What online secondary math tuition with DeepThink covers
We follow the MOE Secondary Mathematics syllabus across Sec 1 to Sec 4, with weekly live classes matched to your child’s level and stream — G1, G2, G3, or IP. Every lesson is taught by a Singapore math teacher; targeted online practice between lessons reinforces the same week’s topic.
Sec 1 and Sec 2 — Lower Secondary foundations
Algebra — expressions, equations, simultaneous equations, quadratic introduction
Geometry — angles, triangles, polygons, congruence, similarity, Pythagoras
Number — primes, indices, ratio, percentage, rate, speed
Statistics and probability — basic data interpretation
Sec 3 and Sec 4 — Upper Secondary depth
E-Math — algebra, coordinate geometry, trigonometry, mensuration, statistics
A-Math — polynomials, calculus, trigonometric identities, vectors, exponential and logarithmic functions
Combined exam-style problem solving across multiple topics
Full-paper timed practice in the months before O-Level / SEC
Stream-specific support
G1 (former N(T)) — paced foundational work with practical problem-solving emphasis
G2 (former N(A)) — standard syllabus with structured progression
G3 (former Express) — full O-Level / SEC syllabus including A-Math
IP — adapted to each school’s scheme of work, often beyond standard G3 pace
Current Sec 1–3 students will sit the Singapore-Cambridge SEC in place of O-Level / N(A)-Level / N(T)-Level. The content and skills required remain similar; G1, G2, and G3 align to the former N(T), N(A), and O-Level standards respectively.
Why secondary math is the year parents notice the cracks
When parents reach out to us mid-secondary, the same patterns surface — and they rarely go away on their own.
The Sec 1 jump from primary feels bigger than expected
The transition from primary arithmetic to secondary algebra catches many previously strong students off guard. Variables, formal equations, and proof-style reasoning are different skills than PSLE word problems, and Sec 1 is when the gap shows.
School topical tests look fine but exams do not
Topical tests at school cover one chapter at a time. Real exams combine concepts across topics. Many secondary students discover in mocks that they cannot integrate ideas under timed conditions — and the deeper the year, the harder the gap is to close.
Stream changes are happening with too little visibility
Subject-Based Banding lets students move between G1, G2, and G3, but parents often only learn after the fact whether their child is on the right level. Without weekly visibility, the chance to fix a borderline placement is easy to miss.
IP schools run their own pace and standard textbooks do not match
IP schools use custom materials and non-standard pacing. Generic tuition that follows a textbook often does not align with the school’s scheme of work, which means the lesson and the school week are pulling in different directions.
How DeepThink runs online secondary math tuition
Secondary tuition at DeepThink combines weekly live teaching with targeted practice that adapts to your child’s stream and the year they are in.
Weekly 1.5-hour live class with a Singapore math teacher
Small live online groups taught by an experienced teacher, matched to your child’s level — G1, G2, G3, or IP. The teacher walks through the topic, works through examples, and adjusts pacing based on what the class is finding hard.
Targeted practice between lessons with instant marking
Between live classes, students work through practice matched to that week’s topic. Every wrong answer comes with a worked solution — sign errors, missed steps, or wrong methods get caught immediately rather than reinforced.
Stream-aware teaching, including IP
For IP students, lessons adapt to your school’s scheme of work and assessment calendar. For G1, G2, and G3 students, the focus and pacing match the SEC level your child is heading into — not a generic Sec syllabus.
Visibility for parents — and one simple price
You see which topics are secure, which need more work, and what your child should focus on this week. S$30 per live class is the same fee whether the lesson is Sec 1 G1 or Sec 4 IP A-Math.
The result: secondary students get a teacher who actually knows their stream and visibility for parents — without a weekday commute eating into homework time.

When online secondary tuition is the right fit
When online secondary math tuition makes sense for your family
These are the situations where parents tell us the switch made the biggest difference during the secondary years.
Your child is in IP and the school’s pace does not match generic tuition
Standard tuition centres often follow a generic textbook, not your child’s IP scheme of work. Online tuition that adapts to school materials means the lesson and the school week are pulling in the same direction.
Your child is on a stream borderline and you want visibility
If your child is between G2 and G3, or considering A-Math eligibility, weekly visibility into which topics are secure helps you make the stream call with evidence rather than guesswork.
Weekday evenings are too short for in-person tuition
A secondary student leaving school at 4 pm and travelling to a tuition centre often arrives drained. Online removes the commute so the lesson starts when your child still has the focus to learn.
If any of these patterns sound familiar, online secondary math tuition is probably the right fit — a free trial class is a low-friction way to see whether DeepThink is the right version of it for your family.
Frequently asked questions
Clear answers for parents
Does DeepThink cover G1, G2, G3, and IP secondary math online?
Yes. We cover all four pathways across Sec 1 to Sec 4. Lessons are matched to your child’s stream — G1 (former N(T) standard), G2 (former N(A) standard), G3 (former O-Level standard), or IP. The same flat S$30 per class fee applies across every stream and year.
How does an online secondary math class with DeepThink actually run?
Each week, your child joins a 1.5-hour live class taught by a Singapore math teacher. The teacher works through the week’s topic at the level matched to your child’s stream, walks the class through worked examples, and answers questions in real time. Between classes, students complete targeted online practice with instant marking and worked solutions. Parents see what was covered and where their child stands.
Will my IP child’s school syllabus actually be supported?
Yes. IP schools use custom materials and non-standard pacing, and we adapt to each school’s scheme of work rather than following a generic textbook. Students bring their school materials and assessments, and we align support to their specific programme — including topics introduced earlier than the mainstream G3 timeline.
Is online math tuition effective for secondary students?
Yes, when the lesson is live, taught by an experienced teacher, and supported by structured practice between sessions. The mode (online vs in-person) matters far less than whether the teaching is responsive, the practice is targeted, and parents have visibility. Online removes the commute so a school-evening lesson starts when your teenager is still able to focus.
My child is on a stream borderline — can DeepThink help with the move?
Yes. Stream movement under Subject-Based Banding depends on sustained school performance, and consistent weekly support is one of the most reliable ways to demonstrate that. We help borderline students close the gap between their current stream and the next, and we give parents weekly visibility so the stream conversation is informed.
How much does online secondary math tuition cost in Singapore?
DeepThink charges a flat S$30 per 1.5-hour live class across every secondary stream and year, with targeted online practice included. Premium in-person centres in Singapore often charge S$70 to S$130 per hour for secondary tuition; freelance tutors found through matchmaking platforms typically range from S$45 to S$90 per hour.
Will my secondary-school child stay focused for an online class?
For most students, yes — and often more than at an in-person centre after a long school day, because the class starts when they are still able to focus rather than after a 30 to 45-minute commute. Classes are small and live, so the teacher checks in on attention the same way they would in person. We also publish a guide on observable signs of attention versus disengagement during online tuition for parents who want to monitor it directly.
How do I know my child is making real progress, not just attending classes?
Parents have visibility into which topics are secure, which need more work, and what their child should focus on this week. We surface persistent gaps early — well before exams — and tell you specifically what we are doing about them. The goal is that you do not wait until a school report to know whether the tuition is working.
