E-Math Exam Techniques Bukit Timah
Key takeaways
- Know the exam’s format and timing cold (Paper 1 & 2 are 2 h 15 min, 90 marks each; calculators allowed). Use ~1.5 min/mark pacing and finish with a 10–15 min buffer. (SEAB)
- Build retention with retrieval practice + spaced and interleaved review; they beat re-reading and cramming. (psychologicalscience.org)
- Fix accuracy losses with an error journal, worked→faded examples, and a calculator routine tailored to E-Math question types.

Know the E-Math exam (format, timing, AOs)
- Two papers: Paper 1 (2 h 15 min, ~26 short-answer Qs, 90 marks) and Paper 2 (2 h 15 min, 9–10 longer Qs, 90 marks). All questions compulsory; approved calculators allowed in both papers. The final Paper-2 question focuses on real-world application. (SEAB)
- Assessment Objectives weightings roughly AO1 45% (standard techniques), AO2 40% (problem-solving), AO3 15% (reason/communicate). Train all three, not just procedures. (SEAB)

Time management blueprint (1.5 min/mark)
With 135 minutes for 90 marks, you get ~1.5 minutes per mark. Build your plan around that ratio.
Paper 1 (short answers)
- Sweep 1 (45–50 min): Secure all 1–3 mark items; skip time-sinks after 90 seconds.
- Sweep 2 (45–50 min): Return to 3–4 mark items and any skipped questions.
- Buffer (10–15 min): Units, rounding (3 s.f. unless stated), and transcribed values. (SEAB)
Paper 2 (longer items)
- Start with your strongest topics (method selection matters).
- For the final real-world task, leave ~20 minutes to set up variables, assumptions, and checks. (SEAB)

9 techniques that actually boost marks
These are high-utility, evidence-based, and easy to run at home or in class.
- Retrieval practice (mini-quizzes, oral teach-backs)
Actively recalling beats re-reading for long-term retention—the testing effect. Use 2× weekly 10–12 Q mixed quizzes; log misses. (psychologicalscience.org) - Spaced practice (no cramming)
Revisit topics on an expanding schedule (e.g., Day 1 → 3 → 7 → 14). Works across ages and materials. (psychologicalscience.org) - Interleaving (mix problem types)
Alternate algebra/geometry/statistics in warm-ups so students choose methods, not just apply the last chapter. Strong math-specific evidence. (gwern.net) - Worked → Faded examples
Study a complete solution, then remove steps the student fills in—lighter cognitive load, faster generalisation. - Error journal
Track the first wrong step (signs, rearrangement, units, misread). Review weekly. This converts mistakes into memory. - Calculator fluency for E-Math
Pre-program sequences you’ll reuse (e.g., stats mode for mean/SD; trig with degree mode). Calculators are allowed in both papers, so use them efficiently and accurately. (SEAB) - Goal-directed drills
10–20 min “rojak sets” before longer study: 3 topics × 3 marks each. Timed to the 1.5 min/mark rule. - Formative checks
One 10-min “exit ticket” each week to decide what to re-teach now. (Parents can run this at home; tutors in class.) - Reflect & explain
End sessions with “What type was this? Why this method first?”—a metacognitive nudge that cements method selection.
For parent-ready coaching language and examples, use our Parent’s Complete Guide.
Avoid these common mistakes (and how to prevent them)
- Rounding & accuracy: Unless specified, give non-exact numerical answers to 3 s.f.; angles to 1 d.p. Note this in your final check routine. (SEAB)
- Missing working: SEAB notes that omission of essential working loses marks—write the method, not just the answer. (SEAB)
- Units & mode: Wrong units (cm² vs cm³) and incorrect calculator modes (rad/deg) are silent killers.
- Method fixation: Students keep using the last technique they studied; fight this with interleaving. (gwern.net)

Using past papers & mocks the smart way
Sequence
- Topic repair (worked→faded examples)
- Short interleaved sets (10–20 min)
- Full timed papers with the 1.5 min/mark pacing
- Post-mortem: capture the first wrong step + update error journal
Set up one mock every 2–3 weeks; escalate to weekly in the final month. See how we run it in 3-pax classes: E-Math Tuition Bukit Timah.
12-week exam-ready plan
Weeks 12–9: Rebuild weak strands (algebraic manipulation, trig, graphs). 2× retrieval sets/week + 1× interleaved warm-up.
Weeks 8–5: Add full Paper-1 style sets (60–75 min), error-journal reviews, and one Paper-2 long question weekly.
Weeks 4–2: Alternate full Paper-1 and full Paper-2 under time; run one real-world Paper-2 end question each week.
Week 1: Two mocks + light topic top-ups; prioritise sleep and routine.

FAQ for parents & students
How much time should I spend on E-Math daily?
Aim 45–60 minutes on weekdays in Term 3/4: a 10–15 min interleaved warm-up, 20–30 min targeted practice, 10–15 min review.
Is re-reading my notes enough?
No. Retrieval and spacing reliably beat re-reading for long-term memory—use mini-quizzes and revisit intervals. (psychologicalscience.org)
Should I practise by chapters or mixed sets?
Do both. Learn new ideas in short blocked bursts, then consolidate with interleaving so you can pick the right method under pressure. (gwern.net)
What’s different about E-Math vs A-Math exam skills?
E-Math emphasises broad application across three strands; A-Math adds algebraic depth and calculus. See our comparison and A-Math tips: E-Math vs A-Math and From Fail to Distinction. (Bukit Timah Tutor)
