What you get on the platform

Six things that make the difference between „an online course" and „real exam preparation".

In-browser emulator

Write real code, see real results, no install, no database to spin up, no
risk. The SQL emulator runs directly in your browser tab.

Aligned with the CKE exam

Content, exercises and quizzes match the INF.03 syllabus and real exam papers
from 2019-2025.

Stress-free gamification

Earn XP, badges and levels. No penalty for mistakes, no point loss, no
public rankings. Your progress, your pace.

Day and night

The theme adapts to the time of day. You can also force a light or dark mode
with one click, your eyes will thank you.

Works offline

Install as an app, cache lessons once and learn on the bus, in the forest,
anywhere. Progress syncs as soon as you're online again.

Safe and GDPR-friendly

Minimum data, maximum privacy. Argon2id passwords, HTTPS-only sessions, zero
trackers, zero ads. Your account is yours.

Who it's for

Students at IT vocational schools preparing for the INF.03 exam, calmly,
without rote learning, without hunting for materials across the internet.
Everything in one place, step by step.

For teachers

Teachers who want to lead a class through a course, see each student's
progress in one panel and use it as a diagnostic tool, instead of juggling
PDFs and slide decks.

Progress you can see, that keeps you going
