Step 1 · Watch

Explainer video

6 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

60 questions, 90 minutes, one mark each. Here is how to collect every mark you know — and a few you did not think you knew.

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

60 items; 20 per module; 1 h 30 min; 1 mark each; 30% of the grade.

Blueprint

M1: 4, 4, 3, 4, 2, 3. M2: 4 each on five topics. M3: 6, 6, 4, 4.

Method

Read → estimate → calculate → eliminate/substitute → check.

Estimate

Round to 1 significant figure to check the size of an answer.

Substitute

For equations, try the four options in the equation.

Traps

NOT/LEAST/EXCEPT; units; distractors from wrong formulae; percentage of the original.

Timing

About 1 minute per item first pass; leave time to check shading.

Guessing

No penalty — answer every item.

EXAM TIPS & COMMON MISTAKES

  • Underline the units in the stem before you start calculating.
  • Write on the question paper: calculations, diagrams, crossings-out. It is allowed, and it reduces slips.
  • If two options remain, check which one satisfies a different condition in the stem.
  • Use the formula list at the front of the paper — you do not need to memorise every area and volume formula, but you do need to know which to use.
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.
