Your tutor
MEng, University of Cambridge
Lewis read Chemical Engineering at the University of Cambridge and has worked as a full-time private tutor since 2015, teaching one-to-one to students preparing for high-stakes exams. A native English speaker based in London, he teaches both halves of the SAT himself: the Math with an engineer’s command of the quantitative section, and Reading & Writing with the ear for language the verbal section rewards.
Much of the early work was residential in the Gulf, living with families in Dubai and Saudi Arabia and teaching through term time and exam season, before the practice moved mostly online.
Student voices
“I got into UPenn!! Thank you so so much for all of your help, couldn’t have done it without you.”
SAT student · on results day“Lewis helped me get my score up from 1200 to 1400 in a month. I found the Math section particularly difficult, as I wasn’t taking a math class at school that year. The online format worked well: Lewis marked my homework on our shared document before each lesson, so we focused only on the hardest problems.”
Liora · SAT student“I think the SAT went well! I could do all of the maths questions which was good.”
SAT student · message after the exam“The online format worked so well that I started using the GoodNotes app for my other classes too. With both of us writing on the same document, lessons feel very active. I’m solving the question more or less alone, with Lewis jumping in if I go astray.”
Ahmed · SAT student“Lewis is a patient teacher who will try lots of ways of explaining a question until one method or technique feels right. He really helped me realise the power of the graphing calculator in the Math section.”
Riccardo · SAT student“Lewis sent me lots of homework and regularly checked up on it, which gave me the practice I needed to improve my score.”
Carolina · SAT studentTry the materials
These are the first four of the thirty work packs that come with tuition — the same material, in the same order, that a student receives between lessons. The first is yours with nothing to sign up for; the other three unlock with an email address below. Each opens with short drills to get the mechanics automatic, then moves into SAT-style questions at two levels of difficulty.
They are supplied without answers on purpose. Marking your own work against a key teaches you what you got wrong; it does not tell you why. That is the part we do for you, below.
Negative and fractional exponents, index laws, simplifying surds, and the rewriting questions the SAT builds on top of them.
Download worksheetFactoring, difference of two squares, adding and simplifying algebraic fractions, and the equivalent-expression questions that follow.
Download worksheet Enter your email belowRearranging for a named variable, proportion and cross-multiplication, radical equations, and the “value of the whole expression” questions that reward not solving for x.

No charge, no obligation
Do a sheet on paper, photograph or scan every page including the rough working, and send it over. Lewis marks it himself and replies with a written review: what you got right, where the marks went, and the two or three habits costing you the most points. It usually comes back within two working days.
You do not need to be a student to ask, and there is nothing to sign up for.
Or email lewis@altairprep.com directly and attach photos of your working.

Interactive by design
Judgment isn’t absorbed from videos. It’s built by doing. Every lesson happens on a live shared whiteboard: students with an iPad and Apple Pencil sketch graphs, annotate passages, and set out working in their own hand while the tutor writes alongside them in real time.
An unedited stretch of a real lesson board — 53 seconds, no sound. This is the actual tool, not a mock-up: the student writes on the same page at the same time.
Scheduling
Every time below is your local time. Book a slot in the window that suits you, and the same slot is held each week for the length of the course.
| Where you are | Available lesson times | Days |
|---|---|---|
| United Kingdom | 9:00 am to 5:00 pm | Monday to Friday |
| Central Europe | 10:00 am to 6:00 pm | Monday to Friday |
| Saudi Arabia, Qatar, Kuwait, Bahrain & Jordan | 11:00 am to 7:00 pm | Monday to Friday |
| UAE & Oman | 12:00 pm to 8:00 pm | Monday to Friday |
| Singapore & Hong Kong | 4:00 pm to 10:00 pm | Monday to Friday |
Times shown are for UK summer time; in the UK winter, Gulf and Asia times move one hour later, while UK and European times are unchanged. Weekends and school-holiday lessons are available on request, and the schedule flexes around exam season and Ramadan. In London? In-person lessons can be arranged; just ask when you enquire.
Plan ahead
The Digital SAT runs on the same dates worldwide. Most students want twelve to sixteen weeks of weekly lessons before their sitting, so we plan backwards from the date you choose, which means the best time to start is well before the registration deadline.
| Test date | Registration deadline |
|---|---|
| Saturday 3 October 2026 | 18 September 2026 |
| Saturday 7 November 2026 | 23 October 2026 |
| Saturday 5 December 2026 | 20 November 2026 |
| Saturday 6 March 2027 | 19 February 2027 |
| Saturday 1 May 2027 | 16 April 2027 |
| Saturday 5 June 2027 | 21 May 2027 |
Dates from the College Board. Registration is through mysat.collegeboard.org; late registration is available worldwide for an extra fee. Seats at international test centres can fill early, so register as soon as you have chosen a date. See every date with the deadline and when to start preparing →
Nothing left to chance
Lessons are only half the work; the marks come from the independent practice between them. Every student has a live tracker like the one below, one row per College Board topic, one column per difficulty level. Assigned work stays on the board until it is finished and reviewed, so by test day every content domain and every question style has been covered, practised, and signed off. Parents can see it whenever they like.

