How to Get an A* in IGCSE Physics

An A* strategy needs current syllabus coverage, targeted practice, timed components and correction of repeated errors. Use this guide beside marked work so each decision is based on evidence rather than a fixed paper count or timetable.

For the 2026 to 2028 syllabus, Extended candidates take Paper 2, Paper 4 and either Paper 5 or Paper 6. Extended is eligible for grades A* to G. Core is capped at grade C.

What does A* preparation actually require?

A strong plan combines five systems:

1. complete and current syllabus coverage
2. accurate recall and use of equations, units and definitions
3. original topical practice to repair specific weaknesses
4. timed preparation for all three components
5. detailed marking, correction and delayed retry

The grade is an outcome of those systems. It should not be promised by a paper count, timetable or tutor.

Step 1: Audit every current syllabus outcome

Use the current Cambridge IGCSE Physics 0625 syllabus rather than an older formula sheet or revision checklist.

Mark each outcome as:

• Red: not taught, forgotten or repeatedly incorrect
• Amber: understood with prompts or only in familiar questions
• Green: answered independently in mixed questions

Keep Core and Supplement requirements separate. Current-cycle examples that are commonly mislabelled include:

• Celsius-to-kelvin conversion is Core
• the transformer voltage-turns relationship is Core
• efficiency calculations are Supplement
• $pV = \text{constant}$ is Supplement
• basic redshift and expanding-Universe evidence are Core
• fission and fusion are Supplement
• a specific latent heat equation is not part of the current 2026 to 2028 syllabus

A student cannot prepare reliably for A* while using a syllabus map that includes removed content or hides required outcomes.

Step 2: Learn equations with meaning and conditions

Do not memorise symbols without knowing:

• the quantities represented
• the required units
• the tier
• the conditions under which the equation applies
• the expected size and direction of the answer

A useful recall drill is:

1. write the relationship in words
2. write the symbols
3. state every unit
4. rearrange for each variable
5. complete one original question
6. classify any error as recall, equation choice, algebra, units or checking

Use the current equations list. It is mapped to the 2026 to 2028 syllabus and excludes removed formulas.

Step 3: Practise one weakness before using another full paper

A complete paper is a diagnostic and performance test. It is not always the most efficient way to repair one specific issue.

After identifying a weakness, use a short progression:

1. direct recall or definition
2. one-step application
3. rearranged calculation or linked explanation
4. graph, diagram or practical context
5. mixed question with another topic
6. timed question without prompts

The original topic question bank can be filtered by topic, tier, skill and difficulty. The questions are original and include worked marking points rather than copied Cambridge paper text.

Step 4: Mark every lost mark by cause

A total score does not explain what to do next. Classify each lost mark.

Count repeated categories across several papers. The most frequent repeatable error should influence the next week of revision.

Step 5: Prepare Paper 2 deliberately

Paper 2 contains 40 multiple-choice questions in 45 minutes and contributes 30% of the Extended result.

Preparation should include:

• broad syllabus retrieval
• rapid equation and unit recognition
• diagram and graph interpretation
• elimination of distractors
• checking sign, scale and order of magnitude
• explaining why each wrong option is wrong after marking

Use short mixed sets first, then complete timed components. A correct answer obtained by guessing should still be reviewed.

Step 6: Prepare Paper 4 deliberately

Paper 4 contributes 50% of the Extended result and combines calculations, explanations, data, diagrams and practical knowledge.

For calculations:

1. identify the required quantity
2. write the equation
3. convert units
4. rearrange before substituting
5. show working
6. include the unit
7. check physical plausibility

For explanations, write linked cause-and-effect statements. Each sentence should add a distinct marking point rather than repeat the same idea in different words.

Example for gas pressure at constant volume:

Heating increases average particle kinetic energy. The particles move faster and collide with the walls more frequently and with a greater change of momentum. The force on the walls increases, so the force per unit area and pressure increase.

The exact number of points should match the marks available.

Step 7: Prepare Paper 5 or Paper 6 as a separate skill set

The practical component contributes 20%.

