TestKo

An exam-prep platform for students in Kosovo. It recreates the national exams exactly — same number of questions, same clock, same answer sheet — and explains every mistake.

Students find out how ready they are on exam day.

The state Matura is 100 questions across four subjects in two and a half hours. Past papers exist, but practising with them means no clock, no score and nobody to explain what went wrong. TestKo wanted students to sit the real exam as many times as they need, before it counts.

The real exam, on the phone and on the web.

A timed “real test” mode that mirrors the paper exam — question count, clock and answer-sheet map — built on more than 2,000 official questions from past state tests, and a practice mode that explains each answer straight away. Scores are calculated on the server, not the device. Students see a predicted score, results by subject and practice aimed at their weakest topics, with maths rendered properly. The Nuxt website handles accounts, pricing and card payments through the bank’s 3-D Secure page; an admin panel imports questions and controls payments.

One account, every screen.

The website and the React Native app share one Supabase backend and one login, so a student who upgrades to Pro on the web — €4.90 a month, with no auto-renewal — is unlocked in the app straight away, without app-store purchases. The Matura track is ready; the grade 9 national test, faculty entrance exams and university exams are mapped out next.
