How A-Level Physics Is Assessed

1. Written Examinations

The majority of the assessment comes from written exams. These typically include:

• Multiple-choice questions
• Structured short-answer questions
• Extended response/problem-solving questions

Exams assess understanding across all core topics, from fundamental principles to applied physics.

2. Practical Assessment

Students must complete a series of required practicals and write lab reports. These assess:

• Experimental design
• Equipment use and data accuracy
• Analysis and interpretation of results

Although practicals are not usually graded separately, they are essential for developing skills and may be indirectly assessed through exam questions.
