I am Christian, graduated in chemistry at Utrecht University (Biomolecular Sciences) and have a PhD in developmental biology. For several years now I have been tutoring and exam training in mathematics, chemistry and physics to HAVO and VWO students, but also to HBO students and Cambridge International A-levels. Maybe I can help you too!

The lessons are given online, but I provide a personal and interactive approach. With a marker and whiteboard I create an atmosphere that is comparable to private lessons at your home.

Every student has unique goals and a unique way of learning. That is why I tailor my lessons to your needs. I am always involved in your progress and am optimistic and approachable by nature. During the lessons I often notice that students not only understand the material better, but also their self-confidence grows.

Besides being a tutor, I am a part-time artist (painter and musician). My creative background gives me a fresh and enthusiastic perspective on science subjects. If science subjects feel hard, difficult or boring, or if you had a teacher who couldn't make it fun, I can help you change that. The more you understand, the more fun it becomes, and good grades will follow!

I'd love to meet you!

Sciences are some of the most challenging subjects in primary and middle school, and some of the most exciting nonetheless; I will help your child see the beauty and simplicity in the heart of physics, chemistry or biology, and thus excel at them.

My approach is flexible. I can do any of: re-explain difficult material to the student; help with homework; supervise and guide them in preparation for exams and tests. All my teaching, however, is always accompanied by quizzes and questions to ensure understanding and gauge progress.

I'm a high-school student specialising in these subjects, consistently scoring best-in-school scores for them for the past 5 years. Although my main area of interest in mathematics - I am a member of the Cyprus National Mathematics Team - my mathematical and educational passion swiftly translates into science tutoring talent. I already possess experience in teaching sciences, teaching a student in 9th grade biology.

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).

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.
