Cambridge IGCSE Chemistry 0620: the three papers

The 0620 syllabus covering 2026 to 2028 came out as version 2 in August 2026; Cambridge describes the revision as making no substantial difference to teaching. Each candidate takes three components:

The Core route can lead to grades C to G, the Extended route to A* to G, and anyone likely to earn a C or higher belongs on Extended. Cambridge weights the whole qualification at one half for knowledge and understanding, three tenths for handling information and solving problems, and one fifth for experimental skill.

The twelve topics, grouped for revision

A mole routine that lasts from Grade 9 to DP2

Able Extended candidates lose a grade on the theory paper more often through stoichiometry than anything else, and it is equally the topic where extra teaching shows results soonest, since a single routine handles almost every question:

• Equation first. Balance it; the ratio between substances comes from here and nowhere else.
• Into moles. Convert what you are given (a mass, a volume of gas, or a concentration with a volume) after fixing the units.
• Across the ratio. Use the balanced equation to get moles of the substance you want.
• Out of moles. Turn the answer into whatever form the question asks for.
• Sense check. Are the units right, are the significant figures sensible, and is the number plausible?

Drilled from the opening term, this makes percentage yield, purity and titration problems ordinary by Grade 10, and the DP course then builds on ground that is already solid.

Paper 5 or Paper 6 without chemicals at home

In Cambridge's view the hands-on and written practical papers assess one set of skills in one set of situations; the only difference is whether students do the experiment or read about it. Each paper prints notes for qualitative analysis, which spares students from learning every test by heart, though they still need to find the right line fast and describe what they see in Cambridge's terms. Worth rehearsing: precise readings of volume, mass, temperature and time; burette reading and when titres count as concordant; describing colour changes, precipitates and gas tests; planning an experiment with its variables, controls, equipment and hazards; and picking out results that do not fit. Since chemicals stay in the school lab, home sessions use genuine past practical questions, apparatus sketches and repeated practice of the observation wording.

IB DP Chemistry: structure and reactivity

Since its first assessment in 2025, the IB course has been organised around two linked strands. The IB recommends 150 teaching hours at SL and 240 at HL.

A student used to separate physical, inorganic and organic chapters may feel lost at first. It helps when the tutor names the links aloud, for instance how a functional group met under Structure 3 predicts the reaction types studied under Reactivity 3.

How DP Chemistry is examined

Students have a calculator and the data booklet for both papers, and guessing on multiple choice carries no penalty. In Paper 1B the stimulus might be a titration curve, a rate graph or a table of enthalpy data the student has never seen, followed by calculations with uncertainty and suggestions for a better method. Paper 2 marks are usually lost on equations that do not balance, state symbols left off, curly arrows drawn to the wrong atom, and trends described with no explanation. HL goes deeper in most topics, and its 90-mark Paper 2 needs timed practice to build stamina.

The IB investigation: what a tutor may and may not do

SL and HL students complete the same internal assessment: a research question of their own, quantitative data they collect and analyse, and a report capped at 3,000 words. Four criteria (research design, data analysis, conclusion, evaluation) carry six marks each. Good chemistry IAs tend to be tightly focused: a single variable changed, a single outcome measured, and enough readings to reveal a trend together with its uncertainty.

• Allowed: explaining what each criterion looks for; helping the student check that an idea is safe and possible with school equipment; teaching the underlying chemistry; and building graphing, error analysis and uncertainty skills long before the IA period.
• Not allowed: selecting the question, planning the method, working on the data, or drafting or correcting the write-up. Under the IB's academic-integrity rules that would endanger the diploma, and the school's supervisor must confirm the work is the student's.

From Grade 10 to DP1, and choosing the level

Good Extended mole work is a sound base, though the DP picks up speed on amounts of substance almost at once. Bonding grows from dot-and-cross diagrams into shapes, polarity and forces between molecules, and handling data with uncertainty, a minor theme at IGCSE, becomes central. Students set on medicine, chemistry or chemical engineering who are comfortable with numbers usually choose HL; those who need a science alongside other priorities often choose SL. A short bridging block in the holiday before DP1 makes the first weeks calmer. Anyone moving from Cambridge to an Indian board for Class 11, including the State Board's +1, will find the Class 11 chemistry tutor page more relevant.

How chemistry tutors reach homes across Chennai

Specialists for the international chemistry papers are fewer than tutors for the Indian boards, so the journey matters:

• Velachery, Guindy and Tambaram. Velachery has had an MRTS station since 2007, and the line now runs on to St Thomas Mount; avoid lesson times that collide with the Vijayanagar junction rush. Further south, Tambaram is one of the area's main railway terminals, so tutors from Chromepet or Perungalathur can come by train, with an auto for the last stretch.
• Anna Nagar, Kilpauk and Aminjikarai. Anna Nagar has three underground Green Line stations, and the numbered avenues make homes easy to find.
• Vadapalani, KK Nagar and Porur. KK Nagar's sectors and streets are numbered, and Ashok Nagar on the Green Line is the nearest metro.
• Perambur, Kolathur and North Chennai. Perambur has three suburban stations on the line towards Avadi and Arakkonam; Royapuram, whose 1856 station still has suburban trains, has narrow lanes and little parking, so train, bus or auto is the easier way in.

All localities are on the Chennai home tutors page, and the south Chennai and west and north Chennai tuition guides give more on travel.

Home or online for IB and IGCSE chemistry

Drawing mechanisms, structures and practical apparatus is easiest side by side at a table. Data questions, marking against the scheme and talking through an IA idea work just as well over video, and going online opens up specialists from beyond your part of the city when nobody nearby knows the course. A common Chennai arrangement is one lesson at home and one online each week, both with the same tutor, so a slow evening on the roads never wipes out a week.

What to check in the chemistry demo

1. Before teaching, did the tutor pin down the course: 0620 at Core or Extended with Paper 5 or 6, or the DP at SL or HL?
2. For DP students, are lessons framed in the Structure and Reactivity strands, not the old chapter list?
3. Are official mark schemes, Cambridge or IB, used every week?
4. Watch them lay out a mole problem: would your child be able to copy that layout?
5. Do they set out the limits on investigation help before you raise it?
6. What is their route to you, and what time of day can they reliably arrive?

Not convinced after the demo? Let us know, and another matched tutor will give a free demo of their own.

Fees and getting started

Across NXTutors, most home-tuition sessions fall between ₹800 and ₹2,500 an hour; Classes 11–12, IB/IGCSE and JEE/NEET sit toward the upper end; specialists for IB HL or JEE Advanced can charge more. Tutors price their own sessions, and the figure is on the profile before any demo. The pricing guide and our Chennai tuition fees post explain what changes it.

Write to us with the course, the grade or DP year, the topics that worry you, your locality and nearest station, and the hours that suit. Two or three tutors are shortlisted; one teaches a free demo class, and changing later costs nothing. An ID check is part of joining for every tutor. You can also look at tutor profiles, our national chemistry page, and Chennai pages for IB physics and IGCSE physics.
