IGCSE Chemistry Tutor Online (0620)

IGCSE Chemistry rewards two things above all: writing balanced equations correctly, and handling moles confidently. Students who are secure in both find the rest of the syllabus manageable. Students who are shaky in either lose marks in every topic, because both run through the whole course.

The Three Foundations

Balanced equations

Not a topic, a skill used constantly. Weakness here surfaces as apparently unrelated errors across the paper.

Moles

The concept that unlocks stoichiometry, titration calculations and much of quantitative chemistry. It is the single highest-return topic to fix.

Practical and analysis

Salt analysis, tests for ions and gases, titration technique and the alternative-to-practical paper. Highly patterned, easy to prepare, routinely neglected.

Where IGCSE Chemistry marks actually go

Equations left unbalanced or with state symbols missing where they are required.
Mole calculations attempted without units, or with the wrong molar quantity.
Observation questions answered with conclusions rather than observations — “a white precipitate forms” scores; “it is a chloride” often does not, where an observation was asked for.
Organic chemistry memorised as isolated facts rather than as a homologous-series pattern.

What Separates a Good Ivy League Application From a Great One?

Our counsellors help you shape your profile, strengthen your essays, and present your achievements with a clear, authentic story, not a checklist of activities.

Student testimonial

frequently asked questions

Less than students assume. Most of what looks like memorisation is pattern — the periodic table, homologous series, reactivity trends. Teaching the pattern reduces the load substantially.

Yes, and quickly, because it is a single well-defined skill. It usually takes three to four focused sessions, and the improvement then shows up across several topics.

We teach the practical component directly — tests for ions and gases, titration technique, observation recording and the alternative-to-practical format.

Yes, at every subsequent stage. A student targeting medicine should be on Extended Chemistry and planning for A Level or IB HL Chemistry.

One to two through Grade 10, more before mocks.
