If you are taking Combined Science and thinking about A Level Chemistry, you are not alone. It is one of the most common questions parents and students ask. The answer depends on your grades, the school you choose and how you prepare. Here is what to check and what to do.
What sixth forms usually look for
Every school and college sets its own entry rules, so there is no single answer. Typical examples include a grade 6 or 7 in Chemistry, or a double grade such as 6-6 or 7-7 in Combined Science, and often a solid grade in Maths too. Some sixth forms accept Combined Science, some prefer Triple Science, and some ask for the separate Chemistry GCSE for A Level Chemistry. Always read the entry requirements on the website of each school or college you are considering, or ask the admissions team.
Why Maths matters
A Level Chemistry includes many calculations, from moles and concentrations to energy changes and rates. Students who are confident with algebra, fractions, standard form and rearranging equations usually find the course more manageable. If your Maths is weaker, work on it alongside Chemistry.
What Combined Science may not cover in depth
Combined Science covers Biology, Chemistry and Physics in one course, so it covers less Chemistry than the separate GCSE. Depending on your exam board, some topics may be covered lightly or not at all, and you may have had less practice with calculations and organic chemistry. This does not stop you from succeeding at A Level. It means you should find out what is missing and fill it.
How to prepare, step by step
- Check the entry requirements of the sixth forms you are considering, and ask whether Combined Science is accepted for A Level Chemistry.
- Look at the A Level syllabus. The first topics usually build on atomic structure, bonding, the mole and organic chemistry.
- Master the mole. Work through our mole and stoichiometry notes and practise until the calculations feel easy.
- Revise atomic structure and bonding. Our atomic structure notes are a good start.
- Learn the basics of organic chemistry, including the names of simple alkanes, alkenes and alcohols and their main reactions.
- Practise exam-style questions and keep a log of the mistakes you make, so you can fix them.
What if my school requires the separate Chemistry GCSE?
- Ask whether there is a bridging course or an entry test that lets you start A Level Chemistry anyway.
- Ask whether a strong Combined Science result with extra study would be considered.
- Look at other sixth forms or colleges nearby that accept Combined Science.
- Consider extra tuition to cover the missing content before the course starts.
Is Combined Science enough for a science career?
Many students go on to study sciences, medicine or engineering after a Combined Science GCSE. The most important qualifications for university are your A Levels or equivalent, together with the entry requirements of each course. If you are thinking about a specialist course, check its requirements early.
If you are still choosing between the two routes, read our guide to Combined Science and Triple Science.
Frequently asked questions
Can I take A Level Chemistry with only Combined Science?
Often yes, if you have strong grades and your sixth form accepts it. Requirements differ between schools, so check each one.
What grade do I need in Combined Science for A Level Chemistry?
It depends on the school. Many ask for around 6-6 or 7-7, but some ask for more. Look at the entry requirements on the school’s website.
Will I be behind students who took Triple Science?
You may be missing some content, but many students catch up with preparation and regular practice in the first term.
Is A Level Chemistry hard?
It is demanding, with more depth and more calculations than GCSE. Students who work steadily and practise problems regularly do well.
