# Revise — what it does, and what it cannot yet do

> Revise is evidence-based WJEC A-level revision, Physics first. Four WJEC A-level subjects are authored to their specification; no questions have been through human review yet, so Revise cannot yet prove an improvement.

WJEC A-level revision, Physics first: the one thing to do next, and honesty about what cannot be proven yet.

## What it does

- Spaces what you have to remember using FSRS, a scheduler that predicts what you are about to forget.
- Marks answers against a mark scheme written the way an examiner would mark them, and says which scheme point each mark came from.
- Turns lost marks into a named, scheduled repair rather than a list you never return to.
- Keeps your work on your own device. Nothing is sent anywhere unless you switch sync on yourself.

## What it cannot do yet

> **No question has been through human review yet.**
>
> Four WJEC A-level subjects — Mathematics, Biology, Chemistry and Physics — have their topics and specification statements authored. None of their questions have been signed off by two independent human reviewers, and Revise will not count an unreviewed question as evidence.
>
> Practising works. Proving that you have improved does not, yet: until questions are reviewed, Revise can tell you what you lost marks on but cannot certify the fix. It says so on screen rather than showing a confident claim it cannot back.

## Why that matters

A revision app that quietly counts its own questions as trustworthy will tell a student their understanding has improved, on the strength of material nobody checked. Most exam-award software has that problem. The review gate is the part worth keeping.

## Using it

The app needs JavaScript, because your revision history lives in your browser's own database and nothing is sent to a server to read it back. Turn JavaScript on and open [the app](https://revise-gray.vercel.app/), or add dates to `/settings` at any point — a plan without exam dates is still a plan.
