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.

About me ✨
Hi — I’m Abanoub Ayad 👋. I come from a background in the cosmetics & pharmaceutical industries with 5 years’ experience, and I’m passionate about teaching chemistry. My biggest joy is turning the scary parts of chemistry into something clear, useful, and even fun for my students 🔬💡.

I’ve taught students across different curricula and levels, and I love helping learners build deep understanding and real exam confidence — not just memorization 📚✅.

What I teach 🧪
GCSE / IGCSE | A-Level (AS & A2) | IB | AP | American system (grades 7–12) | University-level General, Organic & Inorganic Chemistry

My lessons include 🎯
• Clear concept explanations — I make complex ideas simple.
• Worked examples + past-paper practice — real exam skills.
• Regular homework for reinforcement.
• Short quizzes at the end of each topic to check progress.
• Personalized study plans based on a diagnostic assessment.

Teaching style 🎓
Interactive, patient, and tailored. I use diagrams, mnemonics, and real-life examples to help memory and intuition. I also bring in data-driven methods (I use statistical tools when helpful) to track improvement and focus on weak spots 📈🧠.

Policies & what I don’t do 🚦
• I won’t complete exams or homework for you — I’ll teach you how to do them.
• I provide clear feedback and practice so you can succeed independently.

Why choose me? 🌟
I care about each student’s goals — whether that’s boosting grades, preparing for admissions, or building real scientific understanding. Book your first lesson and let’s make chemistry a subject you enjoy and succeed at! ☕🧪🙌
