IB Maths Tutor in Bangkok — Analysis and Approaches, HL and SL

Most families get in touch at one of three moments.

The first DP1 report that doesn’t look like any report before it.

The point midway through DP2 when the Internal Assessment stops being something to think about later.

Or the week after mocks, when a predicted grade arrives that nobody was expecting.

Almost none of these students are bad at mathematics. Most of them were good at it until fairly recently, which is precisely what makes it so unsettling.

Where students lose marks at HL

Analysis and Approaches HL is a genuine step up, and not only in difficulty. It changes what is being asked.

Paper 3. Two long problems, one hour, 20% of the grade. It asks students to keep a line of reasoning going across a whole question, which nothing before the Diploma really trains them for.
The Internal Assessment. Another 20%. Most of the marks are decided when the topic is chosen, not when it’s written up. Pick something too simple and there’s no route to the top bands.
HL-only content. Complex numbers, 3D vectors, Maclaurin series, differential equations. It arrives fast and it builds on itself.
Relying on the calculator. It works in Paper 2 and hides gaps that show up in Paper 1.

This comes up a lot. Families arrive mid-course and a student who was doing fine somewhere else suddenly isn’t.

In my experience that’s rarely a knowledge problem. Usually they’re writing maths the way their old system taught them and the IB is marking it differently. That’s a much faster fix than re-teaching content — but you have to work out which one it is first, and that’s what the first session is for.

Bangkok schools take different routes to the Diploma

Not every school here gets to the IB the same way. Some run IGCSE first and then the Diploma. Others run IGCSE and then A-Level. A few are full IB from primary onwards.

This matters if you’re moving your child between schools, or weighing up which one to choose. I teach IGCSE maths, A-Level maths and IB Maths AA, so I can pick a student up wherever they are and stay with them if the route changes.

Frequently Asked Questions

FAQs

My child was strong at maths and has dropped off since starting DP1. Is that normal?

Very. Higher Level asks for extended reasoning and clear mathematical writing, which nothing before DP requires. Capable students often read the dip as a loss of ability rather than a change in what’s being assessed. It’s usually recoverable, and the sooner it’s addressed the less it affects their confidence.

We've just moved from another curriculum. Where do you start?

By establishing what your child actually understands, which is frequently different from what their marks suggest. Students transferring in often need recalibrating to IB assessment style rather than re-teaching content — those need quite different responses, and getting it right early saves months.

How much do you charge?

Rates are agreed individually, depending on level, frequency and the work involved. I take a limited number of students each academic year. The assessment call is free, and there is no obligation.
