Need help with math or science? As a 33-year-old civil engineer, I'm happy to help! I'll learn at your own pace, using plenty of examples to illustrate the material. I have years of experience teaching both simple and complex subjects.

The lessons run as follows. First of all, together we look for the student's biggest stumbling blocks. These can be related to the subject matter as well as to the study method. From there, I continue to work at the pace of the student and encourage them to ask as many questions as possible. I also give them tips and tricks, and improve their working methods where necessary. During the lesson I give many examples to make the subject matter more interesting and we solve exercises together. Once the student has mastered the exercises from the lesson, I give some more challenging exercises to also test on the deeper understanding of the subject matter. In this way I try to optimally prepare the student for his / her test or exam.

However, learning should also be enjoyable. That is why I always strive for a good relationship with the student through a spontaneous and positive approach. I am also very patient. All this lowers the barrier to ask questions and improves the student's learning process.

Are you interested? Do not hesitate to contact me!
See you soon!

As a dedicated tutor with extensive experience in preparing students for standardized exams such as the SAT, GMAT, and SSAT, I understand the unique challenges that each of these tests presents. My approach is comprehensive and focuses on building a strong foundation in critical areas such as Mathematics, Quantitative Reasoning, Verbal Skills, and Analytical Writing. Each program I develop is tailored to the specific requirements of the exam, ensuring that students are well-prepared and confident on test day.

Having a deep understanding of the test formats and question types allows me to provide personalized strategies that target each student's individual strengths and weaknesses. I believe that every student has a unique learning style, and my goal is to enhance their test-taking skills while improving their time management. By fostering a supportive learning environment, I aim to boost students' confidence and empower them to achieve top scores.

My tutoring sessions incorporate a variety of effective methods, including real exam questions and timed practice tests. This hands-on approach allows students to familiarize themselves with the types of questions they will encounter, making the actual exam feel less daunting. I teach proven techniques for tackling even the most challenging problems, ensuring that students feel equipped to handle any question that comes their way.

One of the key components of my tutoring is helping students develop effective study habits. I provide guidance on creating a structured study plan that maximizes their preparation time and aligns with their personal goals. This structured approach not only keeps students on track but also helps them build a sense of accountability, which is crucial for success.

In addition to academic preparation, I also focus on the psychological aspects of test-taking. Many students experience anxiety leading up to exams, which can affect their performance. I teach relaxation techniques and mental strategies to help manage stress, allowing students to approach their exams with a calm and focused mindset. By addressing both the academic and emotional challenges of test preparation, I equip students with a well-rounded toolkit for success.

Feedback is an essential part of the learning process, and I make it a priority to provide constructive and actionable insights during our sessions. After each practice test, I conduct a thorough review of the results, highlighting areas for improvement while also acknowledging progress. This continuous feedback loop helps students understand their growth and keeps them motivated throughout their preparation.

My commitment to student success goes beyond just teaching content. I aim to inspire a love for learning and self-improvement in each of my students. Many of my former students have gone on to achieve their academic goals, securing places at prestigious universities and programs. Their success stories are a testament to the effectiveness of my tailored approach and the dedication I bring to each tutoring session.

Ich studiere Computer Engineering an der RWTH Aachen und biete individuelle Nachhilfe in Mathematik, Physik und naturwissenschaftlichen Grundlagen an – von den ersten Grundlagen bis zur Oberstufe und zum Abitur.
Besonders wichtig ist mir, dass Schülerinnen und Schüler den Stoff wirklich verstehen, anstatt Formeln und Lösungswege nur auswendig zu lernen. Ich erkläre Zusammenhänge Schritt für Schritt, passe Tempo und Schwierigkeitsgrad individuell an und arbeite gezielt an den Stellen, an denen noch Unsicherheiten bestehen.
Wir können gemeinsam:
- aktuelle Themen aus dem Unterricht aufarbeiten,
- Hausaufgaben und Übungsaufgaben besprechen,
- Wissenslücken systematisch schließen,
- uns auf Klassenarbeiten, Klausuren oder das Abitur vorbereiten,
- und schwierige Themen mit zusätzlichen Aufgaben festigen.
In Mathematik kann ich unter anderem bei Algebra, Gleichungen, Funktionen, Geometrie, Trigonometrie, Analysis, Vektorrechnung und Wahrscheinlichkeitsrechnung helfen.
In Physik unterstütze ich unter anderem bei Mechanik, Elektrizitätslehre, Energie, Schwingungen/Wellen und weiteren schulischen Themen.
Durch mein Ingenieurstudium beschäftige ich mich selbst intensiv mit höherer Mathematik, Physik und technischen Anwendungen. Daher kann ich bei Bedarf auch fortgeschrittenere Schülerinnen und Schüler sowie Studienanfänger in mathematischen Grundlagen unterstützen.
Der Unterricht kann auf Deutsch oder Englisch stattfinden und wird individuell an das Niveau und die Ziele des Schülers bzw. der Schülerin angepasst.
Mein Ziel ist, dass Mathematik und Physik nicht mehr wie eine Sammlung zufälliger Formeln wirken, sondern Schritt für Schritt logisch und nachvollziehbar werden.
