My motto: With good explanations, anyone can understand difficult topics.
My profile: Expert in simplifying complex and abstract content.

Teacher training University of Cologne (German/Biology) and tutoring in applied linguistics.
Studied psychology (graduated with honors) at FernUniversität Hagen,conducted tutorials in statistics.
Native languages: German and English.

Several years of teaching experience in German as a foreign language, German, and biology at various age and level stages.
Successful experience in adult education (English as a foreign language) and tutoring in statistics.

Thanks to my dual professional training and experience as a teacher and psychologist, I can explain any content in a very clear, understandable, and application-based way for pupils and students. When teaching, I particularly enjoy offering you a simple and clear approach to complex and abstract topics. This allows you to have positive experiences as early as possible and enjoy learning. In addition, we can of course also address specific learning difficulties and learning techniques.

For successful teaching, I value a transparent structure in terms of content, comprehensibility, clarity, and a pinch of fun. My lessons are 100% tailored to your specific personal and school/university requirements.

A highly experienced Franco-Belgian teacher (ook in het nederlands!) offers private lessons in mathematics (including finance), probability and statistics, as well as physics, chemistry, and biology for secondary and higher education levels. For physics, chemistry, and biology, the instruction is tailored to the secondary level, specifically up to the 5th year of secondary education in Belgium.

Whether you prefer lessons at your place, my place, or remotely, I am flexible to accommodate your needs. If necessary, I can travel to your home in Brussels, Walloon and Flemish Brabant, with a minimum duration of 2 hours per session. The lessons are designed to provide extensive practice with numerous exercises. Distance learning options are also available through platforms such as Skype, Facebook, etc. Please note that for students in France, only distance learning courses are provided.

In mathematics, I specialize in various topics and frequently provide lessons covering the entire secondary school curriculum, including math 6 and higher. These topics encompass factorization, equations of the 1st and 2nd degree (with in-depth study of parabolas), limits, derivatives, integrals, exponentials and logarithms, as well as trigonometry. Additionally, I am occasionally called upon to teach analytical geometry in space, including equations of lines and planes.

For statistics and probabilities, I provide instruction in descriptive and inferential statistics (univariate and bivariate), covering confidence intervals and hypothesis tests, applicable to secondary and higher education levels.

Feel free to reach out to me to discuss and arrange the lessons based on your specific needs and availability. My aim is to help you enhance your skills effectively and provide personalized instruction. By tailoring the lessons to your requirements, we can ensure rapid progress in your studies.

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 ones needs, gives very clear explanations and most importantly works on the pronunciation of the language. With every lesson she provides lesson material.

In this course I will prepare you for the IMAT (Italian medical admission test) which happens every year and is the only way to get access to the English language medicine programme in public universities in Italy.

I will help you with the four scientific disciplines (math, physics, biology, chemistry) as well as the critical reasoning and general knowledge aspect. I will also prepare you with real-life exam scenarios in order to get used to the time limit and other constraints.

I completed Biology HL in IB with a 6 overall. I am now studying it at the university level and am ready to help students struggling with IB Biology SL. I am familiar with the syllabus and can help students break down complex topics into simpler concepts that are easy to digest.

We will begin with a lesson in order to get to know each other and see whether our goals align. We will discuss what exactly you need help with and make a weekly tutoring schedule. At the end of every class I expect students to let me know what they need help with next time or tell me 3 days before the next lesson at the latest. This ensures each class makes the most of our time together. At the beginning of the next lesson we will do a few practice questions to revise out previous class and continue with the next desired topic.

I am looking for students who are open to receiving constructive criticism. I promise I will approach all of our lessons with patience, kindness, motivation and support!
