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.

In this class, I’ll share the strategies, techniques, and exam approaches that helped me achieve those results.
This class is focused on more than simply reviewing the syllabus. We will focus on how to approach IB science questions, apply your knowledge effectively, maximize marks, and consistently perform at a 6–7 level.

What we will focus on:
- How to approach difficult IB-style questions
- Strategies for moving from a 5 to a 6 or from a 6 to a 7
- How to understand command terms and what questions are really asking
- How to structure answers to maximize marks
- Data analysis, graphs, calculations, and experimental questions
- Common mistakes that cost students marks
- Time management and exam strategy
- Challenging 6–7 level Biology HL and Chemistry HL questions

We will work through challenging IB-style Biology and Chemistry questions step by step, focusing not only on what the correct answer is, but why the markscheme awards marks for it and how to recognize similar questions in an exam.
Whether you are currently working toward a 6, trying to push from a 6 to a 7, or simply want to become significantly stronger in IB Biology HL or Chemistry HL, this class will give you a clear and practical strategy for maximizing your exam performance.

Hi! If physics is giving you a hard time and you are preparing for your GCSE or IGCSE exams under AQA, Edexcel, or OCR boards, I am here to help you take things from scratch and build complete confidence.
Here is how we go through the entire learning journey together:

Starting from the Basics: When we begin a new topic—whether it is forces, electricity, waves, or energy—we don't just jump into memorizing definitions. We start right from the very basics, breaking down what the concept actually means using simple, real-world logic.

Interactive Visual Learning: During our online session, we work on a shared digital whiteboard. I draw clean diagrams, circuit layouts, and ray optics step by step right in front of you so you can clearly visualize what is happening instead of just imagining it from a book.

Tackling Numericals: Physics formulas and calculations scare many students. We practice numerical problems slowly, learning how to rearrange formulas, substitute values correctly, and check units step by step until solving them becomes second nature.

Exam & Past Paper Practice: Once we finish a chapter, we immediately move to exam-style questions and past papers. We review how examiners mark answers, how to phraseexplanations properly, and how to manage time so you feel fully prepared and calm on your actual exam day.

Drop me a message anytime, and let's talk about which topics you want us to start working on together!
