How Paper 01 is built, how its 45 items spread over the four sections, techniques for checking answers by substitution, estimation and elimination, and a timed 45-item mock exam.
Papers 1, 2 and 3Paper 01≈ 30 min
Before you start
By the end of this lesson you can…
describe the structure, timing and mark conversion of Paper 01
use the item blueprint to plan revision
use substitution, estimation, elimination and graph-reading to check answers
sit a timed 45-item mock and use the results to plan revision
5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
LESSON E1 · EXPLAINER
Paper 1: Multiple-Choice Strategy
45 questions, 90 minutes, a calculator allowed. Many answers can be tested by plugging the options back in — if you know when to do it.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Step 2 · Read
Key notes
Copy these into your notebook in your own words — that is how they stick.
Structure
45 items, 45 marks weighted to 60; 1 h 30 min; 30% of the grade.
Non-programmable calculator allowed in Papers 01, 02 and 032.
Method
Read → work → check → eliminate → shade.
Checks
Substitute options; test x = 0, 1; differentiate to check integrals.
Timing
≈ 2 min per item; skip and return.
Guessing
Answer every item.
Revision
Follow the blueprint: trig 9, calculus 10, quadratics 4.
EXAM TIPS & COMMON MISTAKES
If an integral is the stem, differentiate the options — often quicker than integrating.
In trig items test a special angle in both the stem and each option.
Calculator in radian mode for calculus and radian items — check before the exam.
Mark the questions you skip so you can find them again.
Step 3 · Practise
Paper 1 practice — multiple choice
8 items modelled on real CSEC Paper 1 questions. Choose one answer for each, then check. Aim for 80% or better. Work each item on paper first.
