Providing free IGCSE resources for everyone!
This website uses Material Design 2 for components and design guidelines because Material 3 does not support the web yet and looks worse.
The SSR system was built using my own TypeScript library called webity which can integrate with express neatly.
A FORK and STAR shows that you support this project!
There is a SvelteKit version of this web app available that has structured questions.
The license is a modified GNU license. You must:
- include a copy of the
LICENSEfile in your own version - release your product under the same open-source license
Essentially, you can do anything you want to the code as long as your version is open-source and you credit the author. The whole point is to keep things free and transparent.
The /api route is a JSON API can be used to fetch information about website content like notes or questions.
The /api/search route is meant for searching pages and extracting useful information. There is no need to use Algolia or Google Search to index pages.
// file searching might need some tweaking if different file types are included other than .html in views
app.get('/api/search', (req, res) => {
const regex = /<\/*[A-z0-9 ="#%{}.\$/:-]+>/g
const { query } = req
console.log(query)
if (!('q' in query) || !query.q) return res.status(404).json({ error: 'empty query' })
if (query.q === '*') query.q = ''
const result = {}
const icons = {
'mathematics': 'calculate',
'computer_science': 'terminal',
'biology': 'microbiology',
'chemistry': 'science',
'physics': 'speed',
}
if ('scopes' in query) {
for (const scope of query.scopes.split(',')) {
if (!Object.keys(icons).includes(scope)) return res.status(404).json({ error: 'invalid scope' })
const icon = icons[scope]
const topics = fs.readdirSync(`views/courses/${scope}`).filter(file => !file.endsWith('.html'))
for (const topic of topics) {
const notes = fs.readFileSync(`views/courses/${scope}/${topic}/content.html`, 'utf-8').replaceAll(regex, '')
if (contains(notes, query.q)) {
result[topic] = {
text: notes,
path: `/courses/${scope}/${topic}`,
icon,
topic: true,
}
}
}
}
return res.json(result)
}
const courses = fs.readdirSync('views/courses')
for (const course of courses) {
const content = fs.readFileSync(`views/courses/${course}/content.html`, 'utf-8').replaceAll(regex, '')
const icon = icons[course]
if (contains(content, query.q)) {
result[course] = {
text: content,
path: `/courses/${course}`,
icon,
topic: false,
}
}
const topics = fs.readdirSync(`views/courses/${course}`).filter(file => !file.endsWith('.html'))
for (const topic of topics) {
const notes = fs.readFileSync(`views/courses/${course}/${topic}/content.html`, 'utf-8').replaceAll(regex, '')
if (contains(notes, query.q)) {
result[topic] = {
text: notes,
path: `/courses/${course}/${topic}`,
icon,
topic: true,
}
}
}
}
res.status(200).json(result)
})It might be a good idea to view the webity documentation before you continue development.
Templates are placed inside
%{}%special brackets that return strings as plain text.
Make sure to install all dependencies before you run your project.

The webity templates are extremely flexible. The $ selector can be used to identify a file by its path starting from the views directory.
<!DOCTYPE html>
<html lang="en">
<head>
<!-- renders views/meta.html -->
%{ include('$meta.html') }%
<!-- renders the title string -->
<title>%{ title }%</title>
%{ include('$lib.html') }%
</head>
<body>
%{ include('$appbar.html') }%
%{ include('$drawer.html') }%
<main class="mdc-top-app-bar--fixed-adjust">
<!-- renders ./content.html relative to the current webity path -->
%{ include('content.html') }%
</main>
%{ include('$root.html') }%
</body>
</html>Other parameters can be passed through webity to dynamically set src and href properties.
<!-- renders ./animations.js for HOME and ../../animations.js for COURSES -->
<script src="%{ path + 'animations.js' }%"></script>
<script src="%{ path + 'script.js' }%"></script>Revision notes are under construction!
Selective questions and theory questions can be accessed through the /api/questions route.
subject: the snake case subject nametopic: the snake case topic name
The response is a JSON file with a selective and a theory field. An example with the expected data types is shown below. These fields may slightly change over time.
interface Response {
selective: [
{
intro: string,
statements: string[],
image: string,
question: string, // length > 0
difficulty: number, // [0, 1, 2, 3]
options: string[], // length = 4
scheme: number, // [0, 1, 2, 3]
explanation: string // length > 0
}
],
theory: [
{
intro: string,
statements: string[],
image: string,
question: string, // length > 0
difficulty: number, // [0, 1, 2, 3]
scheme: string[], // length > 0
explanation: string // length > 0
}
]
}This the rough idea for text-davinci marking.
Mark this student's answer. Your response should only include a JSON object with a "marks" field. The bold words in the "scheme" field mean that the student should not be awarded the mark if their answer does not contain the exact phrase in bold!
{
"answer": "aerobic respiration releases more energy than anaerobic respiration and produces no lactic acid",
"scheme": [
"aerobic respiration releases more energy **per glucose molecule**",
"no lactic acid is produced in aerobic respiration"
]
}The expected result is a JSON object with a marks field of 1 after applying the IGCSE marking rules.
There are free hosting platforms like render and cyclic! Make sure to set environment variables before you deploy your app.
