About Kleksa
Kleksa is an online trainer for school-leaving and entrance exams, built for students who want to know where they stand and what to practise next. It prepares for exams in Poland, Ukraine, Romania, Czechia, Kazakhstan, Austria, the Netherlands, France and Spain.
Our Mission
We believe that an exam is easier to pass once you have practised it in its real form. Kleksa brings the official papers, practice in the exam's own format and marking by the official criteria together in one place — affordable for every student, not just those who can pay for private lessons.
What Makes Us Different
- The real exam format — official past papers and our own mock tests, timed like the real exam
- Marking by the official criteria — tasks with an answer key are checked at once, and open answers are marked against the authority's marking scheme
- Practice where you are weak — a trainer that picks tasks from your weakest topics and brings your mistakes back for review
- A tutor for every topic — it explains a task step by step instead of just giving the answer
- A free start — a full test with your score, no account needed
- Transparent pricing — a one-off pass or a monthly plan per subject, no hidden fees
Independence and Sources
Kleksa is an independent service. It is not run by, affiliated with or endorsed by any exam authority or ministry of education. Past papers are reproduced with attribution to the authorities that publish them, and the tasks we write ourselves are marked as ours.
