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?

Let's explore together!

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

Welcome to my profile.
I am an experienced mathematics and science teacher with over seven years of experience helping students strengthen their understanding, improve their results and become more confident, independent learners.
My lessons are designed for students and families who value high-quality, well-prepared and personalised teaching. Rather than offering a one-size-fits-all course, I adapt each lesson to the student’s level, objectives, school programme and learning style.
I teach students who need to rebuild essential foundations as well as those working on advanced topics, examinations or demanding international programmes such as the European Baccalaureate and International Baccalaureate, as well as, the various Belgian programs.

◆ MY TEACHING APPROACH ◆

• • Initial assessment • •
We begin by identifying the student’s current level, strengths, difficulties and academic objectives.

• • Personalised lesson planning • •
Each student receives a structured learning approach based on their specific needs, curriculum and pace of progress.

• • Clear and accessible explanations • •
Complex concepts are broken down into logical, manageable steps, with visual representations and carefully selected examples.

• • Active problem-solving • •
Students are encouraged to think, explain their reasoning and develop reliable methods for approaching unfamiliar questions.

• • Targeted practice • •
Exercises are selected to address specific weaknesses, consolidate knowledge and prepare effectively for tests and examinations.

• • Regular review and feedback • •
Previously studied material is revisited when necessary, and clear feedback is provided to help the student understand what has improved and what still requires attention.

◆ WHAT YOU CAN EXPECT ◆

Professionalism and reliability are central to my work:
• • Lessons prepared in advance and tailored to the student
• • Punctual and well-structured sessions
• • Patient, respectful and focused teaching
• • Clear explanations without unnecessary complication
• • Constructive and timely feedback
• • Adaptation based on the student’s progress
• • A serious learning environment that remains supportive and encouraging

My objective is not simply to help students complete exercises. I aim to help them understand the underlying concepts, develop stronger reasoning skills and gain the confidence required to work more independently.

Mathematics and science can appear difficult when important foundations are missing or when explanations are poorly adapted to the learner. With the right structure, guidance and practice, these subjects become far more logical, accessible and rewarding.

Welcome to my Foundation Course in Science and Maths, specially designed for primary, secondary, and high school students in Amsterdam. This course aims to build a strong foundation in these critical subjects, ensuring students excel academically and develop a genuine love for learning.

My teaching approach is focused on making learning enjoyable and engaging. I incorporate interactive activities and hands-on experiments to bring Science and Maths concepts to life. By involving students in these dynamic learning experiences, I aim to transform abstract concepts into tangible understanding. Each session is thoughtfully designed to keep students interested and motivated, minimizing fatigue and maximizing retention.

I believe in simplifying complex topics, breaking them down into easy-to-understand segments. This approach helps students grasp and retain challenging concepts with ease. Techniques such as mnemonic devices, visual aids, and real-life examples are integral to my method, ensuring that formulas and concepts are not just memorized, but truly understood.

Regular assessments are conducted to track student progress and identify areas needing improvement. These tests also prepare students for their school exams, ultimately boosting their confidence. I understand the importance of keeping parents informed and involved in their child’s academic journey. That's why I provide weekly reports detailing their child’s progress, strengths, and areas for improvement. This continuous feedback loop ensures that parents are aware of their child’s development and can support their learning at home.

Encouraging words and positive feedback are integral to my teaching method. I strive to build students' self-confidence and to instill a love for learning through positive reinforcement. Setting achievable goals for each student, I celebrate their successes and motivate them to strive for excellence. This goal-setting approach not only drives academic success but also fosters a sense of accomplishment and self-worth.

As a tutor, my satisfaction comes from seeing my students excel and reach their full potential. My ultimate goal is to empower students with the knowledge and skills they need to succeed in Science and Maths. I am always available to support my students, offering additional help and resources as needed to ensure their success.

I foster an open environment where students feel comfortable asking questions, no matter how simple they may seem. This curiosity drives deeper understanding and encourages a proactive approach to learning. By incorporating games, puzzles, and interesting activities, I ensure that learning remains fun and engaging, keeping students excited about the subjects.

Join my Foundation Course in Science and Maths and watch your child develop a strong foundation, confidence, and a genuine love for these essential subjects. Let’s work together to achieve academic excellence and make learning a fun and rewarding experience. “Excel in Subjects, Soar in Confidence!”
