As always, to fully resolve the quantitative problems you will need to know your Topic 1 and 11A.

  • 2 - all of atomic structure, e.g.,
    • notations $\ce{^M_ZX^{y+}_{n}}$
    • mass spectra & calc
    • isotopes / radio-isotopes
    • hydrogen spectra / energy level diagram
    • electron configuration
  • 3 - all of periodicity, e.g.,
    • terminologies
    • trends in physical properties (incl explanations)
      • ionization energy
      • electron affinity
      • electronegativity
      • atomic radii
      • ionic radii
    • chemical reactivities
    • 13.
  • 4 - Struture & Bonding
    • Identifying kinds of bonding
    • Properties of different bonding/structure
      • excl. properties from IMF
    • Lewis structures (incl. exceptions)
    • Shapes of molecules (2, 3, 4-domains only)
  • 5 - Energetics
    • enthalpy (diagram, def, endo/exo, eqn)
    • heat changes calc
    • experimental determination (combustion only; reaction in solution)
  • 10 - Organic Chem
    • Identifying functional groups by their Molecule Class names.

The trial exam uses a complete set of IB papers I (60 min) and II (2 h 15 min) from 2018. Please refrain from these in your practices.

Grade calculations

Term grades calculations are tabulated as follows:

Test Quizzes Labs
Term 1 80% 20% -
Term 2 60% 20% 20%
Term 3 80% 20% -

Composed grades are formed from term grades and exams:

Term 1 Term 2 Y1 exam Term 3 Trials IA
Year 1 20% 60% 20% - - -
PG (Nov) 15% 25% 30% 30% - -
PG (Nov)* 0% 30% 30% 40% - -
Term 4 - - - - 80% 20%

Predicted grades admit the following exceptions:

  1. language / background disadvantage. Students who had significant language/academic background deficiency will have their Term 1 grade omitted.[1]
  2. IA. IAs that are likely to be significantly better / worse than current performance gets a modifier. This is usually < Âą5%.

Once a term I email each of you a graph with all assessments plotted as a time-series. This is to help you help me make sure my numbers are legit, and for you to get a sense of your progression.

Grade boundaries

Our internal grade boundaries are based on the IB chemistry grade boundaries. The distribution is as follows:

% Grade
80+ 7
70-79 6
60-69 5
49-59 4
35-48 3
19-34 2

  1. Subjective things are me In practice I just calculate both variants for each student, and take the better one. Too-clever kids believe they can game the system and waltz throughout Term 1. ↩ī¸Ž
