What to Focus & How to Prepare?
Complete syllabus breakdown, question-bank frequency analysis, difficulty rankings, solved sample problems and a 10-week study plan. Master the 5 physics questions in 10 minutes.
Physics is the last and shortest section of CEnT-S: only 5 questions in 10 minutes. Questions test basic relations — proportionality, units and graph reading — rather than long numerical solutions.
Because it is only 5 points, study physics efficiently: mechanics alone accounts for most of the questions, and dimensional analysis/proportional reasoning unlocks the rest.
Which topics demand your deepest attention? Below is the topic breakdown from our CEnT-S question data:
| Topic | Total | |
|---|---|---|
| Kinematics & Dynamics | 17 | |
| Electricity & Energy Use | 4 | |
| Thermodynamics & Temperature | 3 | |
| Optics & Light | 2 | |
| Quantities, Units & Measurement | 1 | |
| Oscillations | 1 | |
| Waves & Sound | 1 | |
| Simple Machines & Levers | 1 |
*Question counts per topic in 6 CEnT-S past exams from our question bank; each exam has the full 5 Physics questions. Exams are numbered, not dated. These figures are derived from the past-exam question samples that have reached us; the samples may be incomplete or contain errors, and the topic mix can change from one exam session to the next. Treat them as a guide to priorities, not a prediction of your exam.
Not all topics require the same time investment. Some need extensive problem-solving practice, others rely on precise conceptual recall:

Take Diagnostic TestA topic-by-topic look at the Physics section of the official CISIA CEnT-S syllabus:
How it appears on CEnT-S: Dimensional analysis (‘what are the units of Q?’) and percentage change under a power law.
How it appears on CEnT-S: Reading v–t graphs and vertical-throw problems with g = 10 m/s².
How it appears on CEnT-S: Energy conservation shortcuts instead of kinematics; forces on inclined planes and levers.
How it appears on CEnT-S: Celsius ↔ Kelvin conversions, buoyancy and hydrostatic pressure.
How it appears on CEnT-S: Energy-bill style questions (kW × h) and how resistance scales with wire length and diameter.

cisiaonline.it — CEnT-S structure and syllabusSee how CEnT-S physics questions are built and how disciplined elimination avoids the −0.25 penalty:
Recurring conceptual and tactical errors that cost students crucial points:
Intensity, gravity and Coulomb force go as 1/r²; kinetic energy as v². Check the exponent before computing a percentage.
kW is power, kWh is energy. Options with the wrong unit can be eliminated instantly.
In vertical motion choose a positive direction and keep it; mixing signs gives the planted wrong heights.
Absolute temperature in gas laws and thermodynamics must be in kelvin.
10 minutes for 5 questions: if a problem needs more than 3 lines, look for a ratio or energy shortcut.
Take a timed diagnostic; rebuild the Foundation topics marked ‘Easy’ and note every error type.
Work through the ‘Medium’ and ‘Hard’ topics in the order of the frequency table; 20–30 targeted questions per topic.
Mixed sets under section timing (2 min/question). Keep an error log: concept, reading or calculation.
One full 65-question CEnT-S mock per week with real section timers; review every wrong and every guessed answer.
Re-do your error log, revise traps, and practise the skip-or-guess rule for the −0.25 penalty.
