Hi! Welcome! I am a Ph.D. researcher in Physics at the University of Cologne, Germany. Recently, I graduated from the University of Groningen in the Netherlands with a Master's degree in Nanoscience (w/ cum Laude). I offer private tutoring (for high school and/or university-level students) so you can understand the fundamental concepts and excel in your studies. I have teaching experience of 5+ years in Physics and Mathematics to both high school and university-level students.

This class aims to provide an overview of calculus and linear algebra and focuses on the fundamental mathematical tools and concepts, such as limits, differentiation, and integration. Building on these basic concepts, we will review methods for solving problems related to optimization, linear differential equations, and matrix algebra.

Outline of the course:
1. Calculus:
1.1 Limits of functions
1.2 Continuity, types of discontinuities, intermediate value theorem
1.3 Differentiation (or derivative), slope, secant, tangent
1.4 Rules and theorems for differentiation, power rule, product rule, chain rule
1.5 Derivatives of exp, log, and trigonometric functions
1.6 Implicit differentiation and derivative of inverse functions
1.7 Rolle's theorem, mean value theorem, critical point, maximum/minimum of a function
1.8 First and second derivative tests, inflection points
1.9 Anti-derivative, indefinite integral, integration by substitution, integration by parts
1.10 Definite integral and its application (area between curves, application in physics)\
1.11 Optimization and linear differential equations

2. Linear Algebra:
2.1 Vectors and scalars in Euclidean space, vector arithmetic, scalar product, cross product
2.2 Equations for lines and planes, vector spaces, linear independence, span, basis, dimension
2.3 Linear transformations, coordinates, and representation of linear transformations by matrices

Bachelor's student in economics and management offers private lessons in mathematics.
I obtained my bachelor's degree with a specialization in mathematics and physics and I have sufficient knowledge in mathematics, physics, chemistry, German, English and French.
In my teaching, I adapt to the learning conditions and the student's life in order to strengthen their self-confidence and ensure that they understand the lessons and progress.

My goal is to create an effective learning environment. I rely on the student's course, which I supplement if necessary with additional information.

Is your child in their final year of high school and understands the lessons, but struggles to solve the exercises on their own?

He knows the formulas, but doesn't know how to use them in an exercise?
Does he get stuck on problems or multi-step exercises?
His grades remain low despite his efforts?
Is he lacking in method, speed, or confidence?
Or perhaps the Baccalaureate exam is approaching and he doesn't know how to organize his revision effectively?

I can help him transform these difficulties into methods and skills.

I am a mathematics teacher with 15 years of teaching experience and hold a Master's degree in mathematics. I primarily support high school students, especially in their penultimate and final years, following both the Moroccan and French curricula.

🎯 My goal: to understand why the student is stuck

In mathematics, a bad grade does not always mean that the lesson is not understood.

The student may have:

• gaps stemming from previous years;
• difficulties in understanding certain concepts;
• methodological problems;
• difficulties in analyzing a statement;
• difficulty choosing the right problem-solving strategy;
• errors in calculation or reasoning;
• difficulties in writing a solution correctly;
• a lack of training or confidence.

My role is to identify these difficulties and to work progressively on the points that are really preventing the student from progressing.

📚 Preparation and support in the final year of high school

Specifically, we can work on:

• the functions;
• limits and continuity;
• Derivation and variations;
• exponential and logarithmic functions;
• the sequels;
• antiderivatives and integrals;
• probabilities and random variables;
• geometry;
• differential equations according to the program;
• synthesis exercises and problems;
• Methodology and writing.

The content is of course adapted to the program followed by the student.

📝 Baccalaureate Preparation

For a student preparing for the Baccalaureate, we can implement a structured approach based on:

Understand → Practice → Correct mistakes → Try again → Gain independence

We work with progressive exercises, exam topics and problems adapted to the student's actual level.

The goal is not to mechanically memorize methods, but to be able to recognize a situation, choose a strategy and correctly construct a solution.

For my final year students who were tutored in mathematics, I achieved a 100% success rate in the Baccalaureate, with 75% obtaining a distinction of "Bien" or "Très Bien".

💻 Interactive online courses

The sessions take place remotely using Google Meet and an interactive whiteboard.

The student actively participates during the session: he searches, reasons, writes and corrects his mistakes with my guidance.

After the session, I can also provide screenshots of the work done so that the student can review the important points.

👨‍🎓 This support is particularly suited to students who:

• want to improve their results;
• have accumulated deficiencies;
• understand the lesson but get stuck on the exercises;
• need a more efficient working method;
• are preparing for a test or exam;
• wish to prepare seriously for the Baccalaureate;
• want to gain autonomy and confidence.

Each student has different difficulties. Therefore, I begin by identifying their needs before designing the work to be done.

📩 Are you preparing for a test or the Baccalaureate?

In your message, simply tell me:

• the student's level;
• the program followed;
• the chapters that pose a problem;
• the desired objective.

This will allow me to quickly understand the situation and propose a suitable approach.

My goal: to help the student understand mathematics, master problem-solving methods, and approach exams with greater confidence.

I work with two kinds of students: those preparing to meet university math admission requirements (OMPT, CCVX, VWO), and those already enrolled who need solid support in calculus, linear algebra, differential equations, probability & statistics, or discrete math including students at TUM, ETH Zurich, TU Delft, KTH, EPFL, and RWTH Aachen.
Lessons are in English; I can explain in German where it helps.

