Key Components of the OCR Physics A G484 June 2013
Markscheme
When reviewing the markscheme, it’s important to focus on several core areas that
frequently appear in the G484 exam.
1. Experimental Methodology and Design
Questions often ask students to describe or critique experimental setups. The
markscheme rewards clarity in explaining the steps for measurement, the controls in
place, and how variables are managed. For instance, students might be required to
explain how to measure a physical quantity accurately or how to minimize systematic
errors.
Tips for students:
Be precise when describing apparatus arrangement.
Mention how to ensure repeatability and reliability.
Highlight any safety considerations if relevant.
2. Data Analysis and Interpretation
A significant portion of marks comes from analyzing data tables, graphs, and calculations.
The markscheme shows that examiners look for correct use of formulas, accurate
substitution of values, and correct units. Furthermore, interpreting results — such as
explaining trends or anomalies — is crucial.
Tips for students:
Check units carefully throughout calculations.
Use significant figures appropriately.
Practice drawing and interpreting graphs, including best-fit lines and error bars.
3. Error Analysis and Uncertainty
Understanding uncertainties and errors is a vital part of practical physics. The OCR Physics
A G484 June 2013 markscheme includes marks for identifying sources of error, calculating
uncertainties, and suggesting improvements to reduce errors.
Tips for students:
Learn how to estimate random and systematic errors.

instruments or repeating measurements.
How to Use the OCR Physics A G484 June 2013 Markscheme
Effectively
Simply reading the markscheme is not enough; you need to actively engage with it to
boost your exam performance.
Analyze Your Practice Answers
After attempting past paper questions, compare your answers with the markscheme.
Identify where you lost marks and understand why. Was it due to missing key details,
incorrect calculations, or a lack of explanation? This analysis helps pinpoint weaknesses.
Focus on Command Words
The markscheme closely follows the command words in questions, such as “describe,”
“explain,” “calculate,” or “suggest.” Each command word demands a different depth of
response. For example, “describe” requires straightforward facts, whereas “explain” asks
for reasoning.
Practice Marking Peer Work
If possible, practice marking answers written by classmates or sample answers. Using the
markscheme to award marks helps internalize the marking criteria and sharpens your
ability to write answers that meet these standards.
