e^{i\pi} + 1 = 0

\int_0^1 x^2 \, dx = \tfrac{1}{3}

\frac{d}{dx} \sin x = \cos x

\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}

a^2 + b^2 = c^2

\lim_{x \to 0} \frac{\sin x}{x} = 1

P(A \mid B) = \frac{P(A \cap B)}{P(B)}

\binom{n}{k} = \frac{n!}{k!\,(n-k)!}

Basic supervision: what we do and what we do not

Honest, not an anti-cheating claim.

What we do

Full screen is required on computers. Leaving full screen shows a warning and is recorded with its duration; the exam keeps running.
Switching tabs or apps is recorded with its duration, using the browser's visibility and focus signals.
Copy, paste, and right-click are disabled in the question area; attempts are counted.
One device per attempt. Opening it on another device closes the previous session and is recorded.
Official time comes from the server; the device clock offset is recorded, and answers cannot change after submission or the deadline.

What we do not do

No camera or microphone.
No screen recording, and screenshots cannot be prevented.
No face detection or AI monitoring.
No score changes and no automatic disqualification. Records appear as they are in the report; you, your parents, or your teacher decide what they mean.
On iPhone/iPad full screen is not available from the browser; focus mode and app-switch records are used instead.

Try Out does not affect stars, XP, or the adventure map. Results reach the mastery map only through deterministic scoring, as input for module recommendations.
