Welcome to my profile.
I am an experienced mathematics and science teacher with over seven years of experience helping students strengthen their understanding, improve their results and become more confident, independent learners.
My lessons are designed for students and families who value high-quality, well-prepared and personalised teaching. Rather than offering a one-size-fits-all course, I adapt each lesson to the student’s level, objectives, school programme and learning style.
I teach students who need to rebuild essential foundations as well as those working on advanced topics, examinations or demanding international programmes such as the European Baccalaureate and International Baccalaureate, as well as, the various Belgian programs.

◆ MY TEACHING APPROACH ◆

• • Initial assessment • •
We begin by identifying the student’s current level, strengths, difficulties and academic objectives.

• • Personalised lesson planning • •
Each student receives a structured learning approach based on their specific needs, curriculum and pace of progress.

• • Clear and accessible explanations • •
Complex concepts are broken down into logical, manageable steps, with visual representations and carefully selected examples.

• • Active problem-solving • •
Students are encouraged to think, explain their reasoning and develop reliable methods for approaching unfamiliar questions.

• • Targeted practice • •
Exercises are selected to address specific weaknesses, consolidate knowledge and prepare effectively for tests and examinations.

• • Regular review and feedback • •
Previously studied material is revisited when necessary, and clear feedback is provided to help the student understand what has improved and what still requires attention.

◆ WHAT YOU CAN EXPECT ◆

Professionalism and reliability are central to my work:
• • Lessons prepared in advance and tailored to the student
• • Punctual and well-structured sessions
• • Patient, respectful and focused teaching
• • Clear explanations without unnecessary complication
• • Constructive and timely feedback
• • Adaptation based on the student’s progress
• • A serious learning environment that remains supportive and encouraging

My objective is not simply to help students complete exercises. I aim to help them understand the underlying concepts, develop stronger reasoning skills and gain the confidence required to work more independently.

Mathematics and science can appear difficult when important foundations are missing or when explanations are poorly adapted to the learner. With the right structure, guidance and practice, these subjects become far more logical, accessible and rewarding.

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.

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.
