The most useful trial lesson has a narrow target. Choose two sticking points, bring the work where they showed up, and decide how you will know the hour helped.
This page shows how to find your two points, how to turn them into a plan, and what a good focus looks like for Cambridge IGCSE Physics.
Why does a narrow focus work better?
Physics is connected. A single habit, such as picking a formula before sketching the situation, can cost marks in motion, pressure, electricity and waves. An hour spent on that habit repays itself many times, while an hour spent skimming five topics gives you a pleasant feeling and no change in your answers.
A narrow focus also makes the trial easier to judge. You can tell at the end whether the teacher explained the point clearly, whether you could do a similar question yourself, and whether you know what to practise next.
How do I find my two sticking points?
Use your marked work, not your impressions. Here is a worked example with an error log from three returned questions.
| Question | What I wrote | What went wrong |
|---|---|---|
| A 2 kW heater runs for 30 minutes. Energy in joules? | 2000 × 30 = 60 000 J | Used minutes, not seconds |
| Speed-time graph: find the distance | Gradient = 3 | Needed the area, used the gradient |
| Explain why the trolley slows down | “Friction” | Did not say friction acts opposite to motion |
Sorting the causes. Line one is a unit conversion. Line two is a graph-feature choice. Line three is a missing direction in a force explanation. Line one and line three look unrelated, but in both cases the student wrote something without a check on meaning. Two patterns emerge.
- Pattern A: choosing and checking units and graph features (lines one and two).
- Pattern B: explaining forces with direction and cause (line three).
Checking the first line properly. The correct working is 2 kW = 2000 W and 30 min = 1800 s. Energy = power × time = 2000 × 1800 = 3 600 000 J, which is 3.6 MJ. That is also 1 kWh, since 2 kW × 0.5 h = 1 kWh and 1 kWh = 3.6 MJ. The student’s 60 000 J was 60 times too small, and the unit would have shown it.
Those two patterns become the two sticking points for the trial. The related guides are unit conversion in electrical energy, gradient versus area on a graph and describing forces with direction.
Which focus fits which symptom?
| What you notice | A useful focus | Bring to the lesson |
|---|---|---|
| Wrong or missing units, wrong conversions | Carrying and checking units on every line | Two marked calculations with unit errors |
| Choosing the wrong formula | Sketch first, then choose the relationship | A question you started, then abandoned |
| Mixing up graph features | What gradient, intercept and area mean on each graph | Graph questions from motion and graphs |
| Forces with no direction | Resultant force and direction in words | Questions from forces and momentum |
| Explanations marked down | Writing a cause-and-effect chain from a diagram | A marked written answer |
| Stuck on circuits | Series, parallel and reading circuit graphs | Circuit questions from potential difference, resistance and circuits |
| Practical skills feel weak | Planning, graphing and concluding from data | Your own notes from physics investigations and explanations |
If none of these fits, name the topic, for example “thermal processes and heat calculations”, and bring two questions from it.
How do I turn the two points into a one-hour plan?
The one-hour trial agenda builder creates an editable agenda on your own device. A simple shape works well.
- Minutes 0 to 5: tell the teacher your two sticking points and show one piece of marked work.
- Minutes 5 to 25: work the first sticking point on a question you could not finish. Think aloud.
- Minutes 25 to 45: work the second, or try a fresh question on the first without help.
- Minutes 45 to 60: agree what you will practise next, and ask any questions about how the lessons could continue.
The teacher may adjust the plan, and that is a good sign if they explain why.
What should I bring, and what should I do afterwards?
Bring:
- Two or three marked pieces of work, or practice questions you could not finish.
- Your error log, even if it has only a few lines.
- A calculator allowed in your exam, paper and a pen.
- Your syllabus and exam year, confirmed with your school or exam centre. The 0625 guide lists what to check.
Afterwards, use the post-trial reflection guide. It asks three separate questions: did I understand, could we communicate, and is the next step clear?
Discuss anything unclear directly with the teacher. Ongoing lessons, fees and schedule are agreed with them, not through this website.
Where does this fit in the bigger picture?
If you are not yet sure tuition is what you need, start with considering Physics tuition and its short self-test. When you are ready, the Physics tuition page explains enquiry, teacher assignment and the paid one-hour trial, starting from RM80 at the assigned teacher’s confirmed rate. The Physics learning guide gives you the topic map for choosing what to practise in between.
