher's own record rather than assumed from a repository label. Where a publisher permits automated access, a copy is hosted here so the link does not rot. Where it does not, the entry links out to the publisher instead. Each record credits its authors and points at the original — the library is a way of finding work, not a substitute for citing it.
Scholar is the free, open part of SafeGrade. Nothing here needs an account, and the guides carry a writing-analysis tool that runs entirely in your browser — the text you paste into it is never uploaded.
