How the course begins

  • Has completed Cambridge 9701 topics 1–22 or equivalent AS teaching
  • Can solve multi-step mole and equilibrium problems
  • Can use AS organic mechanisms and interpret core spectra
  • Is sitting in 2027; 2028 candidates require a separate 2028–2030 syllabus review

Expected change

  • Apply lattice enthalpy, entropy, Gibbs energy and electrochemical models to unfamiliar systems.
  • Analyse advanced equilibrium and kinetic data with justified mathematical and chemical reasoning.
  • Explain transition-element chemistry through electronic structure, ligand exchange, redox and catalysis.
  • Construct advanced organic mechanisms and efficient multi-step synthetic routes.
  • Interpret combined analytical evidence to identify structure and assess purity.
  • Plan, analyse and evaluate Paper 5 investigations while communicating Paper 4 answers precisely.
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 programmeHas completed Cambridge 9701 topics 1–22 or equivalent AS teaching

  2. Understand

    Build the chemical explanation behind the topic.

    Example in this programmeUsing kinetics to constrain a mechanism

  3. Apply

    Use the understanding in IB-style work.

    Example in this programmeApply lattice enthalpy, entropy, Gibbs energy and electrochemical models to unfamiliar systems.

  4. Track

    Record progress and define the next priority.

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

Using kinetics to constrain a mechanism

Incomplete response
The mechanism looks plausible because the steps add to the equation.

Developed response
Derive the experimental rate law, identify which species must affect the rate-determining sequence, then reject any proposed mechanism whose elementary-step prediction conflicts with the evidence.

Reasoning chain: data → rate law → mechanistic constraint → defensible conclusion

  6. Week 6 — Advanced Group 2 and transition-element chemistry
  7. Week 7 — Arenes, phenols, acyl compounds and advanced carbonyl chemistry
  8. Week 8 — Amines, amino acids, proteins, polymers, stereochemistry and synthesis
  9. Week 9 — Multi-step organic synthesis strategy
  10. Week 10 — Combined spectroscopy and structure determination
  11. Week 11 — Integrated Paper 4 problems and targeted correction
  12. Week 12 — Paper 5 planning, data treatment, uncertainty and evaluation

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

A typical personalised plan allows about 4–5 hours each week for Paper 4 problems, synthesis, Paper 5 planning and correction; live lesson cadence is agreed individually.

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

Questions about this programme

Which syllabus version does A Level Chemistry II use?

The pathway shown is mapped to Cambridge 9701 for 2025–2027 examinations. Candidates sitting in 2028 receive an individual review against the 2028–2030 syllabus before their plan is confirmed.

How is Paper 5 prepared without replacing laboratory work?

Students practise planning, variables, data treatment, uncertainty and evaluation. The course does not replace supervised practical experience or the student's school and examination-centre requirements.
