I offer you a new learning experience.

The focus is on practical application and theory is only introduced where intuition reaches its limits.

Whether you are a beginner or an advanced learner, my tailor-made lessons will accelerate your language acquisition in a positive learning environment.

You can book a complete course with regular sessions or individual lessons to overcome a specific problem, such as pronunciation or a particular point in grammar.

Learning a foreign language is not a linear process that consists of memorising a list of words, and speaking a foreign language is not an oral translation exercise.

There are two types of approaches to acquiring knowledge:

When asked what year follows 1999, you can immediately answer 2000 without having to think for a long time and, above all, without having memorised each number individually, starting with 1, 2, 3 ... You know that numbers are formed according to a certain pattern. With only ten digits, you can form an infinite number of numbers and always know which number comes next.

When it comes to the alphabet, words and sentences, it's more or less the same, but school pedagogy, school textbooks and regular lessons still follow the rote learning approach. In the lessons I propose, you will learn to use patterns because this is more efficient and faster.

Learning is easy, but unlearning bad habits is extremely difficult. This makes it all the more important to learn the right reflexes as early as possible.

My offer is aimed at both young people and adults who want to learn German or improve their knowledge without wasting time on nonsensical school methods.

I offer individual or group lessons for German. The methods are based on cognitive science and, in particular, comparative linguistics. My flexible programme can be tailored to your individual needs. The programme focuses on your independence in spontaneous conversations in real life.

What is particularly important to me:

motivating my students and help them establish a learning rhythm;
encouraging their creativity;
helping them become more familiar with the language;
teaching them the letters and their sounds;
strengthening their memory by training their phonological loop;
teaching sentence building plans instead of memorising sentences;
explaining how language works so that my students can become independent as quickly as possible.

I look forward to meeting you.

*All classes are one-on-one and tailored to the individual student's needs and requirements. The ultimate goal is that the student thinks in the language not just translates.
*All key aspects of the language will be addressed including cultural aspects/linguistic differences.
* Whether a quick learner or not; it will be fun and comprehensible. There is a goal to achieve and it will be done.
* Whether learning a language to improve your career, for travel or even romantic reasons, help is at hand - just reach out.

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

I help both for private purposes, business and for school. My lessons are mainly result-oriented. It is my intention to achieve a maximum result in a pleasant way. I have already helped many children, young people and adults.
I adapt to the level and the intended result
I keep my lessons varied but still challenging.
I also really enjoy teaching students. I can teach them the basic knowledge they lack, while also working on the new knowledge they need to acquire.
I do my work with passion and 100% motivation.
It makes me happy to see that my students are also enjoying their progress, that's why I have a very good relationship with my students.

I'd like to start by greeting everyone who is reading this and then briefly discuss the teachings I'm providing. Going to medical school is a major step, and while becoming a doctor may have been a big dream of yours, things unfortunately didn't turn out the way you had hoped. You didn't receive what you eagerly want following your bac. I'm here to tell you that earning your bac is just the first step on a longer journey. You have another opportunity to fulfill your lifelong ambitions. What role do I play in this? as someone who has been in your position and ultimately obtained what I want. We will have a customized plan that fulfills your needs, we will correct any unsuccessful methods and build new ones, and I will lead you through the program at every stage.

Welcome to university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.