Math, calculus and physics can sometimes be overwhelming, especially when the theory or solving method is unclear. I am a cum laude Aerospace Engineering graduate from TU Delft and have helped other pupils with their problems since 2017. With my calm and stepwise explanation, a second alternative view of the solution procedure is given, which is often what is missing. I tutor a variety of math and physics courses on both secondary and high school levels, but also at a scientific bachelor level. These can either be theory/exercise-based, but also exam preparation.

My name is Badr and I am passionate about teaching mathematics. I offer private mathematics lessons in English🇬🇧 and French🇫🇷 tailored to students from primary to high school, including preparation for the baccalaureate and 3rd year middle school exams.

Using a clear and progressive approach, I simplify complex concepts to enable each student to better understand, gain confidence, and make lasting progress. Whether in arithmetic, algebra, geometry, or analysis, my sessions are personalized according to the level, pace, and needs of each student.
My goal: to help each student build a solid foundation, overcome their obstacles, succeed in their exams, and excel in their academic career.

I hold a PhD in Mechanical Engineering and currently work as a post-doctoral researcher in the Aerospace Engineering Faculty at TU Delft (Delft University of Technology).
Key topics that I teach for this course include:
• Calculus: Differentiation & integration, Multivariable calculus
• Linear Algebra: Matrices, vectors, systems of equations, Eigenvalues and eigenvectors
• Differential Equations: First- and second-order ODEs, Laplace transforms
• Complex Numbers: Polar form, Euler’s formula
• Vector Calculus: Gradient, divergence, curl, Line and surface integrals
• Series & Transforms: Taylor series, Fourier series

I understand that not all teachers excel in teaching Engineering and Mathematics courses and explaining their importance to students. Courses with strong mathematical backgrounds may become boring for students who lack a solid mathematical basis. To address this, I take a student-centered approach, starting from the basics to actively engage all students, including those with weaker mathematical backgrounds. I also provide practical examples to demonstrate the real-world significance of what they are learning, inspiring and fostering their interest in the subject matter.

If you have any additional questions before starting a class, please feel free to ask me. I am here to assist! :)

I have graduated with a degree in chemical engineering from the University of Edinburgh, UK. I am also an Erasmus Mundus scholar with a master's in Analytical Chemistry from Uppsala University. Currently, I am pursuing a PhD in physical chemistry.

I have been tutoring since 2012 to fund my education expenses. I formally began tutoring in 2014 as part of my vocational training as a teacher in Ghana, funded by the University of Edinburgh. The formal training has taught me a lot about curriculum development, time management, and fusing my teaching methodology to my students’ needs. I have been tutoring in Physics, Chemistry, and Math, in person and online; the hybrid model has allowed me to reach out and teach students in 8 different countries. I have successful students from these past nine years who have not only commended my work ethic but can also stand testament to my enthusiasm.

My excellent academic career has nurtured in me a natural talent for teaching. My experiences have taught me how to tackle one problem at a time, and I believe that using this approach—paired with my unconventional examples that force students to think outside the box—I can truly provide an excellent understanding and explanation. My teaching methodology is based on two main things: skill development and adaptation. Initially, I create a skeleton of the most suitable methodology tailored to the preferred curriculum, after which, I adapt that lecture to the specific needs of the student based on their knowledge and grasp of the concepts. Second, I like to develop analytical and scientific ability along with knowledge in my students, and for that, I use a combination of resources in the form of worksheets, class tasks, and past papers. Last, I believe in the strong ethic of providing feedback to the parents, so that they are aware of their child’s progress.

Frequently Asked Questions:
Which subject(s) do you teach?
I teach math, mechanics, statistics, chemistry and physics. I also teach biology up to GCSE level.

When are you available? My timetable is quite flexible. I am happy to work weekdays, week evening and weekends.

Which ages and levels do you teach? The majority of my students are between the ages of 10-18, but I also teach college Students. I am also helping foundation and first year university students.

Which qualifications do you prepare your students for? GCSE, IGCSE, A/S-level, A-level, IB, School entrance exams and SATs

Describe your arrangements for online tutoring? I use Zoom online sessions since it has many tools and features specially designed for interactive and visual learning. I am fully equipped with modern gadgets for e-learning. I use Google drive and docs to share files.

Having coached 100+ students from more than 10 universities worldwide, I have developed a strong understanding of the homework expectations, assessment methods, and exam styles commonly used in university-level mathematics courses.

One of the biggest challenges students face in university calculus is the transition from high school mathematics. Differences in curriculum, notation, problem-solving approaches, and calculator usage can create significant knowledge gaps that make it difficult to keep up with the course material.

I help students identify and close these gaps by strengthening the underlying mathematical foundations and developing the skills required for success in higher education. Whether you are struggling with prerequisites, falling behind in lectures, or aiming for top grades, lessons are tailored to your specific needs and course requirements.

I provide comprehensive support in Calculus I, II, and III, including:

- Limits and continuity
- Differentiation and applications of derivatives
- Integration techniques and applications
- Sequences and series
- Multivariable calculus
- Partial derivatives and multiple integrals
- Vector calculus and related topics

I can help you understand assignments and prepare for exams, build the confidence and understanding needed to excel throughout your university studies.
