What does IGCSE Chemistry exam prep cost? Live tutoring vs an AI course

Cambridge IGCSE Chemistry (0620) has 12 topics, from states of matter, stoichiometry and electrochemistry to organic chemistry and chemical analysis. Cambridge designs it for about 130 guided learning hours, most of which the school teaches.

Edexcel (4CH1) covers very similar content, grouped differently and with a different paper format.

It depends on how much the school has covered. With a solid foundation, about 15–20 hours of exam prep is enough; with a shaky one it can take 30–40 hours.

Exam prep is not only about understanding. IGCSE papers are marked to a mark scheme, so a right idea without the key words can still lose marks. Students need to practise answering to the point until it becomes a habit.

Going by the prices freelance tutors and institutes in Thailand publish online (October 2026), 1-on-1 IGCSE tutoring runs at about ฿800–1,370 an hour. Freelancers tend to sit at the lower end, institutes at the upper end, and groups cost less per student.

Multiplied by the hours needed, a solid foundation comes to about ฿12,000–27,400, and a shaky one up to ฿24,000–54,800, before exam entry fees.

Live lessons pay off most for concepts that will not click on your own, for exam strategy, and for students who need someone to keep them going.

But most exam-prep time is doing questions and finding out straight away where you went wrong. That does not need to be paid for by the teacher's hour.

The Boom-Tutor self-learn course costs ฿4,900, paid once, with access until your exam session: interactive lessons for all 12 topics, a question bank marked by AI against the mark scheme, and auto-marked mocks. It is one price whatever the foundation, so the more time a student needs, the more it saves.

Stuck on something the AI explanation did not fix? Book a 1-on-1 lesson with Boom (฿750/hour); complete 70% of the course and 2 mocks and the rate drops to ฿600/hour for up to 6 hours. Live time goes where a person is really needed.

0% card instalments for both the course and the 10-hour live pack (฿7,500, course included). Change your mind on a live pack and unused hours are refunded; the course can be refunded within 7 days if no more than 2 topics have been studied.

Groups of 2–4 friends can learn together at ฿600 per student per hour, and families without a tutoring budget can apply for a ฿990 scholarship place, 10 per exam series.
