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

### 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

It is true that the philosopher is the friend of wisdom, but above all, he is someone who does not want to make mistakes in reasoning. Philosophizing is a way of reasoning and a way of solving problems that will never have a perfect and definitive solution. Knowing the distance between the Earth and the Moon is not a problem of philosophy, because it is enough to measure to solve it. On the other hand, knowing, for example, what justice is, is a problem of philosophy. A meter will not be able to help us know the answer. We must go about it differently, and in the courses I offer, I will teach you how.

You will learn

- text reading strategies
- case studies with the aim of learning from experts
- methodology in philosophy
- writing an essay
- writing a text commentary
- a work on the philosophers of your choice
- an overview of the history of philosophy
- the general culture necessary to be able to philosophize

I will adapt to your individual needs. Each course is tailor-made. We will analyze where your difficulties lie and together develop a course program that will make you perform as quickly as possible. The basic principle of the courses I offer is dialectics, like Plato's dialogues: reflecting together, making theoretical contributions, asking questions and seeking answers, and testing the validity of reasoning.

For the past 10 years, I have been teaching German using the philosophy methodology, having studied philosophy at the Master's level at Aix-Marseille University. It turns out that the analytical mind is very useful even outside the confines of philosophy. Today, there are even fields of activity such as management with philosophy or philotherapy. In recent years, some German students have asked me to also teach them philosophy courses, and that is why I decided to offer philosophy courses directly.

I look forward to meeting you during a first lesson.

Ich studiere Computer Engineering an der RWTH Aachen und biete individuelle Nachhilfe in Mathematik, Physik und naturwissenschaftlichen Grundlagen an – von den ersten Grundlagen bis zur Oberstufe und zum Abitur.
Besonders wichtig ist mir, dass Schülerinnen und Schüler den Stoff wirklich verstehen, anstatt Formeln und Lösungswege nur auswendig zu lernen. Ich erkläre Zusammenhänge Schritt für Schritt, passe Tempo und Schwierigkeitsgrad individuell an und arbeite gezielt an den Stellen, an denen noch Unsicherheiten bestehen.
Wir können gemeinsam:
- aktuelle Themen aus dem Unterricht aufarbeiten,
- Hausaufgaben und Übungsaufgaben besprechen,
- Wissenslücken systematisch schließen,
- uns auf Klassenarbeiten, Klausuren oder das Abitur vorbereiten,
- und schwierige Themen mit zusätzlichen Aufgaben festigen.
In Mathematik kann ich unter anderem bei Algebra, Gleichungen, Funktionen, Geometrie, Trigonometrie, Analysis, Vektorrechnung und Wahrscheinlichkeitsrechnung helfen.
In Physik unterstütze ich unter anderem bei Mechanik, Elektrizitätslehre, Energie, Schwingungen/Wellen und weiteren schulischen Themen.
Durch mein Ingenieurstudium beschäftige ich mich selbst intensiv mit höherer Mathematik, Physik und technischen Anwendungen. Daher kann ich bei Bedarf auch fortgeschrittenere Schülerinnen und Schüler sowie Studienanfänger in mathematischen Grundlagen unterstützen.
Der Unterricht kann auf Deutsch oder Englisch stattfinden und wird individuell an das Niveau und die Ziele des Schülers bzw. der Schülerin angepasst.
Mein Ziel ist, dass Mathematik und Physik nicht mehr wie eine Sammlung zufälliger Formeln wirken, sondern Schritt für Schritt logisch und nachvollziehbar werden.

Hi, my name is Federica and I am an astrophysicist. I obtained my PhD from ETH Zürich and, for over ten years, I have been working in international research teams, contributing to space missions such as ESA Euclid and NASA Roman, and collaborating with scientists from all over the world.

For more than ten years, I have also been active in teaching, tutoring and science communication. In my teaching approach, I consider it essential to listen to the student, understand their needs, and identify the way they reason and learn best. This is key to creating a truly personalised learning path that motivates them to engage with the subject and gradually take on more advanced learning challenges.

I helped several students to strengthen the foundations, identify strategic points early, and progressively work towards more advanced problem-solving and exam preparation.

I do not believe in a standard “one-to-many” lesson, but rather in a learning path designed to genuinely consolidate the student’s knowledge, help them become progressively more independent, and make them aware of the practical and interdisciplinary applications that a particular subject can have in their academic journey.

I am fluent in Italian and English, and I am currently strengthening my knowledge of French. Thank you for your attention.
