IGCSE Chemistry tutoring in Thai: who it suits, and how to still answer to the mark scheme in English

Tutoring in Thai suits students whose main language is Thai and who are held back by understanding rather than by English. The condition is that the terms and questions stay in English throughout, because the exam and its marking are in English.

If a student already reads and thinks fluently in English, learning entirely in English is no disadvantage. Choose whatever your child understands fastest.

Students at international schools or bilingual programmes who speak Thai at home: they keep up in other subjects, but chemistry brings new vocabulary and invisible ideas at the same time, such as moles, bonding and electrochemistry.

Students moving from the Thai curriculum to IGCSE, or sitting IGCSE without attending an international school, who have to adjust to both the content and the exam format at once.

Families where parents want to follow what their child is learning, where they are stuck and how to help.

IGCSE papers from both Cambridge (0620) and Edexcel (4CH1) are in English and marked to an English mark scheme. A student who learns only the Thai term has to translate "relative formula mass" back in their head in the exam, which costs time and risks misreading the question.

What works is explaining the idea in Thai so it can be pictured, while calling everything by its English name from the first lesson, doing questions in English and practising writing answers in English.

Asked why a higher temperature speeds up a reaction, a student who understands it often writes "particles collide more". The idea is right, but mark schemes usually look for more frequent collisions (more collisions per unit time) and more particles with energy at or above the activation energy.

A gap like this is not closed by more explanation. It is closed by writing answers in English again and again, with someone checking them against the mark scheme straight away.

If a tutor translates everything into Thai and sets only Thai questions, the student understands the content but cannot write the answers in the exam room.

Before starting, ask three things: are the practice questions exam-style and in English, are answers checked against the mark scheme, and does the student practise writing answers in English themselves?

The self-learn course comes in Thai or English, with the same English terms and question styles as the exam: interactive lessons for all 12 topics and a question bank marked by AI against the mark scheme, showing which keyword is missing. ฿4,900, paid once.

Live lessons with Boom are taught in Thai on Google Meet: 1-on-1 at ฿750/hour, or a pair of 2 at ฿600 per student per hour. Every lesson is recorded to rewatch, and parents get a summary of what was covered, where the student is stuck and the homework (recorded only with a parent's consent).

The platform is expected to open around December 2026.
