A-Level Chemistry can feel like a big step up. We match your child with a one-to-one tutor who understands their exam board, explains difficult ideas clearly and helps them approach calculations, mechanisms and exam questions with more confidence.
Course-specific support
The jump from GCSE can feel sudden. Ideas become more abstract, calculations become longer and exam questions expect greater precision. We focus lesson time on the parts your child actually needs help with.
Need help across several subjects? Explore our broader A-Level tutoring service.
Exact specification first
Two students can study the same Chemistry topic but sit very different papers. We confirm the exact course first, so the tutor, questions and revision plan all stay relevant.

Focused support for physical, inorganic and organic Chemistry, mathematical skills, required practical knowledge, synoptic questions and preparation for Papers 1, 2 and 3.
A-Level Chemistry
Lessons follow the student's specification and can target current units, multi-step calculations, organic pathways, practical understanding, data interpretation and structured exam responses.
International students: we also cover Pearson Edexcel International A Level (IAL) Chemistry, unit by unit, including the practical-based written papers. Tell us your unit codes and we match the tutor and practice material to them.
OCR A / OCR B Salters
We confirm whether the student follows OCR A or OCR B Salters before recommending a tutor, so lessons and practice stay relevant to the right course.
9701
Full AS and A Level cover for Cambridge 9701, taught paper by paper.
AS students build the base properly. A2 students go straight at the hard topics: equilibria, electrochemistry, transition elements and the organic synthesis routes that decide top grades.
Exam technique
Knowing chemistry and scoring in chemistry are two different skills. Our tutors train both.
Past-paper questions grouped by topic, so a weak topic gets fixed before it costs marks in a full paper.
Every answer marked against the official mark scheme. Students learn the exact wording examiners pay for.
Real papers under real timing, with pacing feedback after each one.
Repeated errors tracked lesson by lesson, so the same lost mark does not happen twice.
Chemistry diagnosis
Sometimes the knowledge is there, but the marks still do not follow. The problem may be application, units, terminology, practical reasoning or timing. Finding that cause is the first step towards useful tuition.
Knows reactions but forgets mechanisms
Pattern understanding
Gets the method right but loses final calculation marks
Units, signs or multi-step working
Understands theory but struggles with unfamiliar questions
Application
Loses marks on practical questions
Method, data or evaluation
Organic Chemistry feels like memorisation
Weak reaction relationships
Paper 3 performance is weaker
Synoptic and practical application
Extended answers are vague
Chemical terminology and precision
Runs out of time
Exam planning and question prioritisation
Core Chemistry branches
The course feels more manageable when students can see how its main branches connect. Tutors explain the ideas clearly, then help students use them in calculations and exam questions.
Build a clearer understanding of atomic structure, bonding, energetics, kinetics, equilibria, acids and bases, thermodynamics, electrochemistry and rate equations.
See the connections between periodicity, group chemistry, transition metals, complex ions, redox chemistry, trends and reactions instead of memorising isolated facts.
Make sense of functional groups, isomerism, reaction pathways, mechanisms, aromatic chemistry, carbonyl chemistry, amines, polymers and synthesis.
Calculation confidence
A correct idea can still lose marks through one missed unit or an unclear step. A consistent method helps your child work more accurately and check whether an answer makes chemical sense.
Identify data → choose the relationship → substitute correctly → track units → calculate → check whether the answer is chemically reasonable
Mole calculations
Concentration and gases
Percentage yield and atom economy
Energetics
Equilibrium constants
Rate equations
pH and logarithms
Electrochemistry
Uncertainty and data interpretation
High-friction topics
Organic mechanisms
The tutor shows your child where electrons move, why bonds change and how reaction conditions shape the pathway. This gives unfamiliar mechanisms a pattern they can follow.
Practical skills
Lessons help students explain methods, interpret results and evaluate experiments with more precision. Required laboratory work still takes place through the student's school.
Spectroscopy and synthesis
Students learn how spectra, structures, reagents and conditions connect. Instead of guessing, they follow the evidence towards a supported conclusion.
Paper 3 and synoptic work
Where the student's board uses this structure, lessons practise unfamiliar data, practical reasoning, linked concepts and multi-step questions in a calm, structured way.
Year 12 (AS): atomic structure, bonding, energetics, kinetics, equilibria, intro organic.
Year 13 (A2): entropy and Gibbs free energy, electrode potentials, transition metals, aromatic chemistry, polymers, and multi-step synthesis. Students can join for one hard topic without restarting the whole course.
Hong Kong
Many of our A-Level chemistry students study in Hong Kong, mostly on Cambridge 9701 and Edexcel International A Level (IAL). Lessons are online and 1-to-1, scheduled in Hong Kong time (GMT+8), with evening and weekend slots around the school day.
Your child gets the same tutor every lesson, a plan built around their school tests and predicted grades, and past-paper practice matched to their exact board. Start with a free 30-minute trial lesson.
Families across the city can also meet our online tutors in Hong Kong, and younger students can start with our IGCSE chemistry tutors.
Existing tutor profiles
A good match is about more than qualifications. We consider the student's course, current difficulty, preferred teaching style and availability before recommending a tutor.

Tell us the year, exam board, current topics, recent results, main concerns and lesson times that work for your family.
We look for the right balance of Chemistry knowledge, A-Level experience, board familiarity, teaching style and availability.
Your child meets the recommended tutor, discusses current priorities and experiences the teaching style before you commit to regular lessons.
Lessons focus on the areas that matter now. If the match does not feel right, you can ask us to recommend another tutor.
Clear starting rate
The exact rate depends on the tutor and the support your child needs. We confirm it clearly before regular lessons begin, with no hidden fees.

Parents should not have to piece progress together from scattered messages. The Combo platform keeps sessions, resources, feedback and current priorities organised in one place.
Why Combo Tutors
Your child receives focused one-to-one teaching, while the Combo Tutors team helps manage the match, communication and support around every lesson.
We check the student's actual course before recommending a tutor or choosing practice material.
Lessons address what is causing lost marks instead of taking the student back through the whole syllabus.
The tutor can adapt every explanation, calculation and question to your child's needs.
Our team reviews the requirement and recommends a relevant tutor, so you do not have to compare hundreds of profiles.
If the first tutor is not right for your child, you can ask us for another recommendation.
The Combo Tutors team helps with scheduling, communication and tutor concerns throughout the relationship.
