Why our lessons work
Small classes
Never more than 10 students, so the teacher spots where your child is stuck in the same lesson.
Retrieval practice
Every lesson brings back earlier topics, so old concepts stay sharp while new ones go in.
Built around your child
Formative checks and test-paper reviews shape what each student works on next.
Aligned with school
Lessons follow your child's school, so tuition reinforces class instead of racing ahead.
How classes work
Each level has its own class, capped at ten students.
Join the class for your level
Classes are grouped by level, with up to 10 students in each.
Class full? Join the waitlist
We start a new class once three students are waiting, and WhatsApp you as soon as it's formed.
Start 1-to-1 while you wait
No lost weeks. Learn 1-to-1 with one of our teachers until your class begins.
Also available

IP Mathematics assessment books written by Mrs Wong
The same care goes into every set of notes and practice papers your child takes home.

Every teacher is chosen by Mrs Wong
Mrs Wong taught Mathematics for 27 years and was Head of Department at Raffles Institution and Nanyang Girls' High. She has written four IP Mathematics assessment books.
Every XSQUARE tutor is personally vetted and tested by Mrs Wong before they take a class.

“Not only has Mrs Wong inspired me to pursue mathematics to the best of my ability, she has also ignited my passion for mathematics education.”
“She is able to explain complex math concepts in a clear yet concise manner, which really helped me to understand the harder concepts and tackle more challenging problems.”
Izhi TanEx-student, Raffles Institution“Mrs Wong is truly one of the most caring and capable teachers that I have been privileged to be taught by and I thank her for helping me get to where I am today.”
Victor LohEx-student, Raffles InstitutionQuestions parents ask
Does XSQUARE offer a trial?
Yes. New students can start with a paid trial before committing to a term. WhatsApp us and we'll suggest a class for your child's level and school.
What happens if the class for my child's level is full?
Classes are capped at 10 students. If a class is full, your child joins the waitlist. We start a new class once three students are waiting, and we'll WhatsApp you when it's formed. In the meantime your child can learn 1-to-1 with one of our teachers.
Do you offer 1-to-1 lessons?
Yes, on their own or while waiting for a class. They use the same teachers and materials as our classes. WhatsApp us to ask about rates.
Is there a deposit for new students?
There is a one-month deposit for new students (excluding trial students). It is refunded if you give one month's notice before your child's last class.
How do I sign up?
Most parents WhatsApp or SMS us first at +65 9738 4137, or email xsquare.wnsh@gmail.com, so we can suggest the right class. If you've already decided, fill in our online registration form and we'll contact you to confirm your child's level and class.
What payment methods do you accept?
PayNow, PayLah!, bank transfer and cheque. Details are on the invoice we send you.
My child is joining mid-year. Will they miss earlier topics?
Teachers recover earlier content in our holiday programmes in March, June and September, so we encourage new students to join these crash courses.
Are there make-up lessons?
Students who miss a lesson for a valid reason, such as a medical certificate, can attend a make-up session in the same week. If no slot is available, they can book a one-hour consultation or join a holiday crash course instead. Full details are in our Terms and Conditions.
Start with a trial lesson.
WhatsApp us and we'll find a class that fits your child's level and school.
