When are the 2027 E Math classes?

There are 5 E Math classes a week across Sec 3 & Sec 4, on Wednesday, Thursday, Sunday and Saturday. See the 2027 timetable above for each level's day and time, and WhatsApp us to check for seats.

How much are the fees?

$320 a month for one subject, $600 a month for 2 subjects, $880 a month for 3 subjects. Each month has 4 lessons per subject.

Is this for the O-Levels or the new SEC?

From 2027, Sec 4 students sit the Singapore-Cambridge Secondary Education Certificate (SEC), which replaces the GCE O-Level. Much of the E Math content carries over from the O-Level syllabus, so well-chosen O-Level past-paper questions are still useful practice. Our lessons follow MOE's latest E Math syllabus, so your child prepares for the exam they will actually sit.

What's the difference between G2 and G3 E Math?

Under Full Subject-Based Banding, students take Math at the level that suits them. G3 goes further into some topics and has more demanding questions than G2. In 2027, Sec 3 E Math has separate G2 and G3 classes, so your child is taught for the paper they will sit.

My child understands the work in class but loses marks in exams. Why?

It's usually exam technique, not understanding: skipped working, missing reasons in geometry, misread questions and running out of time. These are fixable with practice on exam-style questions, which is how our lessons are taught.

Sec 3 & 4 E Math · G2 and G3

Upper Sec E Math. Every Topic Covered. Exam Ready.

Q: My child is weak in Sec 2 Math. Should we start now or wait for Sec 3?

Start now. Sec 3 E Math builds directly on Sec 1 and 2 algebra, so gaps left in Sec 2 show up again in Sec 3. Our Sec 3 Headstart holiday classes cover key Term 1 topics before school starts, or begin with a free diagnostic assessment.

Q: What happens if I am unable to attend a particular lesson?

Students may attend a make-up lesson on other days of the same week if they are unavailable (provided the subject lesson is available). Otherwise, students can access the recording for the class they have missed to catch up on the missed content. Please note that there will not be any refunds or pro-rating of the fees.

Q: What is your class size policy?

Our Secondary classes have at most 8 students and our Primary classes at most 6, so the tutor can give every student attention. For one-to-one lessons, we also offer private coaching.

Q: How do I get started?

WhatsApp us or send an enquiry through our contact form. We'll understand your child's needs, recommend a suitable class, and you can start with a free diagnostic assessment.

At KLS, we provide a focused curriculum in line with the MOE Singapore guidelines for Upper Secondary Mathematics. Our courses are designed to build critical skills in Algebra, Geometry, Trigonometry, and Statistics.

Common mistakes

Where Sec 3 and 4 students lose marks in E Math

E Math covers a wide range of topics, so marks slip away in many small places, not one big one. These are the mistakes that cost students the most marks.

Getting reverse percentages backwards

If a price after a 20% discount is $80, the original price is $80 ÷ 0.8 = $100, not $80 × 1.2 = $96. Students who add the percentage back on get these questions wrong every time.
Cancelling terms instead of factors

In an algebraic fraction, only common factors cancel. (x + 3)/(x + 6) is not 1/2. Factorise the top and bottom first, then cancel what's left in common.
Using the wrong scale factor for similar figures

If the lengths are in the ratio 1 : 2, the areas are in the ratio 1 : 4 and the volumes 1 : 8. Using the length ratio for an area or a volume is one of the most common slips in this topic.
Leaving out the reasons in geometry

When a question asks for reasons, the angle on its own isn't enough. Each step needs its property, such as “angles in the same segment” or “angle at centre = 2 × angle at circumference”.
Forgetting “without replacement” in probability

If 2 of 5 balls are red and two are taken without replacement, the chance both are red is 2/5 × 1/4, not 2/5 × 2/5. The numbers change after the first ball is taken out.
Misreading the scales on graphs

Each axis can have a different scale, and a line that slopes down has a negative gradient. Check the scale on both axes before reading off a value or working out a gradient.

How we fix them

Your child's free diagnostic assessment shows which of these mistakes they make. In class, tutors work through exam-style questions and show the full working and reasons that earn the marks. Every lesson is recorded for revision, and Sec 3 E Math has separate G2 and G3 classes, so lessons match the paper your child will sit.

Failing since Sec 1 → A1 in Sec 2

“My son (Sec 2) started 2 lessons before WA1 and managed to get a B4. Before that, he had been failing Math since Sec 1, his foundation was very weak and he had no interest because he couldn’t understand anything. … By WA2, my son improved to an A1. … We’ve tried a few Math tutors over the past couple of years but never found the right one. Desmond is definitely different and is the kind of tutor many parents are looking for.”

E8 → A2 A Math · B4 → A1 E Math

“My child was struggling with AMath and EMath. With Desmond’s support, he improved from E8/B4 to A2/A1 respectively….Desmond truly cares, and his one-on-one sessions were not cheap but they were worth it. Mya and Jiarong also helped a lot with Chemistry and Physics to a B3 from a fail. It wasn’t just about academics…..their guidance really boosted his confidence and mindset too.”

Failing → A1 in Sec 2 Math

“In Sec 1, my son struggled with the subject, he failed two WAs and only managed a borderline pass in his EOY exam. Since engaging Desmond at the start of Sec 2, we have seen significant improvement. In the recent WA1, my son improved drastically from failing grades to A1. Desmond is patient and able to explain concepts clearly, which has boosted my son’s confidence in Math.”

Ai Shin Ng Parent · Google review, 2026

★★★★★

C → A in Sec 2 Math

“When Ava was in Sec 1, Math was one of the subjects she struggled with, and she finished with a C grade. With the patience, encouragement and guidance from her teacher at Kahu Learning, we gradually saw a real change — not only in her understanding of Math, but also in her confidence. Now in Sec 2, she has achieved an A for Math!”

Angela Goh Parent · Google review, 2026

★★★★★

F9 → A2 in Math

“Desmond is a good tutor. With his help and teaching experience,my daughter, has improved from F9 to A2. It was a big jump bench mark of her results. Luckily, we made the right choice for engaging him as her tutor. A very big thump up to him. His teaching method really works on my girl as she understands better than what the teacher taught in school.”

Eileen Ang Parent · Google review, 2025

★★★★★

D7 → A2 in Sec 1 Science

“Teacher Nimai is a very patient and diligent teacher who never fails to follow up with my son on his homework. He also helped adjusted his own timing to avoid clashing with my son's CCA which I deeply appreciate. Under the guidance of teacher Nimai my son's Sec 1 Science went from D7 to A2 in 6 months. Thank you for all your efforts!”
