Question 1

How do I get full marks on a 6-mark question in Pearson Edexcel International GCSE Physics?

Accepted Answer

Extended open-response questions in Pearson Edexcel International GCSE Physics are marked using a levels-of-response approach, which means examiners reward the overall quality and coherence of your answer rather than simply counting individual bullet points. To reach the top level, your response needs to demonstrate solid physics knowledge (AO1), apply that knowledge to the specific context the question sets (AO2), and where relevant show you can analyse or evaluate evidence (AO3). We'd suggest planning briefly before you write, aiming to cover all aspects of the question using accurate scientific terminology and linking your ideas in a logical sequence. Our exam practice section includes extended open-response questions where you can work through this approach and check your answers against the mark scheme to identify any gaps in your reasoning.

Question 2

What do the levels in the Pearson Edexcel International GCSE Physics mark scheme mean?

Accepted Answer

Extended open-response questions in the Physics paper use a levels-of-response mark scheme, which means the examiner reads your whole answer and places it into a level based on the overall quality of your scientific reasoning, rather than simply ticking off individual points.

A lower-level response might identify some relevant physics but lacks clear links between ideas, whereas a higher-level response builds a coherent, well-structured explanation that uses accurate scientific language throughout. The spec confirms these extended open-response questions appear alongside multiple-choice, short-answer and calculation questions, so understanding how to approach each style is worthwhile. Our exam practice includes extended-response questions with model answers so you can see exactly what a top-level response looks like and use active recall to practise building that kind of answer yourself.

Question 3

What's the difference between Cognito's exam practice and past papers?

Accepted Answer

Past papers give you the full 2-hour, 110-mark Physics Paper 1 experience in one go, which is genuinely useful closer to exam day when you want to rehearse the whole paper from start to finish. Our exam practice is organised by topic, so you can target the exact areas of the 4SD0 Physics content where you need more work, rather than spending time on questions covering material you already understand well.

We'd suggest using our exam practice to build confidence topic by topic first, then turning to past papers once you feel ready to tackle the full paper. Using our by-topic view to spot gaps, then going back to our notes or flashcards to address them, is a great way to make each revision session count before you move on to full-paper practice.

Question 4

How long should I spend on each question in the exam?

Accepted Answer

The Physics Paper 1 runs for 2 hours (120 minutes) and carries 110 marks, which works out to roughly 1 minute per mark as a useful rule of thumb. Since the paper includes a mix of multiple-choice questions, short-answer questions, calculations and extended open-response questions, you won't spend the same amount of time on every question.

We'd suggest moving through shorter, lower-mark questions fairly quickly, saving more time for the extended open-response questions that carry more marks. Keeping an eye on the clock as you work through each section helps you stay on pace without lingering too long on any single question.

Our exam practice lets you work through questions by topic, which helps you build a sense of how much time and working each question type needs before your real exam.
