Online GCSE Chemistry tutors, matched to your child

GCSE Chemistry rewards using knowledge, not just recalling it. In England, Ofqual’s rules for GCSE Chemistry give knowledge and understanding a 40% weighting; the rest of the marks go to applying that knowledge and analysing information. Across all the marks, at least 20% must reward mathematical skills. Students must balance equations, carry out calculations, interpret practical data, and explain the behaviour of atoms and molecules at the same time. So knowing the content is not enough on its own, and a child who finds the maths hard can feel overwhelmed.

Foundation or Higher tier

In England, GCSE Chemistry is set at two tiers, and a student sits all their papers at one of them. Foundation tier leads to grades 1 to 5 and Higher tier to grades 4 to 9. Ofqual’s rules allow a grade 3 for a Higher student who narrowly misses grade 4, but one who falls well short is left unclassified, so the choice matters for a child near that line. The tier also changes what is examined. At AQA, for example, mole calculations, predicting how an equilibrium responds to a change in conditions and condensation polymers are Higher tier only, though students at both tiers study equilibrium and organic chemistry. Sessions can cover either tier, including the Higher-only content for a child on the borderline.

GCSE Chemistry or Combined Science

GCSE Chemistry on its own covers more than the chemistry in Combined Science. At AQA, most of the content is shared with Combined Science: Trilogy, and the extra is marked “chemistry only”. Of AQA’s eight required practicals, six are shared with Combined Science and two belong to GCSE Chemistry alone. A tutor can work on the chemistry in either course. If your child is taking Combined Science, say so on the form.

Where students typically fall behind

Two areas reach into much of the course: quantitative chemistry (moles, concentration, yield and atom economy calculations) and required practicals. AQA treats quantitative chemistry, with atomic structure and bonding, as groundwork for much of what follows: students are examined on it directly in Paper 1 and expected to apply it in Paper 2. For Higher tier students, that includes the mole. It is genuinely abstract, because it asks them to think about quantities of particles at a scale they cannot observe. OCR’s specification says the most common problem with these calculations is a weak grasp of ratios, and that most learners think a mole and a mass are the same thing.

Students may remember doing the required practicals in class but not remember why: what the method was designed to control, what the results actually showed, and how errors might have crept in. The written exams draw on them: at AQA, those questions count for at least 15% of the marks, and many test how well students apply what they know to practical situations, often in unfamiliar contexts.

What a GCSE Chemistry tutor typically covers

A good starting point is your child’s recent test results, which show the topics and question types costing marks. Typical focus areas include:

• Atomic structure and bonding: the difference between ionic, covalent and metallic bonding, and how structure explains properties such as melting point and conductivity.
• Equations: writing formulae and balanced equations for the reactions across the course, with ionic equations at Higher tier.
• Quantitative chemistry: relative atomic mass and concentration calculations, which sessions can work through step by step, as methods rather than formulae to memorise.
• Chemical changes: reactivity series, electrolysis (including half-equation writing at Higher), and the chemistry of acids and bases.
• Rates and equilibrium: interpreting rate graphs, understanding catalysts, and (for Higher) Le Chatelier’s principle and how to predict the effect of changing conditions.
• Organic chemistry: the alkane series, cracking and alkenes.
• Required practicals: working through each one.
• Exam wording: precise scientific language, practised on past papers. AQA’s examiners found imprecise language caused problems for many students on the June 2025 Higher tier Paper 1, such as writing “amount” instead of volume or mass.

The Higher tier notes in this list follow AQA’s specification; WJEC’s specification for Wales selects its own Higher-only content, so the split can differ by board. If one of these is the sticking point, say so in the details step of the form, with the tier (Foundation or Higher) if you know it.

The maths within chemistry

AQA’s specification lists the maths skills its GCSE Chemistry exams require. As well as mole calculations at Higher tier, students need to be comfortable rearranging formulae, working with standard form for very large and very small numbers, calculating percentages, and interpreting graphs. In England, none of it goes beyond GCSE Maths at the same tier. A tutor can look for gaps in mathematical technique and work on them alongside the chemistry content.

How exam boards differ

AQA and Edexcel are the most common boards in England, according to Ofqual’s market report. The required practical lists differ between boards, and so does the order of topics in the two papers.

AQA’s Paper 1 covers atomic structure, bonding, quantitative chemistry, chemical changes and energy changes, and its Paper 2 the rest, from rates of reaction to using resources.

In Wales, where WJEC is the largest awarding body, its GCSE Chemistry is graded A* to G, with A* to D at Higher tier and C to G at Foundation. Our Wales page covers the Welsh system more widely.

Put the board and specification on the form: they travel with your enquiry. If your child sits CCEA’s GCSE Chemistry in Northern Ireland, or a different qualification such as an International GCSE, say so there too. If you don’t know the board, the school will, and the tutor can work it out too, as our homepage says.

When should GCSE Chemistry tuition start?

At AQA, Edexcel and OCR, every GCSE Chemistry paper is sat in one exam season at the end of the course, in May and June. At WJEC, where the course is unitised and allows for staged assessment, the school may enter your child for a unit in an earlier summer. So there is no deadline for starting, only the time left before the written papers and, in Wales, before WJEC’s Unit 3, which falls in the first half of the spring term. An earlier start leaves room to secure the groundwork topics that later ones build on. A later start can focus on revision and on the question types costing the most marks.

Enquiring commits you to nothing. The first chat is free, and nothing starts until you say so.

How matching works

We read every enquiry ourselves and send it to one tutoring partner from our vetted network. You get two emails from us: a receipt, then one naming the partner. The partner’s team then gets in touch by WhatsApp, text or email to suggest tutors. Tutoring is one-to-one, typically over a video call with a shared whiteboard, anywhere in the UK. As our homepage sets out, lessons usually land at £25 to £35 an hour, and experienced teachers and examiners can reach £50. There are no placement fees, lessons are pay-as-you-go, and there is no obligation if it is not the right fit.
