What We Cover

Complete Cambridge IGCSE Chemistry curriculum coverage

Every topic aligned to the official syllabus. Every session taught with the mark scheme in view — not just content delivery but exactly how to demonstrate knowledge for maximum marks.

⚗️
Physical Chemistry
Atomic structure, bonding, stoichiometry, mole calculations, energetics, rates of reaction, equilibrium. Calculation questions require precise working that earns method marks even when final answers are wrong.
🧪
Inorganic Chemistry
Periodic table trends, metals, non-metals, acids and bases, salts, redox reactions. Cambridge tests qualitative analysis (identifying ions) consistently across all sitting sessions.
🔬
Organic Chemistry (Extended)
Homologous series, alkanes, alkenes, alcohols, carboxylic acids, esters, addition and substitution reactions. Organic is the most differentiating section in Extended tier — students who master it move from A to A*.
📊
Mole calculations
Empirical and molecular formulae, percentage yield, concentration calculations. These carry high marks in Papers 2 and 4 and are fully learnable with systematic practice.
📋
Paper 6 — Alternative to Practical
Planning experiments, identifying variables, processing results, evaluating procedures. Cambridge has precise expectation of format — our tutors teach it explicitly.
🌡️
Energetics
Endothermic and exothermic reactions, bond energies, enthalpy change calculations. Common source of lost marks in Extended Paper 4 when calculation method is not structured correctly.

Why Sev7n

Why students choose Sev7n for Cambridge IGCSE Chemistry

1
Mark scheme taught in every session
The most powerful thing a student can learn is exactly how examiners award marks. Not just what the right answer is — but how to present it, how much detail to give, which command term requires which response type. Sev7n tutors teach from mark schemes and examiner reports in every session.
2
Past paper coaching as the core method
Content knowledge is necessary but not sufficient. Students who practise past papers with real-time mark scheme feedback — session by session — build the examination fluency that produces grade improvement. Past paper work is central to every Sev7n session, not an add-on.
3
Sessions recorded on Sev7n LMS
Every session is saved to the student's personal dashboard. Students replay worked solutions, mark scheme walkthroughs, and examiner guidance as many times as they need — particularly valuable in the week before examinations.
4
48,000+ students across 30+ countries
Our tutors work with students in India, UAE, Singapore, the UK, the US, and across Europe. We understand the international examination landscape, the specific challenges faced by students at international schools, and the university pathways that follow from Cambridge IGCSE Chemistry results.

FAQs

Frequently asked questions — Cambridge IGCSE Chemistry

What is the difference between IGCSE Chemistry Core and Extended? +
Core tier targets grades C–G and covers fundamental chemistry concepts. Extended tier targets grades A*–E and adds significantly more content — particularly in organic chemistry, energetics, and quantitative analysis. Extended is required for students planning to continue to A Level Chemistry or IB Diploma Chemistry. Our tutors teach primarily Extended, though Core tutoring is available.
Is IGCSE Chemistry 0620 suitable for students planning Medicine? +
Yes — IGCSE Chemistry is the foundation for A Level or IB Diploma Chemistry, both of which are required for Medicine applications globally. Students planning Medicine should target A* at Extended tier and focus particularly on organic chemistry and quantitative calculations. Sev7n's Chemistry tutors are aware of this pathway and structure tutoring accordingly.
What does Paper 6 (Alternative to Practical) require? +
Paper 6 tests experimental planning, data collection, graph interpretation, and result evaluation — without requiring actual laboratory work. Cambridge has specific formats for how planning questions, table headings, and evaluation answers should be written. Most students who lose marks on Paper 6 do so because they have not been coached in these specific formats, not because they lack the chemistry knowledge.
How many hours of tutoring does a student typically need for IGCSE Chemistry? +
Students who start 4–5 months before exams and attend 2 sessions per week (approximately 32–40 hours total) typically improve by one full grade boundary. Students starting from a lower base or targeting A* from a B typically benefit from more intensive preparation. Our tutors assess your child's current level in the first session and give a realistic preparation timeline.
