Cambridge IGCSE Chemistry 0620: the three components

Cambridge put out a second version of the syllabus for the 2026 to 2028 series in August 2026, stating that nothing in it substantially alters teaching. A candidate's grade is assembled from three pieces:

Core opens grades C to G and Extended A* to G; a student expected to achieve C or higher belongs on Extended. Knowledge with understanding carries half the weight across the qualification, handling information and problem-solving 30 percent, and experimental skills the last 20.

The twelve topics, grouped for revision

Cambridge lists twelve topics. Grouping them makes a revision plan easier to follow:

• Building blocks: states of matter; atoms, elements and compounds; stoichiometry. Watch for weak dot-and-cross diagrams and, on Extended, shaky work with moles, concentrations and gas volumes.
• Energy and change: electrochemistry; chemical energetics; chemical reactions. Electrolysis products and half-equations, energy-level diagrams, and rates and equilibrium cause the most trouble.
• Families of substances: acids, bases and salts; the Periodic Table; metals; chemistry of the environment. Choosing the right method to make a salt, writing ionic equations, and linking reactivity to extraction are the usual weak spots.
• Carbon and the laboratory: organic chemistry; experimental techniques and chemical analysis. Naming compounds, recognising reaction types, chromatography and Rf values, and the tests for ions and gases.

Mole calculations: one method from Grade 9 to the DP

Ask Extended candidates where Paper 4 went wrong and the answer is very often a moles question. The good news is that the same short routine solves almost all of them, so tutoring pays off quickly here. We teach five moves in a fixed order: get a balanced equation, because the ratio comes from it; change the quantity you are given (a mass, a solution's volume and concentration, or a volume of gas) into moles, sorting out units first; use the ratio; change the answer back into what was asked; and finally ask whether the units, the number of significant figures and the size of the result make sense.

A student who drills that routine from Grade 9 handles percentage yield, purity and titrations calmly in Grade 10, and arrives in the Diploma with the footing its chemistry takes for granted.

Getting ready for Paper 5 or Paper 6 without chemicals at home

Paper 5 is done at the bench and Paper 6 on paper, but Cambridge assesses the same skills in each. Qualitative analysis notes are printed inside both papers. That spares students from learning every ion test by heart; it does not spare them from finding the right line fast and writing down what they see in the words examiners look for. Worth practising: measuring masses, volumes, temperatures and times to sensible precision; burette readings and deciding which titres are concordant; describing colour changes, precipitates and gases; planning an experiment with its variables, controls, equipment and safety points; and picking out an anomalous result.

None of that needs chemicals at home, and nobody should try experiments on a kitchen counter in a Vasundhara flat. Past practical questions, apparatus drawn together, and observation words used until they come naturally are what a tutor adds.

DP Chemistry: structure and reactivity

Since the 2025 exams, the IB has arranged the whole subject under two linked ideas. HL is planned for 240 teaching hours and SL for 150. Structure runs from models of particles (the nuclear atom, electron configuration, amounts in moles, ideal gases) through ionic, covalent and metallic bonding to materials, and then to classifying matter by the periodic table and by functional group. Reactivity asks three questions in turn: what makes a reaction go, answered with enthalpy and energy cycles plus entropy and spontaneity for HL; how far and how quickly it goes; and by what mechanism, whether protons, electrons or electron pairs are transferred or shared.

A student brought up on "physical, organic, inorganic" chapters may feel lost in this arrangement at first. It helps when the tutor keeps naming the links, such as the line from functional groups on the Structure side to reaction types on the Reactivity side, until the course reads as a single story.

How DP Chemistry is examined

Students have the data booklet and a calculator in both papers, and a wrong multiple-choice answer costs nothing. Paper 1B asks students to interpret an unfamiliar titration curve, rate graph or table of enthalpy data, calculate with uncertainties and suggest improvements. Paper 2 punishes small carelessness: an equation that does not balance, state symbols left off, curly arrows drawn from the wrong place, a trend named but never explained. At HL nearly every topic goes deeper, and the longer Paper 2 is as much a test of stamina as of knowledge, so timed practice matters.

The DP investigation: helpful support and its limits

The internal assessment is identical at both levels. The student asks a question of their own, gathers and analyses numerical data, and writes it up in no more than 3,000 words; four criteria (how the investigation was designed, how the data were analysed, the conclusion, and the evaluation) carry 6 marks each. The chemistry investigations that do well are usually tightly focused: a single variable changed, a single outcome measured, and readings enough to show a trend with its uncertainty.

• Within the rules: going through the criteria; helping the student check that an idea is safe and can be done with what the school lab has; teaching the underlying chemistry; and, long before the investigation starts, teaching how uncertainties combine, how to graph and how to discuss errors.
• Outside the rules: deciding the question, planning the method, working on the data, or drafting or editing the write-up. Doing any of these breaches IB academic-integrity rules, and the school's supervising teacher signs off the work as the student's.

Moving from 0620 to the Diploma, and choosing the level

A secure Extended grade in moles is a sound start, yet the Diploma covers amounts of substance at a much quicker pace. Bonding no longer stops at dot-and-cross: molecular shape, polarity and the forces between molecules all follow. Uncertainty in data, barely touched at IGCSE, runs through the whole course. HL is the natural choice for future doctors, chemists and chemical engineers who like calculation; SL fits a student who needs a science but whose main subjects are elsewhere. Some bridging work in the holiday before DP1 takes the edge off the first term. If your child is leaving Cambridge for a Class 11 board course, the national Class 11 chemistry page is the better guide.

How chemistry tutors reach different parts of Ghaziabad

From our zone research:

• Indirapuram. Gyan Khand 4 mixes houses, builder floors and complexes, reached from Vaishali or Noida Electronic City by e-rickshaw; the arterial roads jam at rush hour. Nyay Khand 2 sits on Kala Pathar Road, which is busy at office and school-return times, so a slot just after the peak saves waiting. In Shakti Khand 2, Noida Electronic City is the closest station and CISF Road is heavy at peak hours.
• Vasundhara. Sector 5 is nearest Mohan Nagar on the Red Line, but not within walking distance, so tutors take an e-rickshaw or come by scooter.
• Sahibabad and Rajendra Nagar. Shalimar Garden Extension is mostly independent floors; tutors usually come to Raj Bagh on the Red Line and take an auto along Wazirabad Road, which slows at school and evening rush hours.
• Raj Nagar, Kavi Nagar and Old Ghaziabad. Nandgram is near the Hindon River and Shaheed Sthal Red Line stations and within reach of the Ghaziabad and Guldhar Namo Bharat stations; the inner lanes are narrow at peak hours, so early-evening or weekend lessons are easier to keep.

Every locality is on the Ghaziabad home tutors page. Mole work, mechanisms and practical-paper drawings go well at the table; Paper 1B data questions and markscheme review work well online. When the only HL chemistry specialist lives across the city, one home and one online session a week is a common arrangement. Our home versus online guide covers the trade-offs.

Six things to notice during a chemistry demo

1. Before teaching, does the tutor establish 0620 or DP, tier or level, and the series or session?
2. Can they show a mole calculation laid out in clear steps, with units?
3. For IGCSE, do they know whether your school uses Paper 5 or Paper 6, and how each is marked?
4. For the DP, can they explain how the Structure and Reactivity headings connect?
5. Are they clear about what they will and will not do for the investigation?
6. Is their route to you realistic on a weekday evening?

The demo class checklist adds general questions.
