How it works

    Write your answer; see what earned marks and what was missing.

  3. Close the gaps

    Your weak topics show up, so you know what to practise next.

Questions

Is Praxis IB part of the IB?

No. Praxis IB is independent and not affiliated with or endorsed by the International Baccalaureate Organization. IB and International Baccalaureate are trademarks of the IBO.

Are these real IB exam questions?

No. Practice questions are generated by AI in the style and format of IB exams. They are not past papers.

Is it built for the 2027 syllabus?

Yes. Topics, levels and papers follow the IB Computer Science guide for first examinations in 2027.

Which programming languages are covered?

Python and Java for Paper 2 practice. The coding exercises use Python.

How do teachers and students connect?

The teacher creates a class and shares its invite code. Students enter the code on their dashboard; they need to sign in with an e-mail address from the same school as the teacher.

What happens when a teacher’s trial ends?

The account keeps working with smaller limits (1 class of 5 students) and assigning is switched off until you upgrade.

Is my data safe?

Your data is stored securely and never sold. Lesson and video progress is deleted after 24 months without use, and you can delete it yourself at any time. See the Privacy Policy.

Can Praxis IB guarantee my grade?

No. It is a study tool to use alongside your lessons; results depend on many things.
