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

### 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.
