I have been successfully teaching Swiss students for many years and have gained extensive experience with cantonal education in various regions of Switzerland. As an experienced, local tutor, I am intimately familiar with the requirements, structures, and curricula of the Swiss school system. I have all past exam papers at my disposal and have prepared numerous students for their cantonal and national exams in a targeted, sustained, and highly successful manner. I place particular emphasis on closing knowledge gaps, building self-confidence, and offering each student individualized support that supports them in the best possible way. My goal is not only to improve grades, but also to develop a long-term joy in learning and lay the foundation for academic success.

►Targeted exam preparation for:

High school entrance exams
BMS & Passerelle exams
International Baccalaureate (IB)
ETH courses & university modules
ZHAW & University of Applied Sciences

► How do I teach?
►I always emphasize a complete understanding of problems, not just learning methods: This ensures you get the maximum benefit from tutoring. I take the time to clarify concepts and address individual questions until everything is truly understood.

►The reason for my success lies in my ability to adapt my learning style to meet the needs of my students. I carefully observe which methods work for each student and adapt my teaching flexibly.

►I offer practical and lively examples to explain concepts in mathematics, physics, and chemistry. This makes theoretical knowledge tangible and ensures long-term retention.

►I am very patient and strive to eliminate the difficulty in key concepts by simplifying seemingly complex procedures. No student is left behind—my goal is a solid foundation.

►I firmly believe in building a positive working relationship with my students. Trust and a relaxed atmosphere are the foundation for sustainable learning success.

►Intensive exam preparation (e.g., during the holidays), subject-specific topic work, or overcoming test anxiety for all ages. Together, we develop a concrete plan and train under realistic conditions.

►I'm also a highly experienced online tutor and can deliver a lesson as effectively as possible in person using an interactive whiteboard. All materials and documents are shared in real time, making the lesson just as productive as in-person.

►Locations: At your home, online, or by appointment. I am flexible and adapt to your wishes and needs to achieve optimal learning results.

SOME REVIEWS:
Chevaan:
Catherina is without a doubt THE best tutor we know. She is exceptionally committed and is always looking to inspire her students. She has consistently gone above and beyond the call of duty to help our son with his German. She provides excellent study material, engaging homework and follows up to ensure that her students have really grasped the subject matter.

Brian:
Catharina has been teaching our 11-year-old daughter for the past few months, and we are very impressed with her excellent progress in this short space of time.
Catharina has developed a very good rapport with our daughter and is patient and knowledgeable. Our daughter always looks forward to her next lesson and even hands in her homework on time! We would highly recommend Catharina to anyone who would like to learn a new language.

Afeisha:
Very professional, friendly and informative. I feel like Catharina will help me to reach where I need to. She doesn't just teach from the book, she teaches in a way that will allow you to blend in with ease. I am excited to learn more from her.

Egle:
Great tutor! Catharina adapts lessons to one's needs, gives very clear explanations and most importantly works on the pronunciation of the language. With every lesson she provides lesson material.

The objective is that: the learner masters the English language (🎧listening-comprehension,🎤 conversation, 📚 reading, grammar-pronunciation, writing...). It helps him to have language skills like native speakers. 🥇

At the same time, the learner will be 🚴‍♀️dynamic and well supervised by professional tutors who listen.
The atmosphere is distinguished: 🔥learning, interaction, no routine, no stress.

The learning tools used; videos, audios, texts, articles, images, games, stories...

We are happy to help both adults and pupils/students. If you want to learn the English language (reading, grammar, oral conversation, written production,...) or you have homework to do, or competitions/tests to take, 🏆 contact us :)

Each lesson is fully personalized to your level, goals, and specific needs (exams, immigration, work, studies, administrative procedures).

Sessions can focus on:
- DELF, DALF, and TCF exam preparation (practice tests, methodology, assessment criteria, oral and written simulations)
- French for immigration and naturalization
- Administrative French (forms, letters, understanding official documents)
-Professional and business French (emails, meetings, interviews, industry-specific vocabulary)
-Improving speaking skills, pronunciation, and fluency
-Strengthening grammar and vocabulary in context

The lessons are dynamic, structured, and interactive, with a strong emphasis on speaking practice. I use authentic materials: exam topics, administrative documents, articles, videos, and professional dialogues.

Thanks to my experience as an oral exam jury member and as a DELF, DALF, and TCF examiner, I will help you understand exactly what examiners expect and adopt the right strategies to succeed.

Regular follow-up is provided, with clear objectives and detailed feedback to track your progress and build confidence.

Welcome!
Are you ready to start speaking and writing English with confidence? My lessons are fun, interactive, and personalized to your level. We focus on practical English you can use in everyday life — talking to friends, traveling, or preparing for school or work.

In each lesson, you’ll practice:

-Speaking in full sentences
-Writing short texts and messages
-Understanding grammar in context
-Boosting your confidence in English

I create my own materials tailored to your level and goals, and I can also supplement lessons with online worksheets or teach from a textbook if you prefer — you’ll participate in the lesson directly from the book without me providing copies.

The first lesson will allow you to experience my teaching style and get comfortable with the format before moving on to longer lessons. Lessons are tailored to kids, teens, or adults, so each session is adapted to your goals and learning style. I teach lessons in English or German, depending on what’s most comfortable for you.

Book your first lesson today and take the first step toward speaking English confidently!

I am a student at the Polytechnic University of Valencia. I have a degree in Aerospace Engineering and am currently pursuing a Master's degree in Aeronautical Engineering. I scored 13.8/14 on the university entrance exams. I am familiar with the exam format and can help students prepare for them. I can also reinforce knowledge from other levels, making high school much easier. I have over five years of experience tutoring students to prepare for the university entrance exams and first-year university subjects. I also help reinforce fundamental concepts in lower grades to ensure students are as prepared as possible for the university entrance exams.
