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 Magdi**, 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.

Demonstrating a genuine passion for science can be contagious. When children see that their teacher is enthusiastic about the subject, it can ignite their own curiosity and interest in science. Moreover, being able to explain complex scientific concepts in a simple and engaging manner is a crucial skill for a science teacher. Parents want someone who can make science understandable and exciting for their children.

I am a dentist so I have a solid background in the medical field. I am very passionate about teaching that’s why I have been tutoring all the sciences related subjects from the beginner level to the advanced level for two years. I was a previous IGCSE student so I am fully aware by the British Curriculum and have a good experience in it. I have a diploma in the psychological management of Children and I do believe that teaching is not only about conveying the academic curriculum, but also taking care of the psychological state of mind and character development of the students.
