Rapid recall · International AS Level

International AS Level Chemistry React15

First-year International AS recall decks for Cambridge and Edexcel International. The step up from iGCSE is mostly a step up in precision, and these are written to that standard.

Written for Cambridge (CIE) and Edexcel International.

Why it matters

Why this matters at International AS

  • International AS definitions are marked strictly - first ionisation energy, mean bond enthalpy, dynamic equilibrium. Nearly right earns nothing.
  • The volume of content arrives faster than at iGCSE, so gaps compound quietly unless something surfaces them each week.
  • Everything here is assumed knowledge in the second year. Time spent making AS content automatic is not revision, it is groundwork.

Topic decks

The International AS Level course, deck by deck

One deck per topic area, so you can work on the thing you are actually stuck on rather than shuffling the whole specification together. This is the shape of the International AS Level course and what each deck has to cover.

Decks are being written and uploaded now. Search the catalogue to see exactly what has landed so far.

  • Atomic structure

    Mass spectrometry, ionisation energies, electron configuration, orbitals

  • Amount of substance

    The mole, ideal gas equation, empirical formulae, titration calculations

  • Bonding

    Electronegativity, shapes of molecules, intermolecular forces, bond polarity

  • Energetics

    Enthalpy changes, calorimetry, Hess's law, mean bond enthalpies

  • Kinetics

    Collision theory, Maxwell-Boltzmann distributions, catalysts

  • Equilibria

    Dynamic equilibrium, Le Chatelier, Kc and its manipulation

  • Redox

    Oxidation states, half-equations, balancing redox reactions

  • Periodicity & Groups 2 and 7

    Trends across Period 3, alkaline earth metals, the halogens

  • Introductory organic

    Nomenclature, isomerism, alkanes, halogenoalkanes, alkenes, alcohols

  • Organic analysis

    Infrared spectroscopy, mass spectra, identifying functional groups

A routine that works at International AS Level

Run the International AS deck for the topic you are currently taught, plus one older deck chosen at random. The second one is what stops first-term content quietly disappearing across Cambridge and Edexcel International papers.
