IB Chemistry HL in brief
IB Chemistry HL is often required for Medicine, Dentistry, Pharmacy, Biomedical Sciences and Chemical Engineering at many universities, and is recognised by NUS and NTU as the IB equivalent of H2 Chemistry. The syllabus covers stoichiometric relationships, atomic structure, periodicity, chemical bonding and structure, energetics and thermochemistry, chemical kinetics, equilibrium, acids and bases, redox processes, organic chemistry, measurement and data processing. The current syllabus, first examined in 2025, is organised into Structure and Reactivity, with extra HL content and no option topics. Assessment is Paper 1 (1A multiple choice and 1B data-based questions), Paper 2 (short-answer and extended-response) and the Internal Assessment, a scientific investigation worth 20 percent of the final grade.
Read the full guide
Our IB Chemistry HL tutors run a structured DP1 to DP2 programme. The DP1 syllabus covers stoichiometric, atomic structure, periodicity, bonding, energetics, kinetics, equilibrium, acids and bases (HL depth). The DP2 syllabus then layers redox, organic chemistry advanced topics and the IA execution. Each tutor's own qualifications and teaching experience are shown on the shortlist.
The IB Chemistry HL IA can be a demanding internal assessment, partly because the chemistry-specific safety constraints limit what students can investigate at home. Common topic mistakes include picking an investigation that requires unsafe reagents, an outcome that is not quantitatively measurable, or a research question too vague to operationalise. Our tutors steer students toward IA topics that satisfy the rubric while staying inside school-lab safety limits: kinetics studies via colorimetry, equilibrium constant determination via titration, electrochemistry via standard electrode potentials, or food chemistry investigations using widely available reagents.
We coach the methodology section to include uncertainty propagation, the analysis section to include error bars and statistical comparison, and the evaluation section to identify systematic and random error sources separately. The IA carries 20 percent of the final grade, so this planning is worth doing early.

IB Chemistry HL tuition rates
Real ranges by level and tutor tier. We re-match free if the fit is wrong.
| Level | Part-time / undergrad | Full-time | Ex-MOE or NIE-trained |
|---|---|---|---|
| IB Diploma (DP1-DP2) / IGCSE | S$60-80/hr | S$75-110/hr | S$95-150/hr |
Final rate is set on tutor match and depends on tutor tier, level and lesson frequency. See full pricing page.
Common IB Chemistry HL Struggles We Fix
IB Chemistry HL marks at the 6 and 7 grade levels are decided on Paper 2 extended-response and the Internal Assessment. The patterns we see most often:
Equilibrium and Ka, Kb, Kw calculations break down on multi-step ICE-table questions.
Organic chemistry mechanisms (electrophilic addition, nucleophilic substitution) are confused under exam pressure.
Paper 1B data-based questions are unfamiliar in style.
Internal Assessment investigation design lacks a clear research question or sufficient mathematical content.

HL-only extension content is undertaught at the home school.
Extended-response answers are conceptually correct but use wrong vocabulary, losing marks to keyword penalties.
These are the gaps our IB Chemistry HL tutors fix with structured DP1 to DP2 sequencing and dedicated IA coaching.

Why parents pick us
IB DP-Specialist Tutors
Our IB Chemistry HL tutors teach to the IB curriculum, marking criteria and IA expectations.
Dedicated IA Coaching
The Internal Assessment is 20 percent of the final grade. We coach research question design, mathematical content depth, and the rubric criteria across DP1 and DP2.
Option Topic Coverage
The current syllabus has no option topics. We match tutors who teach the Structure and Reactivity framework first examined in 2025.

IB Chemistry HL: frequently asked questions
What does IB Chemistry HL cover?
The IB Chemistry HL syllabus spans stoichiometry, atomic structure, bonding, energetics, kinetics, equilibrium, acids and bases, redox and organic chemistry, with additional HL depth.
How is IB Chemistry HL assessed?
Written examination papers plus the internally-assessed investigation (IA). The IA rewards a well-designed, well-analysed practical investigation.
How does IB Chemistry compare to A-Level H2 Chemistry?
Both are rigorous. IB includes the IA coursework component and a broader syllabus, while H2 is exam-focused. The right comparison depends on the student's school.
IB Chemistry HL is Often Required for Medicine and Dentistry
IB Chemistry HL is commonly expected for Medicine, Dentistry, Pharmacy and Biomedical Sciences courses.
