Updated November 2026. These KCSE 2026 Physics Paper 3 (Practical) (232/3) predicted questions are built from past-paper trends: we ranked the topics that past KCSE Physics Paper 3 papers test most often, then wrote original practice questions on them. They are not leaked, official or guaranteed questions, and this site is not linked to KNEC or KICD. Use them to practise the areas most likely to appear, alongside your full syllabus revision.
KCSE Physics 232/3 prediction: most commonly tested topics
The ranking below comes from the topic coverage of past KCSE papers, as summarised in our paper guides. It is a ranking, not an exact count: exam papers change every year.
| Rank | Topic | How it is usually tested |
|---|---|---|
| 1 | Electricity experiment | Recording voltmeter and ammeter readings, plotting V against I, finding resistance or e.m.f. |
| 2 | Lenses or optics experiment | Object and image distances, finding focal length from a graph |
| 3 | Mechanics experiment | Pendulum, spring extension or moments, with a graph and gradient |
| 4 | Graph work and gradients | Scale, plotting, line of best fit, gradient and intercept |
Free sample: 3 KCSE 2026 Physics Paper 3 predicted questions
Q1. You plot V (y-axis) against I (x-axis) for a resistor and get a straight line through the origin with gradient 4. What is the resistance?
Marking scheme
R = gradient = 4 Ω.
Q2. Explain how to find the gradient of a straight-line graph accurately.
Marking scheme
Choose two points far apart on the line (not data points), and use (y₂ − y₁)/(x₂ − x₁), with units.
Q3. A pendulum makes 20 oscillations in 40 s. Find the period.
Marking scheme
T = 40/20 = 2 s.

Frequently asked questions
Are these the real KCSE 2026 Physics Paper 3 (Practical) questions?
No. Nobody outside KNEC knows the real questions, and any site claiming a leak is lying or breaking the law. These are original practice questions written by the CBC Guide team, predicted from the topics past KCSE papers test most often.
Which topics come up most in KCSE Physics Paper 3 (Practical) (232/3)?
The most commonly tested areas in past papers are Electricity experiment, Lenses or optics experiment, Mechanics experiment, Graph work and gradients. The full ranked list is in the table above.
How do I get the full set of predicted questions?
The first 3 questions are free. The remaining 15, each with a marking scheme, unlock with the KSh 20 Day Pass or the KSh 500 Monthly Pass, paid by M-Pesa. The passes do not auto-renew.
How should I use predicted questions in the last days before the exam?
Answer each question under time, mark it with the scheme, then go back to your notes for any topic you got wrong. Do not skip topics that are not on this list, because KNEC can test any part of the syllabus.
