Co znajdziesz na platformie
Pełne przygotowanie do części praktycznej i pisemnej egzaminu zawodowego INF.03.
Wirtualny komputer egzaminacyjny
Każda lekcja kończy się ćwiczeniami, które wykonujesz na wbudowanym emulatorze prosto w przeglądarce: piszesz prawdziwy kod SQL, PHP, HTML, CSS i JavaScript, uruchamiasz go i od razu widzisz wynik. Dokładnie tak, jak przy zadaniu na egzaminie, bez instalowania czegokolwiek na swoim komputerze.
Do tego trenażer części pisemnej z bazą pytań w stylu CKE oraz egzaminy próbne na czas. Zobacz wszystkie kursy →
Najczęstsze pytania
How much do the courses cost?
Check the full pricing on the Pricing page, you can buy courses individually or in a bundle at a discount. One-time payment, no subscriptions. Want to try first? Visit the free demo, a few lessons and a working emulator, no sign-up required.
Do I need to install anything?
No. Everything runs in the browser, including the SQL emulator. You can
additionally install the platform as an app (PWA) with one click, but that's
optional.
Is my data safe?
Yes. We collect only your email, first name and class label. Passwords are
hashed with Argon2id, all traffic goes over HTTPS, sessions are isolated. We
don't sell data, we don't have ad trackers, we show no ads.
What if I forget my password?
Click "Forgot password" on the login screen, enter your email and you'll get
a link to set a new password. The link is valid for one hour.
Does it work on a phone?
Yes, the UI is responsive. On a phone, theory lessons and quizzes work best.
For writing complex SQL queries we recommend a laptop or a tablet with an
external keyboard.
Can I learn offline?
Yes. Once you open a lesson its content is cached in your browser and you can
return to it without the internet. Quizzes and the exam simulation require a
connection (to save your results).
Is the content aligned with the current syllabus?
Yes. The SQL course covers the full scope of the INF.03 exam, split into
modules following the structure of CKE exam papers. We update the content as
CKE changes the syllabus.
I have more questions: how can I reach out?
The fastest path is your teacher, the one who enrolled you in the course.
