    About AQA A-Level Physics

    AQA A-Level Physics (7408) is a linear two-year course designed to deepen your understanding of the physical world, from subatomic particles to cosmic scales. You will explore fundamental principles and their applications, developing a robust scientific methodology through theoretical study and hands-on practical work. The course builds on GCSE knowledge, encouraging you to question how and why things happen, and to appreciate the elegance of physical laws.

    The specification is structured into core topics that progressively link concepts, fostering synoptic understanding. In the first year, you cover measurements and their errors, particles and radiation, waves, mechanics and materials, and electricity. The second year extends into further mechanics and thermal physics, fields (gravitational, electric, magnetic), and nuclear physics, plus an optional module that allows you to specialise in an area like astrophysics or medical physics. Practical skills are integral, with 12 required practicals developing your lab competency.

    This course hones analytical thinking, problem-solving, and mathematical skills—approximately 40% of marks require maths. It prepares you for higher education in physics, engineering, or related sciences, and nurtures a lifelong appreciation for the role of physics in technology and society. The linear assessment means exams at the end of Year 13 test your cumulative knowledge, encouraging deep, sustained learning.

    Assessment Structure

    AQA A-Level Physics is assessed via three written examinations at the end of the two-year course. Paper 1 (2 hours, 85 marks, 34%) covers core content from the first year plus periodic motion; Paper 2 (2 hours, 85 marks, 34%) covers the second year core topics of thermal physics, fields, and nuclear physics, along with assumed knowledge; Paper 3 (2 hours, 80 marks, 32%) includes Section A on practical skills and data analysis (45 marks) and Section B on the chosen optional topic (35 marks). All papers feature a mix of long and short answer questions, with multiple-choice questions only in Paper 3 Section A. Additionally, students must complete a practical endorsement, which is assessed by teachers through 12 required practicals and reported separately as a Pass or Fail.

    Why Choose AQA?

    • AQA's specification is widely used and well-supported, with a wealth of high-quality textbooks, online resources, and past papers. The clear layout and familiar question style help students transition confidently from GCSE, especially if they have previously studied AQA Science.
    • The choice of optional topics (such as Astrophysics, Medical Physics, Engineering Physics, Turning Points in Physics, and Electronics) allows students to tailor their learning to their interests and future career aspirations, providing motivation and depth.
    • AQA places a strong emphasis on practical skills, with a dedicated practical endorsement that develops lab competence and scientific thinking, valued by universities and employers. The specification also requires robust mathematical skills, preparing students well for further study in physical sciences and engineering.

    Common Exam Mistakes

    Pitfalls to avoid in your exams

    • •Confusing precision with accuracy
    • •Failing to convert units correctly before performing calculations
    • •Incorrectly combining uncertainties (e.g., adding percentage uncertainties when values are added)
    • •Ignoring the relationship between significant figures and uncertainty
    • •Misinterpreting error bars on graphs

    Top Examiner Tips

    Expert advice for exam success

    • •Always check that units are consistent before starting a calculation
    • •When calculating percentage uncertainty, ensure the number of significant figures in the final answer matches the precision of the data
    • •Remember that the gradient of a line of best fit is not the only way to analyze data; consider the worst-fit line to determine uncertainty in the gradient