Fees
One rate, covering everything below; you can view the full fee sheet here. Lessons are one-to-one and typically an hour long, and billed after each one has taken place — nothing is paid in advance and there is no minimum commitment. The intro call and demonstration lesson are free.
Because homework is set and marked between lessons, students who start early in the school year and put the work in usually find once a week is enough, so a modest block of hours goes a long way. Closer to a sitting, frequency naturally steps up if it’s needed, but the aim is always the fewest lessons that reach the target score.
Equally, there is no need to sign up for weekly lessons at all. If a student is already scoring well and just wants to push those last stubborn points higher, Lewis is glad to take on a handful of sessions honed in on their most difficult problems. Often a couple of focused hours on the right question types is all it takes.
Registration for the 3 October sitting closes on Friday 18 September. The intro call and demonstration lesson are free and come first, so the earlier you ask, the more of the run-up is left to use.
Common questions
Every SAT course teaches tricks: elimination, plugging in numbers, pacing rules. They matter, because without speed you run out of clock. But the test is engineered so that its hardest questions look like trick questions, then quietly break the pattern, and students who lean on shortcuts alone stall in the low 1400s. A 1500+ score comes from judgment: knowing when the fast route is safe, and recognising the moment a question demands real problem-solving instead. That judgment is what we train — tricks for speed, understanding for everything the tricks can’t reach.
Preparation is anchored to official College Board material, with regular full-length timed mocks in Bluebook so nothing on test day is a surprise. Alongside it, Lewis brings his own bank of challenging problems, built for the current Digital SAT and kept up to date as the test changes. That means less of each lesson spent drilling questions a student already finds easy, and more on the harder problems that resist a memorised method — which is exactly where the points above 1500 are won.
One rate, set out on the fee sheet. Take lessons as and when you need them, billed after each one has taken place, with no minimum commitment and nothing paid in advance. Payment is by card link or bank transfer, and there is nothing to pay before the free intro call and demonstration lesson.
The SAT is now fully digital, taken in the Bluebook app at an approved test centre. It lasts about 2 hours 14 minutes and has two sections, Reading & Writing and Math, each split into two adaptive modules. Scores range from 400 to 1600, and a calculator is allowed throughout the Math section.
A laptop or tablet, a quiet hour, and a stable connection. An iPad with an Apple Pencil is strongly recommended, because it lets the student write directly on the shared whiteboard, which makes lessons far more interactive. A laptop works too.
Twelve to sixteen weeks of weekly lessons is a comfortable runway for most students. The SAT is offered on several international dates each year, so we plan backwards from the chosen sitting, leaving time for at least one retake before university deadlines if needed.
Yes, both Math and Reading & Writing, by the same tutor. Reading & Writing is taught by a native English speaker, which matters on a section built around nuance in vocabulary, grammar and argument; the Math is taught by the same person, drawing on a Cambridge Chemical Engineering degree and over a decade of one-to-one teaching. One tutor across the whole test, so the verbal half is never handed to an associate. Many students weight their plan towards one section based on their diagnostic; that balance is reviewed after each mock.
Yes. Parents receive short progress updates after mocks, and are welcome to join a review call at any point. You will always know the current score, the target, and the plan to close the gap.
Get started
Send the form below — the student’s year group, city and target test date are enough — and Lewis will reply within one working day with times that suit your zone. The call is a free chat about target universities, test dates and current level, followed by a 20-minute demonstration lesson on real SAT questions, so you see exactly how Lewis teaches before you pay for anything.
You will hear back within one working day. If it is urgent, write to lewis@altairprep.com.