Paper 5 candidates

Practise:

• real apparatus setup
• instrument reading
• taking repeat measurements
• recording tables during the experiment
• plotting graphs and calculating gradients
• evaluating the method actually used
• safe and efficient working

Paper 6 candidates

Practise:

• reading scales and apparatus diagrams
• identifying independent, dependent and control variables
• completing tables with appropriate precision
• plotting best-fit lines or curves
• calculating gradients
• identifying limitations
• proposing specific improvements
• planning an investigation

Do not rely on generic answers such as “be more careful” or “repeat it.” State what is changed, which problem it addresses and why the evidence improves.

Use the Practical Skills Academy alongside the component-specific guide.

Step 8: Use full papers at the right time

A useful paper cycle is:

1. sit the correct component under the correct time
2. mark it using the official mark scheme
3. record the raw mark and section marks
4. classify every lost mark
5. select the highest-impact repairs
6. complete targeted practice
7. retry the skill without notes
8. sit another component and compare error patterns

Do not rush through many papers while the same mistakes remain uncorrected. Equally, do not stay on notes after the student needs mixed and timed application.

How should historical grade thresholds be used?

Use the official threshold table for the exact series and entry option. Paper variants and Paper 5 or Paper 6 combinations matter.

Historical thresholds can help answer:

• Is performance stable across several series?
• Is there a working margin above recent thresholds?
• Which component contributes the greatest avoidable loss?

They cannot guarantee the next threshold or final grade. The grade-boundaries guide explains the weighting and option process.

A weekly Extended revision structure

The amount of time should depend on evidence, but a balanced structure includes:

Some students need more sessions and others fewer. The important feature is the complete learning-correction-retry cycle.

How can progress be measured?

Track:

• number of red syllabus outcomes
• marks lost to units
• marks lost to algebra
• marks lost to incomplete explanation
• practical and graph marks
• unanswered questions
• timing overrun
• repeated errors after correction
• performance across several paper series

An isolated high percentage is weaker evidence than stable improvement with fewer recurring errors.

What should happen after a poor mock?

Do not immediately add random resources or more hours.

1. Confirm that the paper matched the current route and syllabus.
2. Separate untaught content from forgotten content.
3. Identify the three topics responsible for the largest share of lost marks.
4. Identify the largest repeated transferable skill error.
5. Repair those areas using targeted questions.
6. Retest them in a different paper.
7. Review whether the study method changed the error pattern.

The Year 11 revision plan gives 12-week, eight-week and four-week frameworks without promising a grade outcome.

The final two weeks

Use the final two weeks to stabilise rather than reinvent the system.

• retrieve equations, units and definitions regularly
• complete timed components selectively
• review recurring error categories
• practise graph and practical routines
• confirm component codes, timetable and permitted equipment
• correct recent errors without beginning large unrelated resources
• maintain sleep and recovery between examinations

Do not stop all content work on an arbitrary date if a required outcome is still missing. Prioritise essential gaps and realistic correction.

Can tutoring help?

Tutoring can shorten the diagnosis and feedback cycle when the tutor uses marked evidence.

A useful lesson should identify whether the current obstacle is:

• syllabus knowledge
• a misconception
• equation selection
• algebra or units
• written explanation
• practical reasoning
• timing

The student should then practise and reproduce the method independently. A tutor should not guarantee A*, a fixed improvement timeline or a particular threshold.

Final A* checklist

• Extended entry and practical component confirmed
• Current syllabus audited outcome by outcome
• Current equation and unit requirements secure
• Original topical practice completed for weak areas
• Paper 2 timing and distractor analysis practised
• Paper 4 calculations and explanations practised
• Paper 5 or Paper 6 skills practised separately
• Lost marks classified and repaired
• Corrected skills retested after a delay
• Performance stable across several complete papers
• Historical thresholds used only as context

An A* plan is not a fixed paper count or motivational slogan. It is a controlled system for finding lost marks, correcting their causes and demonstrating that the improvement holds under examination conditions.
