Chemistry Calculations Masterclass ( IGCSE & IB )
Van 28 $ /h
From Confusion to Full Marks in Quantitative Chemistry
This masterclass is designed for IGCSE and IB Chemistry students who struggle with calculations and want to gain complete confidence in quantitative problem-solving.
Many students understand theory but lose significant marks in exams due to calculation errors, weak formula application, or poor structured working. This course focuses exclusively on mastering the mathematical and logical framework required for high exam performance.
With over 10 years of teaching experience and a background in Pharmacy and Quality Management, I provide a systematic and structured approach that transforms calculation weaknesses into strengths.
What This Course Covers
Core Topics (IGCSE & IB)
The mole concept and Avogadro’s constant
Relative atomic mass and molar mass
Stoichiometry and balanced equations
Limiting reagent calculations
Percentage yield and atom economy
Empirical and molecular formula determination
Gas volume calculations and ideal gas law
Concentration (mol/dm3), dilution, and titration problems
Uncertainty and percentage error (IB focus)

Areas of Specialization
IB Chemistry (HL & SL)
IGCSE Chemistry (Cambridge & Edexcel)
IB Internal Assessment (IA) supervision
Organic Chemistry
Stoichiometry and quantitative problem-solving
Exam preparation and past paper practice
Laboratory data analysis and evaluation writing
My methodology is structured, systematic, and results-oriented.
Many students struggle not because they lack intelligence, but because they lack a clear strategy. I train students to:
Understand concepts at a fundamental level
Apply knowledge to unfamiliar exam questions
Analyze mark schemes effectively
Improve calculation accuracy and time management
Structure answers according to examiner expectations
For IB students, I provide guided support in formulating strong IA research questions, data processing, uncertainty analysis, and evaluation writing.
