Chemistry

Quick Summary

Concepts & calculations – About 60% understanding concepts, 40% maths/calculations

Essential for Medicine – Usually required for medicine, dentistry, veterinary science, and pharmacy

What's it actually like?

IN A NUTSHELL

A-Level Chemistry combines written exams with practical work. You'll study organic chemistry (carbon compounds), inorganic chemistry (elements and their reactions), and physical chemistry (the theories behind why reactions happen).

You'll complete required practicals throughout the course, which are assessed through questions in your written exams. There's no separate practical grade, but you need to demonstrate practical competence to pass.

Expect lots of equations, mechanisms, calculations, and understanding chemical principles. It's about 60% understanding concepts and 40% applying calculations and learning reactions.

Chemistry sits between physics (very mathematical) and biology (more content-heavy), so it suits people who want a bit of both.

Student Studying

Maths matters more than you think: While not as mathematical as Physics, Chemistry includes significant calculations. A-Level Maths isn't required (though it helps), but you need to be comfortable with algebra, rearranging equations, and working with very large and very small numbers. Many students take Maths alongside Chemistry.

About the course

Is this for you?

  • Atoms, bonding, and calculations

    A-Level Chemistry starts with the basics of how substances are built and how they react. You'll study atomic structure, the periodic table, bonding, and how to calculate amounts of substances using moles and equations.


    Physical chemistry

    You'll move on to energy changes, rates of reaction, equilibrium, and electrochemistry. These topics focus on understanding how and why reactions happen, and how fast they occur.


    Organic chemistry

    A large part of the course is organic chemistry. You'll learn about different types of carbon-based molecules, how to name them, how they react, and how to work out reaction pathways and mechanisms.


    Inorganic chemistry

    You'll study elements and compounds, with a focus on transition metals and their properties.


    Practical work

    Throughout the course you'll carry out experiments and analyse results. Assessment is mainly through exams.

  • Chemistry is a good choice if you:


    • Enjoy seeing patterns in how substances react and transform

    • Like having a mix of learning content and problem-solving

    • Comfortable with maths (not as much as Physics, but it's still important)

    • Don't mind memorising significant amounts of information

    • Enjoy practical work and lab experiments

    • Can visualise molecules and structures in 3D


  • Analytical thinking - Learn to predict reactions, explain observations, and work out what's happening at a molecular level.

    Practical lab skills - Become proficient at techniques like titrations, distillation, chromatography, and preparing organic compounds.

    Mathematical applications - Calculations involving moles, concentrations, equilibria, and rates of reaction strengthen your numeracy.

    Problem-solving - Working out reaction mechanisms and solving equilibrium problems requires logical, step-by-step thinking.

    Pattern recognition - Chemistry is full of trends and patterns. You'll learn to spot them and use them to predict new scenarios.

    Attention to detail - Small differences in structure or conditions can completely change chemical behaviour.

  • There's a LOT to learn. Chemistry is content-heavy. You need to know reactions, mechanisms, functional groups, trends, and theories. It rewards consistent revision throughout the course.


    Organic chemistry is a different beast. Some people love drawing mechanisms and working out synthesis routes. Others find it abstract and confusing. It's a major part of the course, so you need to be ready for it.


    Practicals require precision. You need good hand-eye coordination and patience. Some experiments require extremely careful technique to get valid results.


    The GCSE jump is significant. A-Level Chemistry goes much deeper. If you found GCSE Chemistry challenging, think carefully. You'll typically need at least a grade 6, ideally 7+.

  • Biology + Chemistry + Maths = Classic for medicine and life sciences

    Chemistry + Physics + Maths = For chemistry, chemical engineering, or natural sciences

    Biology + Chemistry + Psychology = For biomedical sciences

  • Chemistry rewards consistent revision and active learning. Here's how to succeed:


    Make flashcards early – Start making flashcards for reactions, functional groups, and definitions from day one. Review them regularly – little and often beats cramming.


    Draw mechanisms repeatedly – For organic chemistry, practice drawing mechanisms over and over until they're automatic. Understanding the electron movement is key.


    Link topics together – Chemistry topics connect – organic, inorganic, and physical chemistry overlap. Look for links between different areas to deepen understanding.


    Engage with practicals – Don't just go through the motions in practicals. Understand why you're doing each step and what the results tell you. This understanding pays off in exams.

  • Chemistry graduates can go onto to work in:


    • Pharmaceuticals

    • Healthcare

    • Chemical industry

    • Environmental science

    • Forensics

    • Teaching

    • Research

    • Materials science

    • Food science

    The analytical skills also translate to business, finance, and law.

  • Chemistry A-Level is essential for degrees in:


    • Chemistry 

    • Medicine, Dentistry, Veterinary Science

    • Pharmacy and Pharmacology


    It is also strongly recommended for degrees in:


    • Chemical Engineering

    • Forensic Science

    • Biochemistry

    • Environmental Science

    • Some Biology degrees


    Top tip: For Medicine and related degrees, you'll usually need Chemistry plus Biology. Many Chemistry degrees also prefer or require Maths.

  • Ask yourself:


    • Did I enjoy GCSE Chemistry and find it manageable (grade 6+)?

    • Am I comfortable with both learning content and doing calculations?

    • Do I find the idea of practical lab work appealing?

    • Am I willing to learn and memorise significant amounts of information?

    • Do I want to keep medicine, dentistry, or science degrees as options?

    • Can I handle maths at a decent level (even if not taking A-Level Maths)?

    If you're answering yes to most of these, Chemistry could be a great fit.

Gateway to healthcare: Chemistry is particularly important if you're considering any healthcare profession – it's usually required for medicine, dentistry, and pharmacy.
