IB Diploma · Chemistry

IB Chemistry, on the syllabus your child is actually sitting.

Content-heavy and technically unforgiving. Most students who underperform know more chemistry than their grade suggests — they are losing marks on terminology, equation notation and answer structure. That is a faster problem to fix than the syllabus.

Both levels sit Paper 1 and Paper 2. Under the current syllabus, first assessed in 2025, there is no Paper 3 and there are no options. [TO CONFIRM — Glen] verify against the current IB Chemistry subject guide before launch.

Chemistry · Standard Level

SL — the full conceptual spine, at standard depth.

The current syllabus organises everything under Structure 1–3 and Reactivity 1–3. SL students meet every one of those themes; the difference at Higher Level is depth and extension, not a separate list of topics.

StructureModels of the particulate nature of matter, the periodic table and periodicity, chemical bonding and structure
ReactivityEnergetics and thermochemistry, kinetics, equilibrium, acids and bases, redox, organic foundations
PapersPaper 1 (multiple choice and data-based) and Paper 2 (extended response)
Internal AssessmentIndividual scientific investigation — 20% of the grade
Common failureKnowing the chemistry and writing it in language the rubric does not credit
We focus onChemical terminology, state symbols and equation notation, and answer structure the examiner can mark

Chemistry · Higher Level

HL — the extensions, and where most of the pain lives.

Everything in SL plus the Higher Level extensions, with substantially more quantitative work throughout. Organic chemistry and spectroscopy are reliably the two sections students arrive asking for help with.

Additional contentOrganic synthesis and reaction mechanisms, spectroscopic identification (NMR, mass spectrometry, IR), electrochemistry, entropy and spontaneity, advanced equilibrium and acid–base calculations
PapersPaper 1 and Paper 2, with HL-only content and greater quantitative demand
Internal AssessmentIndividual scientific investigation — 20% of the grade
Common failureOrganic mechanisms learned as a list to memorise rather than a system to reason through
We focus onMechanism types first, then reaction pathways, then spectroscopic identification — each practised in exam format before moving on

If your child is losing marks in HL organic chemistry, that is the single most common request we get in this subject, and it responds quickly to being taught systematically.

The Internal Assessment

A fifth of the grade, and the most controllable part of it.

Students most often lose marks on scope — a research question that cannot generate enough data — and on the evaluation section.

We coach the topic choice early, because a badly scoped question cannot be rescued in the write-up. Most IB schools provide lab access; where a student’s arrangement is different, we help design an investigation that works within it.

Across both levels

  • Full syllabus on the current Structure and Reactivity framework
  • Chemical language training — answers written the way the rubric marks them
  • Paper 1 data-based questions, which are routinely under-practised
  • Past papers from recent series, marked with written feedback
  • Internal Assessment coaching, research question to evaluation
  • Five to a class in Kovan, or one to one online

Questions

What parents ask.

What is the difference between IB Chemistry SL and HL?
Both cover the same Structure and Reactivity themes. Higher Level adds organic synthesis and mechanisms, spectroscopic identification, electrochemistry, entropy and spontaneity, and substantially more quantitative work. Both sit Paper 1 and Paper 2 — there is no Paper 3 under the current syllabus.
How is IB Chemistry different from A-Level or IGCSE Chemistry?
The content overlaps substantially with A-Level. The difference is the assessment: a compulsory Internal Assessment worth 20%, and a marking style that rewards very specific chemical language.
My child is struggling with organic chemistry at HL. Can you help?
Yes — it is the most common request in this subject. We teach it systematically rather than as a list to memorise: mechanism types first, then reaction pathways, then spectroscopic identification.
Does my child need lab access for the IA?
The IA requires a real investigation, and most IB schools provide lab access. We help scope an investigation that fits whatever access your child has, and coach the data processing and write-up regardless of where the experiment happens.
