Your tutor
graduated IB
with a 43.

That's not a sales line — it's the reason every lesson at Intellix is built around real understanding, not memorised steps. I know the syllabus, the mark scheme, and the exact moments where students lose marks. So we fix those, properly.

The intro call is free and takes 20 minutes. No commitment required.


The lesson is just
the beginning.

Most tutors show up, explain something, and leave. At Intellix, each session is one part of a continuous cycle — so students keep improving between lessons, not just during them.

Step I

The Lesson

We work through the topic together — building understanding from first principles, not shortcuts. Every session ends with clarity on what to practise next.

Step II

The Worksheet

I prepare a custom set of practice problems — targeted at exactly what was covered. The student works through them independently, applying what they've just learned.

Step III

The Feedback

I review every answer. Misconceptions get corrected before the next session, gaps get flagged early, and nothing slips through unnoticed. Progress compounds.

Alex Ćetojević — Online IB Math Tutor
43/45
IB Score

Tutored by someone
who's been there.

I'm a maths graduate and former IB student who graduated with a 43/45 — including a 7 in Mathematics AA HL, a 7 in Physics HL, and an A in my Mathematics Extended Essay.

That experience isn't just a credential. It means I understand exactly what IB students face — and I know how to help them navigate it strategically and confidently.

  • BSc in Mathematics with a very high GPA (29.3/30) from the University of Trieste.
  • 600+ hours tutoring IB, SAT, and university-level maths and physics across international schools in Europe.
  • Former youth national team beach volleyball athlete — bringing discipline and a growth mindset to every session.
  • Teaching style: calm, structured, clarity-driven. Students understand concepts deeply, not just memorise methods.

What families say.
