Chemistry Calculations Masterclass | IGCSE & IB ### Master Chemistry Calculations and Maximize Your Exam Marks Do you understand Chemistry theory but struggle when you face calculation questions? Do you lose marks because of **formula selection, unit conversions, mathematical steps, significant figures, or poorly structured working**? This masterclass is designed specifically for **IGCSE and IB Chemistry students** who want to build strong confidence in quantitative Chemistry and improve their exam performance. I’m **Dr. Basil**, a Chemistry tutor with **10+ years of experience teaching international curricula**, including IGCSE, IB, GCSE, A-Level, and American Chemistry. With a background in Pharmacy and Quality Management, I use a systematic, step-by-step approach that helps students understand not only *how* to calculate the answer, but *why* each step is required. ### What You Will Master **Core Quantitative Chemistry – IGCSE & IB** • The mole concept and Avogadro's constant • Relative atomic mass and relative formula mass • Molar mass calculations • Balanced equations and stoichiometric calculations • Limiting reactants • Percentage yield and atom economy • Empirical and molecular formulae • Gas volume calculations • The ideal gas equation • Concentration calculations • Dilution calculations • Titration calculations • Reacting masses and volumes **IB Chemistry – Additional Skills** • Uncertainty calculations • Percentage uncertainty and percentage error • Significant figures and decimal places • Data processing and evaluation • Uncertainty in experimental results ### How We Work Rather than simply memorizing formulas, you will learn a **repeatable method for solving Chemistry calculations**: **Understand → Identify → Choose the equation → Substitute → Calculate → Check → Give the correct units** We will work through progressively more challenging problems and use **IGCSE/IB-style exam questions and past papers** to develop speed, accuracy, and exam technique. ### This Masterclass Is Ideal For Students Who: ✓ Struggle with Chemistry calculations ✓ Understand the theory but cannot apply it to questions ✓ Make frequent calculation or unit-conversion errors ✓ Find stoichiometry and mole calculations difficult ✓ Need help with titration and concentration problems ✓ Want to improve their exam technique ✓ Are preparing for IGCSE or IB Chemistry exams ✓ Want structured practice and targeted feedback ### What You Can Expect ✓ Clear, step-by-step explanations ✓ Personalized instruction based on your current level ✓ Extensive calculation practice ✓ Exam-style questions and past-paper practice ✓ Identification and correction of recurring mistakes ✓ Guidance on showing working clearly to earn method marks ✓ Strategies for checking whether your answer is reasonable ✓ Focused preparation for IGCSE and IB examinations **The goal is not simply to memorize Chemistry formulas — it is to develop the confidence and problem-solving skills to approach unfamiliar calculation questions successfully.** Book a lesson and let's turn Chemistry calculations from a source of lost marks into one of your strongest areas.
