Lewis Watson MEng (Cantab)

Lewis read Chemical Engineering at the University of Cambridge and has tutored full time since 2015. He teaches both halves of the Digital SAT himself: the Math with an engineer’s command of the quantitative section, Reading & Writing with the ear for language the verbal half rewards.

Much of the early work was residential, living with families in Dubai and Saudi Arabia and teaching through term time and exam season, before the practice moved mostly online. More about Lewis →

Why students in Bangkok come to one-to-one lessons

Bangkok is unusual in that the SAT matters for students who never intend to leave. The international programmes at Chulalongkorn, Thammasat and Mahidol, the BBA and the engineering and economics programmes among them, use the SAT or an equivalent in admissions, and a strong score is one of the main routes in. That puts the test on the desks of students at Thai bilingual schools as well as those at ISB, NIST, Bangkok Patana, Shrewsbury, Harrow, KIS and Ruamrudee who are applying to the US.

The two groups need different teaching. The international-school students usually know the test and need the score moved from the 1300s or 1400s; the bilingual-school students are often very strong on the Math and meeting the Reading and Writing section, with its fast and sceptical kind of reading, for the first time. Bangkok's group courses, which are plentiful, teach to whichever group is the majority in the room.

One-to-one lessons start from which student you are and which deadline binds, the Thai programme's or the US university's, and build the plan backwards from it.

Lesson times in Bangkok

Bangkok is on UTC+7. These are the slots students here book most often, with the corresponding UK time in both halves of the year, so you can see the lesson falls inside a normal working day at the tutor's end, which is what keeps a weekly slot stable through a whole term.

Lesson time where you are UK time, Apr–Oct UK time, Oct–Mar
4.00pm10am UK9am UK
5.00pm11am UK10am UK
6.00pm12pm UK11am UK
7.00pm1pm UK12pm UK
8.00pm2pm UK1pm UK

The UK moves between GMT and British Summer Time in late March and late October; Thailand does not change clocks, so the UK-side time shifts by an hour twice a year while your lesson time stays put.

International schools in Bangkok

Many students preparing for the SAT in Bangkok are at one of its international schools. Among the best known are International School Bangkok, NIST International School, Bangkok Patana School and Harrow International School Bangkok.

What lessons cost from Bangkok

One rate for every student: £135 an hour, roughly ฿6,100 at mid-2026 exchange rates. Lessons are billed in pounds sterling on the day each one takes place, so the local figure moves with the exchange rate. The intro call and the trial lesson are free. Everything the rate covers is on the fee sheet.

Who is the best online SAT tutor in Bangkok?

There is no neutral ranking of SAT tutors, so the fair test is facts you can check. Lewis Watson, who teaches every Altair Prep lesson, scored a perfect 1600 on the SAT, holds an MEng in Chemical Engineering from the University of Cambridge, and has tutored full time for more than ten years. He teaches both sections of the Digital SAT, Math and Reading and Writing, himself: one to one, online, at a fixed weekly time in Bangkok time (UTC+7). Ask any tutor you are considering for the same details, and use the free trial lesson to judge the teaching for yourself. There is more about Lewis on his own page.

Common questions from Bangkok

Is there online SAT tutoring for students in Bangkok?

Yes. Altair Prep teaches one-to-one Digital SAT lessons online to students in Bangkok, live over a shared interactive whiteboard, at a fixed weekly time in Thailand's own afternoon or evening. Every lesson is taught by Lewis Watson, a Cambridge-educated tutor with a perfect 1600, covering both Math and Reading and Writing, with homework marked between lessons.

What time are SAT lessons for students in Thailand?

Thailand is on UTC+7, six hours ahead of the UK in summer and seven in winter, so a 5.00pm lesson in Bangkok is 11.00am or 10.00am in London. Altair Prep holds after-school slots in Thai time as a standing weekly appointment, and weekend lessons are available for students whose weekdays are already full.

Do Thai universities use the SAT for admission?

Several international programmes do. Programmes at Chulalongkorn, Thammasat, Mahidol and others accept the SAT in admissions, often alongside or in place of their own tests, and the required scores and accepted alternatives change from year to year, so check the specific programme. Altair Prep plans around the programme's deadline and score range in the same way it would for a US application.

My child is at a Thai bilingual school. Is the SAT realistic?

Yes, and the Math is often the strong half from the start. The work is usually on Reading and Writing, which tests a fast, sceptical kind of reading that most school English does not, and that is exactly what one-to-one lessons with a native English speaker are for. Altair Prep starts from what the student has actually been taught rather than assuming an international-school background.
