A Math Tuition.

A Math is what separates the As at O-Level. Built from first principles — algebra fluency, calculus, trig identities. Real, measurable improvement is the goal.

If this sounds familiar

Chain rule's inner derivative is the most-dropped step in A Math.

Differentiate sin(3x²). Your child writes cos(3x²). The 6x is missing. Two marks lost. Repeat across five calculus questions and the paper bleeds 10 marks before the integration even starts. The function is right. The structure is right. The inner derivative just — vanishes.

"I forgot to differentiate the bracket inside. I do this every single time."

We drill the chain rule from first principles — outer-then-inner, written out as two visible steps, never collapsed in one line until the habit's automatic. Then weekly mixed-derivative speed sets where the inner-derivative check is the first thing they self-mark. It's the single highest-yield fix in A Math.

How we teach it

Methodology.

The methods we teach with — applied across the term, calibrated to where each student needs them most.

01
First-principles teaching
We don't show students 'the formula' — we show why it works. Calculus students who know why the chain rule exists make far fewer errors than those who memorised the rule.
02
Trig identity automation
R-formula, double-angle, Pythagorean identities — drilled by sight. Most A Math trig questions are solved within 20 seconds once the right identity is recognised.
03
Timed practice · teacher-initiated
Real exam-format timed practice — teacher-initiated for students who need extra exam-condition rehearsal.
04
Common-mistake bank
Tracked per-student. Topics where you wobble get scheduled back in deliberately.
05
Small classes (max 10)
A Math demands attention — we keep classes small enough that the teacher can work the room properly.
06
Calibrated to the class
Pacing, examples and topic emphasis are tuned to the cohort in front of us. Every A Math class arrives with a different mix of strengths, gaps and pace — so each session pulls its weight rather than running from a fixed script.
07
Every WA tracked & teacher-monitored
Weekly Assignment results are logged against each student by topic, by question type, by week. Teachers review trajectories weekly — not at term-end — so wobbles get scheduled back in deliberately, before they harden into prelim losses.
Where students lose marks

Common pitfalls
& how we fix them.

Most lost marks are habit, not knowledge. We track them, name them, and drill them out.

!
Chain rule — forgetting the inner derivative
d/dx[sin(2x)] = cos(2x) (wrong, missing the ×2 from the inner derivative); should be 2cos(2x). The most common A Math calculus slip — and it propagates through product rule, quotient rule, and implicit differentiation. Loses 3-5 marks on full-mark differentiation questions. Fix: a fixed working format that separates outer and inner functions before differentiation — students write "u = 2x, du/dx = 2" then apply the chain — drilled until the inner derivative is impossible to forget.
!
Integration — missing the constant +C
∫2x dx = x². Should be x² + C. Skipping the constant looks harmless until kinematics — where C is the initial position — and every subsequent calculation cascades wrong, losing 3-4 marks on the whole question. Fix: every indefinite integral written with "+ C" as a fixed checkbox item, and C evaluated explicitly whenever initial conditions are given. Drilled on weekly integration sets with deliberate "find C" prompts so the constant is never forgotten.
!
Discriminant — real vs equal vs no real roots
Δ = b² – 4ac. Students write "Δ ≥ 0 for real roots" when the question asks for "two distinct real roots" (which is Δ > 0, strict). One-mark distinction, but it appears on most A Math papers as the gateway question to a whole proof, so the cascade costs 3-4 marks. Fix: a flowchart drilled into every quadratic-roots problem — Δ > 0 → two distinct; Δ = 0 → repeated; Δ < 0 → none — with the inequality sign matched to the wording.
!
Trig identity choice — picking the wrong starting identity
"Prove tan²x + 1 = sec²x." Student starts with sin²x + cos²x = 1, manipulates for five minutes, gets nowhere, and abandons the proof. Right identity, wrong path. Costs 4-5 marks on every trig-proof question, and Paper 2 always has one. Fix: a decision tree drilled on the first five trig proofs of the year — left side has tan/sec? Start with a tan identity. Pure sin/cos? Start with sin²+cos²=1. Identity chosen before the pen moves.
!
Modulus equations — forgetting the second case
|2x – 3| = 5 has two cases: 2x – 3 = 5 (giving x = 4) and 2x – 3 = –5 (giving x = –1). Students solve only the positive case — half the marks gone. The same slip applies to modulus inequalities, where missing the negative case wipes the solution set. Fix: a two-case layout drilled into every modulus question — "Case 1: …" and "Case 2: …" written end-to-end before any final answer. Worked counter-examples weekly until both cases are reflex.
Sample technique

Why most students lose marks on stationary points.

A typical question: "Find the stationary points of f(x) and determine their nature." Students typically differentiate, set f'(x) = 0, find x, and stop. They've earned 4 of the 6 marks. The remaining 2 are for nature — using the second derivative or the first-derivative test. We teach both methods and a fixed working format that forces both steps. Two extra marks per question, every time.

Inside the lesson

"I only joined a few months before my O-level A-math exam but managed to jump 4 grades thanks to Ms Michelle. Her friendly and patient approach enabled me to grasp complicated math concepts with ease, allowing me to do well in a subject I had previously struggled to pass."

FAQ

Common questions.

Is A Math really harder than E Math?
Yes — but mostly because it builds on Sec 1–2 algebra that's often shaky, and adds calculus. Once those are fixed, A Math is reliable, and most students see meaningful improvement by prelims.
My child took A Math at Sec 3 and is failing — too late?
No. Sec 4 students who join early have seen meaningful improvements within a year — but it requires consistent homework and teacher-initiated timed practice.
Is your A Math tuition aligned to the latest syllabus?
Yes — refreshed yearly against SEAB exam reports.
Do you teach calculus from first principles?
Yes. Differentiation by first principles is taught explicitly — not just 'the formula' — so when chain rule and applications come up later, students know why each rule works.
Can my child take A Math without E Math at Genie?
Most students take both — schedules pair them on the same day. You can take just A Math if you prefer.
How big are the classes?
Max 10. Most A Math sections sit at 5–8.
What time slots do you offer?
Weekday evenings and Saturday daytime, at both Bukit Batok and Yishun. WhatsApp us your preferred day/time and we'll come back with live availability.
Where is your nearest A Math centre to Bukit Gombak?

Where is your Yishun A Math centre?
417 Yishun Ave 11 #01-339 — a short bus ride from Khatib or Yishun MRT. Yishun branch
How do I book a free A Math trial?
WhatsApp 9181 7689 — we'll confirm the next slot.
Can my child catch up if they join mid-term?
Yes — we can arrange short 1-to-1 bridging sessions to fast-track new joiners up to where the current class is. Most students catch up in 2–3 sessions, then slot into the regular class without falling behind.
