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.

I'd like to start by greeting everyone who is reading this and then briefly discuss the teachings I'm providing. Going to medical school is a major step, and while becoming a doctor may have been a big dream of yours, things unfortunately didn't turn out the way you had hoped. You didn't receive what you eagerly want following your bac. I'm here to tell you that earning your bac is just the first step on a longer journey. You have another opportunity to fulfill your lifelong ambitions. What role do I play in this? as someone who has been in your position and ultimately obtained what I want. We will have a customized plan that fulfills your needs, we will correct any unsuccessful methods and build new ones, and I will lead you through the program at every stage.

As a dedicated tutor with extensive experience in preparing students for standardized exams such as the SAT, GMAT, and SSAT, I understand the unique challenges that each of these tests presents. My approach is comprehensive and focuses on building a strong foundation in critical areas such as Mathematics, Quantitative Reasoning, Verbal Skills, and Analytical Writing. Each program I develop is tailored to the specific requirements of the exam, ensuring that students are well-prepared and confident on test day.

Having a deep understanding of the test formats and question types allows me to provide personalized strategies that target each student's individual strengths and weaknesses. I believe that every student has a unique learning style, and my goal is to enhance their test-taking skills while improving their time management. By fostering a supportive learning environment, I aim to boost students' confidence and empower them to achieve top scores.

My tutoring sessions incorporate a variety of effective methods, including real exam questions and timed practice tests. This hands-on approach allows students to familiarize themselves with the types of questions they will encounter, making the actual exam feel less daunting. I teach proven techniques for tackling even the most challenging problems, ensuring that students feel equipped to handle any question that comes their way.

One of the key components of my tutoring is helping students develop effective study habits. I provide guidance on creating a structured study plan that maximizes their preparation time and aligns with their personal goals. This structured approach not only keeps students on track but also helps them build a sense of accountability, which is crucial for success.

In addition to academic preparation, I also focus on the psychological aspects of test-taking. Many students experience anxiety leading up to exams, which can affect their performance. I teach relaxation techniques and mental strategies to help manage stress, allowing students to approach their exams with a calm and focused mindset. By addressing both the academic and emotional challenges of test preparation, I equip students with a well-rounded toolkit for success.

Feedback is an essential part of the learning process, and I make it a priority to provide constructive and actionable insights during our sessions. After each practice test, I conduct a thorough review of the results, highlighting areas for improvement while also acknowledging progress. This continuous feedback loop helps students understand their growth and keeps them motivated throughout their preparation.

My commitment to student success goes beyond just teaching content. I aim to inspire a love for learning and self-improvement in each of my students. Many of my former students have gone on to achieve their academic goals, securing places at prestigious universities and programs. Their success stories are a testament to the effectiveness of my tailored approach and the dedication I bring to each tutoring session.

If you're looking to master the SAT, GMAT, or SSAT with confidence, I invite you to book a session now. Together, we will develop a customized learning plan that suits your individual needs, ensuring that you are not only prepared to face the test but also equipped to excel and reach your highest potential. With my guidance and your commitment, we can achieve outstanding results. Let’s embark on this journey to success together!

My name is Emilie and I am a veterinary medicine student. I also hold a Master's degree in health technologies and have almost 10 years of experience in the pharmaceutical industry, including some time in a training-oriented role.

This experience has taught me to make sometimes complex concepts clearer, more structured and accessible, but also to adapt to very different learning styles. Some students need a diagram, a concrete example, to rephrase things aloud, or simply to proceed step by step.

Patient, organized, and attentive, I aim to provide a supportive environment where students can ask questions without fear of making mistakes. My goal is to help them progress, gain confidence, and acquire methods they can then use independently.

I primarily offer academic support from middle school to the final year of high school, particularly in science subjects, as well as English tutoring.
