I am a theoretical physicist working at Stockholm University. I obtained my PhD in Applied Mathematics from Queen Mary University of London and I have taught at both Queen Mary University of London and King's College London. I am experienced in teaching modules including Calculus, Linear Algebra, Vectors and Matrices, Machine learning, and introductory physics courses and I have been nominated as an Outstanding Teaching Assistant at King's College London.

My current research area is dynamical systems and statistical physics. Other physics and mathematics modules can be discussed upon request.

Discuss your request with me before booking classes so that I can better design the class accordingly.

I am a mathematician with a PhD, and I can offer classes on any topic from the high school curriculum, and main topics from the undergradute level, such as Calculus, Analysis, Linear Algebra, Abstract Algebra, Geometry or Topology. I focus on the story and philosophy behind the topics, which I believe facilitates the development of techical skills for solving relevant questions.

When I was a young child, I believed I was not a mathematical person.

It wasn't until I met an amazing teacher at age 15 that I discovered my mathematical genius and my life was changed forever.

I'm eternally grateful to that teacher.

My teacher knew that self-image and self-belief is the key to unlocking your child's mathematical abilities.

Everyone is good at maths, but we all have different styles of thinking.

Bad teachers teach every child the same way.

My job is to find your child's style of mathematics and allow him to discover that for himself.

When he discovers that, he will begin to enjoy the beauty and power of mathematics...and then you will see as the grades begin to soar.

The courses of Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Mechanics - Electricity - Chemistry - Organic Chemistry - Biology, Geology of the French or European French or English programs (Secondary or university levels) are given by explanations either in depth or by a rapid course and summary of essential need according to the case of each student supported by exercises from the book or by evaluations and exams from other high schools.
My experience is too long and for years, I have learned methods for each case and for each student to fill their gaps with the best results of Excellent, Very Good, and Good as mentioned by my students.
I can also help students to better prepare for courses and support them to better prepare for the duties of CNED in science subjects.

* I teach math exclusively ONLINE using a pen tablet and interactive whiteboard, so you can see both me and my step-by-step solutions in real time.

My name is Eli, and I’m here to help you understand math in the simplest possible way. Whether you need support with homework, want to prepare for exams, or aim to strengthen your skills, I’m ready to guide you.

I have over 10 years of teaching experience in Math, IB Math, SAT Math, Calculus, Algebra, Matrices, and Geometry. Before each lesson, I prepare tailored materials, including theory, examples, and exercises; so we can work through them together. In my classes, you can ask as many questions as you like, and we won’t end the session until everything is clear.

I hold a Doctoral degree in Electrical Engineering from Aalto University and work in an R&D role where I apply mathematics daily. I know how valuable a solid math foundation is, both in school and in real life.

Let’s make math clear, simple, and even enjoyable. I look forward to meeting you!

I usually teach math and statistics in English for students who want to become scientists.I help write a good paper. As long as Corona is there, it is also possible via Teams, Zoom or Skype, but in principle the lessons in my building are within walking distance of the Central Station or somewhere in sollentuna, kista and tensta.
You will enjoy while learning math.
A combined course in algebra: Systems of equations: inequalities, graphs and functions; radicals, quadratic polynomials, rational expressions; exponential and logarithmic functions, and problem solving, with emphasis on knowledge skills appropriate for students pursuing.

I am a student in the 3rd year of the engineering cycle at SUAPERO (top 10 engineering school), in a gap year at KTH in a master's degree in advanced physics. Previously I was preparatory to the Lycée St Louis in class of MPSI then MP* (Physical Maths) which allowed me to obtain very good results in the BAC+2 competitions.

For more than 3 years I have been giving private lessons in Maths and Physics for high school students and preparatory students (11 students). It's always the same philosophy that drives me: to appreciate what the student learns so that he learns it well and knows how to reuse it to perfection to perform during exams and competitions! But despite this constant, the lessons revolve around the personality of the student, what he dreads, where he is comfortable, but especially where he is not comfortable because it is where there is the greatest room for improvement and therefore the most points to get.

Concretely for the organization of the lessons, I plan in advance with the student what he wants to work on at the next session, then schedule a meeting by videoconference or on site according to the times that suit him best. The system is thus very flexible to meet the needs of the student, wherever and whenever. With the 6 students with whom I set up this system, the operation was very fluid. Equipped with a tablet that acts as a table when remotely, we come back over the course of the session to the points of the course and the exercises that the student wishes to work on and the important method points. The key points of the sessions are highlighted on a sheet which is given to the student at the end of the session to provide him with a revision support.

See you soon !

Learning languages can be a very challenging task to do. Mainly when the classes are boring, go too fast and teach you things you feel like will never be able to use in real life.
In my class I will teach you vocabulary, grammar, conjugation, as well as pronunciation, talking and hearing skills. I will differ my teaching on what you want to focus on, if it is for school work or personal goals. As I am a native speaker, I can also teach you about french culture, society and mannerisms (whatever you are curious about!). My wish is for you to feel that you are learning at a comfortable pace while having fun, and feeling that what you are learning is relevant to your goal. I think it is also important to have a variety of ways you can learn. We can watch french movies, read certain books you could be interested in, or even play some games, so you would learn in different ways :)
We can meet for a first session, to familiarize each other, and for me to learn more about you and your goals, so I can prepare the best for our next coming lessons :)

I am Mavi, a physics engineer working at an aerospace company.
I have been teaching private lessons at the primary, secondary, high school, and university preparatory levels for 11 years. I teach mathematics, physics, chemistry, and science. I have a good command of the curricula of IB, IGCSE, American, Hong Kong, and international schools.

Additionally, I hold the position of president at the Astronomy Society, where I foster my students' interest in astronomy and science beyond the lessons. I prepare the learning environment by incorporating experiments and exploration, moving away from rote education. I often bring experimental materials to class, aiming to make learning memorable through hands-on experiments.

As an educational mentor, I approach my students as if they were my siblings, valuing creativity. I have a deep passion for mathematics, physics, and science. I am dedicated to helping students understand and learn because life encompasses both SCIENCE and ART. The more people I can inspire to know, understand, and love mathematics, physics, and chemistry, the more proud I am.

Are you curious about how nature works?
