Maths, Physics or Chemistry Lessons (High School/Secondary)

From 67 C$ /h

With 5+ years of experience teaching students in international schools (IGCSE, GCSE, A-level, IB), I offer clear, structured tutoring in Mathematics, Chemistry, and Physics. My lessons focus on clear explanations and the core ideas behind each topic, so things actually make sense, which helps students with both content mastery and exam success.

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.

I am a physicist and PhD researcher at the University of Geneva, with several years of experience teaching physics at university level and providing private tutoring in physics, mathematics and chemistry.

My academic background includes degrees in Physics and Solid-State Physics, as well as a background in Industrial Chemistry. This allows me to teach science subjects from secondary-school level up to university courses, while adapting the level of explanation to each student.

I can help with:

* Physics: mechanics, electricity and magnetism, waves, optics, thermodynamics, modern physics and introductory quantum physics
* Mathematics: algebra, functions, calculus, trigonometry, vectors and problem solving
* Chemistry: general chemistry, physical chemistry and introductory university chemistry
* IB, Maturité and international-school programmes
* University physics and mathematics courses
* Exam and mock-exam preparation
* Revision of previous-year material
* Homework, exercises and problem-solving techniques

My approach is based on understanding rather than memorisation. I first identify where the difficulty comes from, then rebuild the relevant concepts step by step before applying them to exercises and exam-style problems.

Because I also teach university students, I place particular emphasis on developing a clear method: how to interpret a problem, identify the relevant physical principles, organise a calculation and check whether the final result makes sense.

Lessons can be adapted either for students who are struggling and need to rebuild their foundations, or for stronger students preparing for demanding exams and advanced courses.

I teach in English, French and Italian.

Online lessons and in-person lessons in the Geneva area are available.

Swiss-Focused Mathematics, Physics & Chemistry Tutoring – Passerelle, BMS, Berufsmaturität, Matura, Fachmaturität, QV & Adult Education

This class is designed for students and adult learners in Switzerland who want serious, structured and exam-focused support in Mathematics, Physics and Chemistry. The main focus is preparation for Passerelle, BMS, Berufsmaturität, Matura, Fachmaturität and QV/final apprenticeship exams, as well as support for learners in adult education who are returning to study, changing career direction or preparing for a new academic path.

What makes my tutoring different is the strong connection to the Swiss education system. I completed my master’s degree at a University of Applied Sciences in Switzerland and have many years of experience teaching students in Switzerland. This means my lessons are not generic international tutoring. They are built around Swiss school expectations, Swiss exam styles, Swiss curricula and the specific challenges faced by learners in Switzerland.

➜ Special focus on Passerelle preparation
The Passerelle is one of the most demanding Swiss pathways because it requires strong discipline, independent thinking and solid exam technique. I help students prepare systematically in Mathematics, Physics and Chemistry by working through the required theory, typical task types, old exams and exam-style practice.

➜ BMS and Berufsmaturität support
For BMS and Berufsmaturität students, I provide structured help in Mathematics, Physics and Chemistry, depending on the programme and exam requirements. We focus on building strong foundations, closing gaps and applying methods correctly in exam situations.

➜ Matura and Fachmaturität preparation
I support students preparing for Matura and Fachmaturität exams with clear explanations, relevant exercises and a structured learning plan. The lessons help students understand difficult topics, organize their knowledge and gain confidence before important assessments.

➜ QV / final apprenticeship exam preparation
Many vocational students need Mathematics, Physics or Chemistry for their QV/final apprenticeship exams, especially in technical, scientific, laboratory, healthcare or engineering-related fields. I help students connect theory with practical calculations and exam-style tasks.

➜ Adult education and returning learners
I also work with adult learners who are returning to education after a break, preparing for Passerelle, Berufsmaturität, Fachmaturität, QV or further studies. Adult learners often need a clear, respectful and efficient teaching style. I explain from the foundation upward, without judgment, and help rebuild confidence step by step.

➜ Mathematics, Physics and Chemistry taught with equal seriousness
The focus is not only Mathematics. Physics and Chemistry are also important, especially for Passerelle, Matura, Fachmaturität, technical BMS directions, QV exams and later studies. I explain formulas, concepts and calculations clearly so students understand the logic behind the subject.

➜ Old exams and Swiss-style practice
Where suitable, I use old exams, typical Swiss exam questions and realistic practice material. Students learn how questions are asked, how to recognize the correct method, how to structure their solutions and how to avoid common mistakes.

➜ Clear step-by-step method
Every task is approached with a simple structure: What is given? What is required? Which formula, law or method is suitable? Why does it apply? Then we solve the task step by step with all formulas, calculations and explanations.

➜ Why choose a Swiss-focused tutor?
Many tutors may know Mathematics, Physics or Chemistry, but Swiss exams often have their own wording, structure and expectations. Because I studied in Switzerland and have taught Swiss students for years, I can prepare learners in a much more targeted and relevant way.

➜ For serious students who want real progress
This class is ideal for students and adult learners who want to pass an important exam, improve their grades, close knowledge gaps, prepare for further studies or gain more confidence in Mathematics, Physics and Chemistry.

➜ Success-oriented preparation
My goal is to help students build real understanding, not just short-term memorization. With clear explanations, structured practice, old exam material and consistent preparation, students can develop the confidence and exam technique needed to perform at their best.

This chemistry tutoring course is designed to help students develop a strong understanding of chemistry, improve their problem-solving skills, and build confidence in their studies. It is suitable for students studying AP Chemistry, GCSE, IGCSE, IB, A-Level, and high school chemistry, whether they need regular academic support or focused preparation for an upcoming exam.

Lessons can cover a wide range of chemistry topics, including atomic structure, the periodic table, chemical bonding, chemical equations, stoichiometry, acids and bases, energetics, rates of reaction, equilibrium, organic chemistry, electrochemistry, and other topics based on the student's curriculum and learning needs.

Each lesson is personalized to the student's level and goals. I provide clear, step-by-step explanations and guide students through practice questions and problem-solving exercises rather than simply giving them the answers. We can work together on homework, difficult topics, past-paper questions, exam techniques, and areas where the student needs additional practice.

For exam preparation, lessons can focus on understanding key concepts, applying knowledge to different types of questions, identifying common mistakes, and developing effective strategies for answering examination questions.

Whether you are struggling with a particular chemistry topic, preparing for an examination, or simply want to strengthen your understanding and achieve better results, the lessons will be adapted to your individual needs and learning pace.

Online lessons are conducted via webcam in a supportive and interactive environment, allowing students to ask questions freely and work through problems together.
