Learning Guide

This guide explains how to study each module effectively, how to maintain an error log, and how to plan your revision across the eight-week course.

How to Prepare for Each Module

Before opening a module page, spend five minutes on self-preparation:

  1. Recall the prerequisites. Ask yourself: what did the previous module cover? Can I recall the key formula or definition without looking?
  2. Attempt the diagnostic questions cold. The Diagnostic Activity at the top of each module is designed to surface gaps — attempt it before reading any theory.
  3. Write your prediction for the Opening Problem. The Opening Problem introduces the module’s central concept through a real scenario; forming a prediction (even a wrong one) primes your attention.

Prerequisites by module

Module Prerequisites to review
1 — Numerical calculations Basic arithmetic; fractions
2 — Algebra and equations Module 1: percentages and index numbers
3 — Graphs and systems Module 2: first-degree equations
4 — Sequences Module 1: powers and percentages
5 — Financial mathematics Module 4: arithmetic and geometric sequences
6 — Functions Module 2: algebra; Module 1: powers
7 — Derivatives and optimisation Module 6: quadratic functions
8 — Revision Modules 1–7

Error Log

An error log is a personal record of every mistake you make during exercises, quizzes, and practice exams. Reviewing it before assessments is one of the most efficient revision strategies.

What to record

Use this template for each error:

Field What to write
Error Copy the incorrect working exactly as you wrote it.
Root cause Name the underlying reason: wrong formula, wrong method, arithmetic slip, sign error, incorrect reference value, domain error, etc.
Correct method Write the correct step-by-step solution.
Prevention rule Write one rule or check you will apply next time.

Example:

Field Entry
Error \(\Delta\% = (100 - 80)/100 \times 100 = 20\%\)
Root cause Divided by the final value instead of the initial value.
Correct method \(\Delta\% = (100 - 80)/80 \times 100 = 25\%\). The initial value is always the reference base.
Prevention rule Before computing, circle the initial value and label it “denominator”.

When to update the log

  • Immediately after completing a Guided Practice or Check Your Understanding section.
  • After each practice exam or timed exercise.
  • After receiving corrected assessments.

How to use the log before exams

  • One week before: read through every entry; highlight those you are still unsure about.
  • Two days before: attempt a fresh exercise for each highlighted error; can you now avoid it?
  • The night before: read only the prevention rules — do not rework problems.

Revision Schedule

This schedule assumes the course meets once per week over eight weeks, with the final exam in week 11 or 12.

Eight-week course schedule

8 Module 8 Mixed revision Attempt all 8 challenge problems; practice exam

Two-week consolidation block (before the final exam)

Week 9 — Formula sheet and error-log review

  • Day 1–2: Read the formula sheet from cover to cover. For each formula, can you state what it computes and give one example of its use?
  • Day 3–4: Read your error log. Attempt a fresh exercise for each highlighted error category.
  • Day 5–6: Work through the Check Your Understanding questions for every module without notes. Record new errors.
  • Day 7: Rest.

Week 10 — Timed practice exam

  • Day 1: Attempt the practice exam from Module 8 under exam conditions (no notes, no formula sheet, 90 minutes).
  • Day 2: Correct and record all errors in the log.
  • Day 3–4: Review only the topics where errors appeared.
  • Day 5: Final read-through of prevention rules in the error log.
  • Day 6: Rest and prepare materials.
  • Day 7 (or exam day): Exam.

Tips for exam day

  1. Read each problem fully before writing anything. Identify the mathematical structure (linear? quadratic? geometric?) and the method before applying any formula.
  2. Show all steps, even if the calculation seems obvious. Partial credit is awarded for correct method even if arithmetic is wrong.
  3. Check the sign of \(a\) before declaring a maximum or minimum for a quadratic optimisation.
  4. Verify your answer in context: a negative quantity, an impossibly large interest rate, or a cost below zero signals a method error.
  5. Use the formula sheet (if provided) systematically: scan all formulas relevant to the topic before choosing one.
