I'm Ansuman Mullick — an AI researcher at Bilkent University with a 790 in SAT Math and seven years of teaching behind me. I show you more than one way to solve every problem, until the ideas are genuinely yours.

// 03 · How I teach
Understanding first. Scores follow.
Memorised tricks fall apart under exam pressure. Real understanding doesn't. Here's the reaction I'm aiming for in every lesson:
confusion+curiosity1:1 lesson · Δ↓⟶understanding↑+confidence
More than one way in
I show several routes to the same answer, so you can pick the one that clicks for you and still works under exam pressure.
Concepts before speed
Speed and accuracy need something solid to rest on. We build the understanding first, then the pace follows.
Find the real gap
The approach I use in research, applied to your marks: find exactly where points are being lost and fix the cause, not the symptom.
// How lessons work
- 01
Diagnose
Our first lesson maps where you are: what's solid, what's shaky, and where marks are slipping away.
- 02
Plan
A plan shaped around your exam date, syllabus and target score — not a one-size course.
- 03
Teach
Live one-on-one lessons where you can ask anything the moment it doesn't make sense.
- 04
Practise & review
Targeted practice, timed papers and careful error review, so progress is something you can see.
// 04 · Research
I teach AI what to remember — and what to forget.
When I'm not tutoring, I'm a researcher at Bilkent University. My latest paper, Fortunate Recall, gives AI assistants a memory that behaves more like ours: facts get sorted, fade at different speeds, get replaced when life changes, and expire when they stop being true.

// 05 · About me
A researcher who loves to teach.
I started tutoring seven years ago and haven't stopped since. More than 700 students later, I've taught everything from middle-school maths to HL-level exam preparation, including instructor and curriculum-development roles with Mathnasium centres in the US, Saudi Arabia and the UAE.
Alongside teaching, I'm a computer engineer and AI researcher at Bilkent University, where I studied on a full-merit scholarship. My research looks at how AI systems keep what they know accurate over time — which, it turns out, is a lot like what good revision does for students.
Research trains you to find exactly where something breaks and fix the cause, not the symptom. I bring that habit to every lesson: we find the real gap, understand it properly, and build from there.
— and yes, I still think Fourier series are magic.
// 06 · Experience
Seven years. 700+ students.
I've taught with established tutoring organisations in the US and the Middle East, and online for students around the world.
