What Will Students Learn?

AS Level (Year 12) - Core Chemical Principles

Students establish a strong foundation: atomic structure, bonding theories, periodicity, states of matter, chemical energetics, reaction kinetics, chemical equilibria and basic redox processes. Core principles such as acid-base chemistry, moles and stoichiometry, gases, solutions and energy changes. Practical laboratory work reinforces understanding through experiments, quantitative measurement and data handling.

A-Level (Year 13) - Advanced Chemistry and Applied Concepts

Year 13 deepens into advanced inorganic, physical and organic chemistry - including reaction mechanisms, energetics, electrochemistry, thermodynamics, kinetics, organic synthesis, environmental chemistry and industrial chemical processes. Topics include equilibria in dynamic systems, chemical bonding in transition metals, spectroscopy, polymer chemistry, and analytical methods.

Skills & Understanding Developed

  • Quantitative reasoning and precise measurement
  • Critical evaluation of chemical data and logical problem-solving
  • Balancing theoretical knowledge with practical laboratory skills
  • Interpreting experimental results and understanding error margins
  • Communicating findings in clear scientific writing
  • Analytical thinking, attention to detail, and mathematical competence
  • Experimental planning - essential for advanced study in chemistry, engineering or applied sciences
