Chemistry for High School and University exams (English)

From 56 C$ /h

This class will help my students (from high school to university level) to understand and face one of the most studied discipline in science: chemistry. I have been worked with tens of students, in Italian and in English, helping them for university exams and for high school tests. The class is structured depending on the students needs, with both theoretical and practical (exercises) study. Typical topics in general chemistry are: pH, titrations, redox, stochiometry, electrochemistry. But there is much more.
Together we can have fun with chemistry!

About Me

Hi everyone,
I am a PhD student in Physical Chemistry working in the solar field and renewable energies. I have been teaching for six years now, both when I was a student in Italy and now in Amsterdam. If there is something that I know for sure is that I want to become a professor one day as the most satisfying thing for me is to know that my students appreciate and have fun chemistry after my lessons. Chemistry is not so bad after all!

Chemistry Class (pH, electrochemistry, titration, redox, stoichiometry) - English

53 C$ /h

Chemistry is a widespread subject in many schools, institutes and universities.

The first obstacle to overcome this subject is quantitative chemistry, an enormous examination full of notions such as pH, electrochemistry, titrations, redox, atomic and molecular orbitals, colligative properties, gas. I offer lessons on all these topics, both for exam preparation and for a test or class assignment.

I combine theory with practice, offering exercises I propose or carrying out those that you bring yourself.

I am Mavi, a physics engineer working at an aerospace company.
I have been teaching private lessons at the primary, secondary, high school, and university preparatory levels for 11 years. I teach mathematics, physics, chemistry, and science. I have a good command of the curricula of IB, IGCSE, American, Hong Kong, and international schools.

Additionally, I hold the position of president at the Astronomy Society, where I foster my students' interest in astronomy and science beyond the lessons. I prepare the learning environment by incorporating experiments and exploration, moving away from rote education. I often bring experimental materials to class, aiming to make learning memorable through hands-on experiments.

As an educational mentor, I approach my students as if they were my siblings, valuing creativity. I have a deep passion for mathematics, physics, and science. I am dedicated to helping students understand and learn because life encompasses both SCIENCE and ART. The more people I can inspire to know, understand, and love mathematics, physics, and chemistry, the more proud I am.

Are you curious about how nature works?

I offer clear, structured tutoring in Mathematics, Chemistry, and Physics, supporting students with both content mastery and exam success at Advanced Subsidiary and Advanced Level (AS and A-Level), for both Edexcel and Cambridge. My lessons focus on clear explanations and the core ideas behind each topic, so things actually make sense.

For exam preparation, I shift focus to exam technique: you'll learn how mark schemes work, how answers are graded, and how to phrase responses clearly so you don’t lose marks because of wording, even when you know the content.

Having worked with over 100 students across various international curricula, I provide a high-level, integrated approach to the core STEM subjects: Mathematics, Physics, and Chemistry. My lessons are tailored to the specific mark schemes and requirements of IGCSE, GCSE, and the IB Diploma (SL/HL).

Mathematics: From IGCSE Extended/Additional Math to IB Math AA/AI (HL & SL). We focus on logic, function analysis, and the critical "investigative" style of exam questions.
Physics: Mastering the laws of physics, from Mechanics and Waves to Electromagnetism and Atomic Physics, with a heavy focus on the mathematical application of formulas.
Chemistry: Bridging the gap between theory and the lab. We cover everything from Atomic Structure and Stoichiometry to Organic Chemistry and Energetics.

Because I teach all three, I help students see the connections, like the math in Physics or the physics in Chemistry, making the entire STEM workload feel more cohesive and less overwhelming.

I provide the clarity needed to handle the high volume of material in these curricula, ensuring students are not just "studying," but are strategically prepared for top-tier grades (9s in IGCSE or 7s in IB).

Chemistry is concerned with the physical and chemical properties of substances and the interaction of
energy and matter. The study of Chemistry involves an investigation into chemical reactions and
processes. The discipline seeks to explain and predict events at the atomic and molecular level.
Through the principles of Chemistry, students will understand everyday life, nature and technology, and
the significance of the well-being of man and the environment.

Biology is the discipline in science which seeks to understand the organisation of the organic world
through an exploration of the structure and function of life forms at the molecular, cellular, organismal
and ecosystem levels, as well as the complex interactions and interdependencies which occur at each
of these levels. This knowledge provides the foundation for understanding the opportunities for
promoting the well-being of humans and other living organisms in the environment. It generates an
awareness of the importance of our biodiversity and the unique role of humans in conserving,
protecting and improving the quality of the biological environment for future generations.

How the lessons work

Before the lesson, students can share their textbook chapter, syllabus, worksheet or difficult topic. This allows me to prepare a lesson that directly matches what they are studying in school.

A typical lesson includes:

A short review of previous knowledge
A clear explanation of the main concept
Diagrams, examples and everyday applications
Guided practice questions
Independent questions to check understanding
Correction of mistakes
A brief summary and revision task

I do not simply provide answers. I help students understand why an answer is correct and how to solve similar questions independently.

Homework and examination support

I can help students with:

Understanding homework questions
Revising difficult chapters
Practising multiple-choice questions
Solving science calculations
Preparing short and long answers
Reading and interpreting diagrams
Understanding scientific experiments
Preparing for school tests and final examinations
Creating a manageable revision plan
Identifying and improving weak topics

I provide guidance and feedback while encouraging students to complete their own assessed work.
