Super Admins can create sub-admins and assign specific permissions. This lets you delegate tasks like license generation or question uploading without giving full system access.

The admin dashboard is a static HTML file served by the Node.js admin server.

To deploy to your htdocs/server:

# 1. Copy the admin-server folder to your server
# 2. Install dependencies on the server:
npm install --production

# 3. Start the server (use pm2 for persistence):
npm install -g pm2
pm2 start server.js --name chilex-admin
pm2 save

# The admin panel will be at: http://yourserver.com:4000

Update the BACKEND_URL in index.html to your server's public URL before deploying.

Go to My Profile to update your display name, phone number, and avatar. Changes are saved when you click the Save button.

You can add mathematical equations and scientific symbols in questions using LaTeX syntax. The system uses MathJax to render formulas.

Inline Math — wrap in $...$ (for within a sentence)

$x^2 + y^2 = z^2$
$\frac{a}{b}$
$H_2O$
$\sqrt{x^2 + y^2}$

Display Math — wrap in $$...$$ (for standalone equations)

$$\frac{-b \pm \sqrt{b^2-4ac}}{2a}$$
$$\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$
$$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$

Common Symbols:

Type	Syntax	Output
Fractions	$\frac{a}{b}$	a/b
Square Root	$\sqrt{x}$	√x
Superscript	$x^2$	x²
Subscript	$H_2O$	H₂O
Plus/Minus	$\pm$	±
Infinity	$\infty$	∞
Alpha	$\alpha$	α
Beta	$\beta$	β
Pi	$\pi$	π
Degree	$90^\circ$	90°

These formulas will also render correctly in the student exam pages.
