During my lessons I always go for deep understanding. This way you will not only pass your test or exam, but you will understand the subject you are taking lessons for the rest of your life. I can also support you in how you can best learn, not just what you want to learn, and help you deal with stress. If you want to be well prepared, without stress and with confidence to pass your test, exam or exam, then you have come to the right place.

My students had a pass rate of 100% for the 2022 and 2023 exams.

About Me
My name is Marin. I have been teaching as long as I work. For myself, for companies, in class, individually, young, old, pre-vocational secondary education, gymnasium, a multitude of subjects. I have always done this with great pleasure and passion. Gradually I changed from just being a tutor who explains well to someone who coaches, motivates, helps with learning, actually supporting students and students in every aspect of their education. That's how I still teach.
I help students to understand the material on a deep level. This way they pass their test, their grades go up significantly, but they also know it for the rest of their school days, instead of just for this test. My students go from worst in class to best in class, even being asked to tutor themselves! That's what teaching is like. Really make sure that someone understands what it actually means.

I aim for deep understanding during my lessons. I ensure that you really understand and thoroughly understand the material, so that you can not only take your test, but also understand what I help you with for the rest of your school years. I am used to working with different methods and can teach at any level every year. Whether it concerns abstract economic reasoning or complex economic formulas, I will explain it to you and turn something difficult into something simple.

My students had a pass rate of 100% for the 2022 and 2023 exams.

My name is Marin. I have been teaching since I was fifteen, when I gave guitar lessons and taught 5 HAVO economics. I then worked in homework assistance, and switched to teaching at university during my psychology studies. I gave personal and classroom tutoring and lectures to between 20 and 400 students. I was manager of the branch of the national tutoring company for my faculty. I have always really enjoyed teaching, and I like the fact that I can help people further in their school careers. I have taught every age from 4 to 60 in the subjects of music, guitar lessons, economics, mathematics, business economics, statistics and English. My experience is that there are no difficult students, it is always possible to make contact and have good tutoring!

I am a qualified and experienced mathematics tutor. Graduated from the Free University of Brussels in 2011, I started my career by teaching remedial courses in different schools in Brussels. I then specialized in individual academic support by following educational training at the Harvard Graduate School of Education. I have been giving private mathematics lessons daily for over ten years.

The students who follow my private lessons benefit from personalized support. The first session is devoted to an in-depth assessment of the student's mathematical knowledge. The objective is to detect its weak points and understand their origin in order to adapt my courses to its needs. I develop a tailor-made remediation program for each of my students aimed at filling each of their gaps. Over the course of the sessions, the student builds a solid foundation for learning and regains self-confidence. At the same time, I help him acquire a work methodology that allows him to gradually become autonomous in his studies.

I have a thorough knowledge of the mathematics curriculum for middle and high school (from 6th to 12th grade). I am also qualified to support students in preparing for international exams such as the SAT, the OMPT, and the International Baccalaureate (IB) in all its variations: Analysis and Approaches (AA SL/HL) and Applications and Interpretation (AI SL/HL).

Throughout my years of training, I studied and developed numerous techniques that facilitate learning mathematics. The strength of my teaching approach lies in my ability to explain, in simple terms, anything a student finds complicated. I am passionate about this profession because it offers me the opportunity to guide struggling students toward success. It is a true pleasure to see them progress and rediscover their connection with the fascinating world of mathematics.

I offer private tutoring in Paris (at the student's home) or remotely (online). My online lessons take place on an interactive whiteboard. This whiteboard is specifically designed to facilitate student/teacher interaction online. Thanks to this teaching tool, my online lessons are just as effective as in-person lessons. The student only needs an internet connection and a computer, tablet, or smartphone to participate.

By delving deep into the practical applications of statistics and data science, this course is designed to set you up for success.

Learn from real-world examples: Instead of spending hours on theoretical material and trying to relate it to practical issues, we will focus solely on applied statistics. Programming will allow you to apply theory to real-world problems, equipping you with the knowledge and skills you need to succeed.

We won’t be spending hours solving math problems by hand for reinforcement, as this isn’t school. Instead, we’ll use cutting-edge methods and code libraries that leverage the latest software releases to maximize productivity and efficiency.
