Grab the combined PDF, or pull individual chapters below.
Print it, or load it on your iPad before lessons.
Use the lookup map before Paper 2 and Paper 3 practice.
It cuts through the tables, constants, and spectrum ranges quickly.
Lock in atomic structure, bonding, and the mole concept first.
Energetics, kinetics, and equilibria all assume the foundations.
Topic 11 is where most students lose marks under exam time.
Map every functional group conversion before attempting questions.
SEAB provides constants and Eᶿ values, but not the equations.
Memorise the formulae outside the booklet — examiners assume it.
Going deeper? Data Booklet guide · Formula Sheet guide · Organic reactions summary · Paper 2 structured strategy.
Paper weightings, marks, core topic map, and a revision plan based on the official SEAB syllabus PDF.
Key constants, tables, and reminders for the written papers (Papers 1-3).
Yes. These free H2 Chemistry notes follow the latest SEAB 9476 syllabus, and you can download the complete bundle PDF or each topic PDF chapter-by-chapter.
Yes - scroll to the topic list and use the “Download PDF” link for each chapter (Atomic Structure → Transition Elements), or use the full bundle PDF at the top.
Yes - the notes track the 2026–2027 SEAB H2 Chemistry (9476) structure across all 13 topics, plus exam-format guidance for Papers 1–4.
For 2026, SEAB publishes the H2 Chemistry syllabus PDF as 9476; 9729 appears on SEAB’s 2026 list as an outgoing syllabus. Use the 9476 syllabus + data booklet when revising.
What SEAB provides in the Data Booklet versus what you still need to memorise.
Paper 1 to 4 structure, weightings, and pacing tactics across MCQ, structured, free response, and practical.
Quantum numbers, electron configurations, ionisation energy trends, and PES evidence.
VSEPR shapes, bond polarity, intermolecular forces, and lattice energy trends.
Periodic trends, Period 3 patterns, and Group 2/17 reactivity storylines.
Mole calculations, limiting reagents, redox titrations, and analytical stoichiometry.
Ionic equilibria, solubility equilibria (Ksp), hydrolysis, complex ions, and QA.
Functional groups, mechanisms, synthesis planning, and spectroscopy interpretation.
Redox, electrochemical cells, standard potentials, Nernst, and electrolysis design.
Complex ions, colours, variable oxidation states, ligand chemistry, and catalysis.
SEAB provides a Chemistry data booklet (tables/constants), not a full formula sheet. Learn what’s provided vs what you still need to memorise using the formula-sheet guide linked on this page.
Use the Paper 1–4 format guides for pacing and mark breakdowns, then pair Paper 4 prep with the practicals hub so you rehearse planning, PDO, and ACE under time pressure.
The official SEAB Chemistry Data Booklet (covers 8873/9476/9813) is linked at the top of this page. It contains constants, standard electrode potentials, and thermodynamic data - but no formulae, so learn your equations separately.
The official SEAB H2 Chemistry (9476) syllabus PDF is available for free download from the SEAB A-Level syllabuses page. Our H2 Chemistry Syllabus 2026-27 guide links directly to the official PDF and covers paper format, topic list, specimen papers, and the companion data booklet.
The SEAB Chemistry Data Booklet (for 8873/9476/9813) includes the Periodic Table, selected physical constants, thermodynamic data, standard electrode potentials, bond energies, and ionisation energies. It does NOT contain formulae - you must memorise equations for rate laws, Hess's Law, Nernst equation, etc. Our Data Booklet guide explains every table and what you still need to learn by heart.
Yes - the Data Booklet includes a Periodic Table of Elements with atomic numbers and relative atomic masses. You do not need to memorise the table, but you must know trends (ionisation energy, electronegativity, atomic radius) and group-specific chemistry.
Yes - all our H2 Chemistry notes are free. Download the full bundle PDF or grab individual topic PDFs from the Topic Outline below. We cover all 13 H2 Chemistry topics (Atomic Structure through Transition Elements), aligned to SEAB 9476.
Most students find Organic Chemistry (Topic 11) the hardest because it demands memorising dozens of reaction mechanisms and reagent conditions. Chemical Equilibria (Topic 9) and Electrochemistry (Topic 12) also rank high because they combine conceptual reasoning with quantitative calculation - a skill gap that only closes with consistent practice on multi-step problems.
The SEAB 9476 syllabus has 13 core topics: (1) Atomic Structure, (2) Chemical Bonding, (3) The Gaseous State, (4) Theories of Acids and Bases, (5) The Periodic Table, (6) Mole Concept and Stoichiometry, (7) Chemical Energetics, (8) Reaction Kinetics, (9) Chemical Equilibria, (10) Chemistry of Aqueous Solutions, (11) Organic Chemistry, (12) Electrochemistry, and (13) Transition Elements.
The 9476 syllabus replaces the outgoing 9729. Key changes include a restructured practical component (Paper 4 now emphasises planning, data-handling, and evaluation over rote lab techniques), realigned topic numbering, an updated data booklet, and greater emphasis on green and sustainable chemistry within the organic topics.
Start by reading each topic summary to identify your weak areas. Then download the relevant chapter PDF and work through the embedded examples. Cross-reference each chapter with the Data Booklet guide to know which constants and tables are provided. Finish by doing timed practice with the Paper 1–4 format guides linked on this page.
Yes - H2 Chemistry covers all 13 SEAB topics in greater depth, includes Paper 3 (free response) and Paper 4 (practical), and requires more quantitative problem-solving. H1 Chemistry covers a smaller subset of topics and has no practical exam. If your university course requires Chemistry, check whether H1 or H2 is specified.
Most competitive courses (Medicine, Dentistry, Pharmacy at NUS/NTU) expect at least a B in H2 Chemistry. Engineering and science programmes typically require a C or better. Always check the specific faculty's admission criteria, as requirements vary across universities and change by intake year.
Build an organic synthesis flowchart linking functional groups to their interconversion reactions - our Organic Synthesis Flowchart guide (linked on this page) provides a ready-made map. Then drill mechanism writing daily: draw the curly arrows, label the nucleophile and electrophile, and state the conditions. Repetition with mechanism maps beats passive re-reading.
Start active recall and spaced practice from the beginning of JC1 - do not wait until JC2. By the end of JC1, you should have strong foundations in Topics 1–9. Use our JC1-to-JC2 Study Plan (linked on this page) to set monthly targets. Intensive timed-paper practice should begin at least 4–5 months before the A-Level exams.
