How the course begins

  • Can write balanced equations and complete standard mole calculations
  • Can explain bonding, electrolysis, energy and rate observations
  • Has identified the Core or Extended paper route
  • Can commit to practical-data and timed-section work between lessons

Expected change

  • Use periodic patterns and structure–property relationships to explain inorganic chemistry.
  • Compare metal reactivity, extraction, corrosion and material choices using chemical and environmental evidence.
  • Trace organic families, reactions and polymers through clear formulae and reaction conditions.
  • Select and justify separation, identification and qualitative-analysis methods.
  • Plan fair investigations and produce reliable tables, graphs, conclusions and evaluations.
  • Integrate the complete 0620 syllabus under Core or Extended examination conditions.
How the programme adapts

Identify. Understand. Apply. Track.

Each cycle uses new evidence to decide what the student should work on next.

  1. Identify

    Find the immediate gap or recurring error.

    Example in this programmeCan write balanced equations and complete standard mole calculations

  2. Understand

    Build the chemical explanation behind the topic.

    Example in this programmeChoosing evidence for an unknown substance

  3. Apply

    Use the understanding in IB-style work.

    Example in this programmeUse periodic patterns and structure–property relationships to explain inorganic chemistry.

  4. Track

    Record progress and define the next priority.

    Example in this programmeSubmitted work is normally returned within three working days.
TEACHING EXAMPLE

Choosing evidence for an unknown substance

Incomplete response
The sample might contain chloride because a white solid formed.

Developed response
State the reagent and conditions, record the observation precisely, use the correct ionic change and distinguish the result from tests that could produce a similar precipitate.

Reasoning chain: method → controlled observation → chemical inference → limitation

  5. Week 5 — Industrial chemistry and resource use
  6. Week 6 — Organic formulae, fuels and homologous series
  7. Week 7 — Alkanes, alkenes and their reactions
  8. Week 8 — Alcohols, carboxylic acids and esters
  9. Week 9 — Polymers and macromolecules
  10. Week 10 — Separation methods and analytical reasoning
  11. Week 11 — Planning investigations, processing data and evaluating measurement quality
  12. Week 12 — Full Core or Extended exam practice and an individual review plan

Practice, feedback and parent visibility

Submitted work is normally returned within three working days. Feedback marks the point at which the reasoning broke down and turns recurring errors into later practice.

The student receives

  • Focused assignments between live lessons
  • Human feedback linked to the first broken reasoning step
  • A clear next practice priority in the learning space

A parent can see

  • Attendance and completion patterns
  • Recurring error areas and current priorities
  • A concise progress summary at agreed checkpoints

Workload and attendance

Allow about 3–4 hours each week for retrieval, practical-paper work, timed sections and corrections.

Cadence and lesson times are arranged individually, with review points used to adapt the pathway from evidence of progress.

Questions about this programme

Does Chemistry II finish the 0620 syllabus?

Together with Chemistry I, it covers the complete 2026–2028 content map plus practical and examination skills. The student's school remains authoritative for entry route and supervised practical requirements.

How is Core different from Extended in lessons?

Shared concepts are taught together. Supplement content, required depth and the correct paper combination are labelled explicitly, so students do not practise the wrong route.
