A-Level Chemistry,
mechanism by mechanism.
Cambridge 9701 and Edexcel International A-Level Chemistry. From bonding and equilibria in AS to organic mechanisms and transition metals in A2 — coached by examiner-trained specialists with full Paper 5 practical technique.
The central science. Physical, inorganic and organic coverage across five papers — essential for medicine, natural sciences and chemical engineering.
Chemistry is won on organic mechanisms and calculations.
A-Level Chemistry is the single most common cause of dropped grades in Vietnamese international school cohorts. Students arrive from IGCSE confident — and are quickly overwhelmed by the sheer content volume of equilibria, kinetics, electrochemistry, transition metals and multi-step organic mechanisms. Most plateau at grade C.
Where the difficulty actually lives
It is not the memorisation. It is the calculations (Ka, Kb, Kc, pH, buffer systems, Born-Haber cycles) and the organic reaction maps (8+ functional groups interconverting across 20+ named reactions). Students who do not systematise these two areas in AS never catch up in A2.
How we teach it
Every Times Edu Chemistry student works from a single mechanism map that sits in front of them for every lesson. By week 6 they can draw any organic transformation on the syllabus from memory. By week 10 they can tackle any 6-mark Paper 4 structured question with confidence.
The full content we cover in 1:1 lessons.
Every Times Edu Chemistry mentor maps lessons directly to the official syllabus objectives — nothing on the real paper is a surprise.
Atomic Structure & Bonding
Electron configuration, ionic, covalent and metallic bonding.
Equilibria & Kinetics
Kc, Kp, Le Chatelier, rate equations, Arrhenius.
Acids, Bases & Buffers
pH calculations, Ka, Kw, buffer systems, titration curves.
Thermodynamics
Enthalpy, entropy, Gibbs free energy, Born-Haber cycles.
Periodicity
Group 2, Group 17, Period 3 trends.
Transition Metals
d-orbital splitting, complex ions, redox titrations.
Reaction Mechanisms
Nucleophilic substitution, elimination, addition, condensation.
Synthesis & Spectra
Multi-step synthesis, IR, mass spec, NMR interpretation.
The papers your child will actually sit.
Knowing what each paper tests — and how it is marked — is half the battle. Here is the full breakdown.
Multiple Choice AS
Forty multiple-choice questions covering AS content.
AS Structured
Short-answer AS questions with some calculation.
A2 Structured
Long-answer A2 questions including synthesis and mechanisms.
Planning, Analysis & Evaluation
Experimental design, data handling and uncertainty analysis.
Why even strong students lose grades here.
These are the three traps we see most often in diagnostic sessions with new A-Level Chemistry students — and every one of them is fixable.
Mole calculation errors
Multi-step mole calculations appear on every A2 paper and are where strong students lose 8–12 marks per exam. We drill them weekly from week 1.
Incomplete mechanisms
The mark scheme awards curly arrows for the bond breaking, bond forming and the attacking nucleophile. Students who draw just the starting and ending states lose most of the marks.
Equilibrium sign errors
Le Chatelier questions trip up almost every student on first exposure. We build the intuition before drilling the mark-scheme language.
From AS to final A2.
I was a D at Chemistry mocks in December. Eight months with Times Edu and I walked out of A2 with an A*. They rebuilt the entire subject from AS foundations up.
What families always ask about Chemistry.
Have a specific question about your child's situation? Book a free 60-minute diagnostic and our specialist will answer every one.
Is A-Level Chemistry harder than Physics or Biology?
For most students, yes — the content load is enormous and the calculations are unforgiving. Students who are strong at maths find Chemistry more manageable; students who are stronger at memorisation often prefer Biology.
Can you help if my child is stuck on organic mechanisms?
This is one of the most common starting scenarios. Organic chemistry is a pattern-recognition subject, not a memorisation subject. We teach the patterns first, drill them to automaticity, and then the "memorisation" becomes self-generating.
How does Cambridge 9701 differ from Edexcel IAL WCH?
Content overlap is about 90%. Edexcel splits content into 6 modular units (U1–U6); Cambridge uses 5 papers. Marking conventions differ slightly. Your mentor will be matched to your child's board.
Is Chemistry essential for medicine?
Yes — almost universally required by medicine programmes at UK, Australian, Canadian and Singapore universities. A* or A is typically the minimum. Plan for this from the start of AS.
