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.

Hello,
Currently an engineering student at École Centrale after two years of scientific preparatory classes, I offer tailored support in Mathematics/Physics for students from secondary level I (from 8th/9th grade) up to the preparation of the Maturity (Gymnasium / College).

Having acquired a solid working method, I support my students to help them overcome their blocks, understand their courses in depth and gain autonomy, whether for a refresher course or to aim for academic excellence in the science section.

My working method:
- Clear and reformulated explanation of the sticking points of the Romand program.
- Immediate application via targeted exercises.
- Acquisition of problem-solving and organizational methods.

Course organization (100% online and interactive):
I am fully equipped to guarantee remote tutoring of the same quality as in-person tutoring. Thanks to the use of a graphics tablet, a stylus, and a shared interactive whiteboard, the student sees what I write in real time, and we solve mathematical and/or physics problems together, step by step.
This format is ideal for very smooth weekly tracking, with great flexibility in scheduling to fit your child's timetable (evenings, weekends and sometimes even during the day).

Feel free to contact me to discuss your child's needs!

Hi, I'm Darioush! I'm a Computer Science student at Tbilisi State University (English-track program), based right here in Tbilisi.

Science has been my world since high school — I won a bronze medal at the Iranian National Astronomy Olympiad, competing against thousands of students nationwide. That competitive background gave me something most tutors don't have: I don't just know the textbook answer, I know why it's the answer, and how to break it down so it actually clicks.

I teach Physics and Mathematics from middle school through high school level, including exam prep and olympiad-style problem solving. I love bringing in real astronomy examples to make abstract concepts feel tangible — physics is just astronomy that hasn't looked up yet.

My teaching style: build intuition first, then speed. No memorizing formulas without understanding where they come from. Whether you're catching up, aiming for top grades, or prepping for a competition, I'll adapt to your pace and goals.

Fluent in English, lessons available in person in Tbilisi or online.

Let's make science make sense. 🚀
