In my class, I would like to help my students with the necessary tutoring and proper direction towards understanding natural science subjects such as Physics, Chemistry, and Mathematics for students at IB level, high school level, and school level. I am familiar with the European School system, International School System, and A-level.

I myself was among the top 3s during my high school days and since then I have a great experience tutoring. I would look into problems from the student's point of view. This enables me to know where they are having difficulty and then help them study nicely.

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.

As a dedicated tutor with over six years of experience, I specialize in teaching Mathematics, Physics, and Chemistry to students of all levels, from primary school to university. My academic background is robust, holding honors degrees from both the Faculty of Science and the Faculty of Medicine. This diverse educational experience has equipped me with a strong foundation in scientific principles and the analytical skills necessary for effective teaching. My tutoring journey began while I was still at university, where I was consistently ranked among the top of my class. This early start ignited my passion for education and set the stage for a fulfilling career in tutoring.

My teaching approach is carefully tailored to meet each student’s individual needs. I recognize that every learner has a unique style and pace, and I strive to adapt my methods accordingly. Whether a student requires in-depth explanations of complex theories or concise summaries of key concepts, I ensure that my lessons cater to their specific requirements. This flexibility allows me to build a strong foundation in core concepts while guiding students through practical problem-solving techniques that are essential for mastering the subjects.

In my lessons, I focus not only on helping students grasp the subject matter but also on developing critical thinking and analytical skills. I believe that understanding the "why" behind mathematical and scientific concepts is crucial for long-term retention and application. Therefore, I encourage students to engage in discussions, ask questions, and explore the material deeply. This interactive approach fosters a love for learning and promotes intellectual curiosity, which is vital for success in any academic endeavor.

I offer tutoring sessions in various formats to accommodate different preferences and circumstances. Students can choose in-person sessions at my location or opt for online tutoring using an interactive whiteboard and video platforms like Zoom or Skype. This modern setup provides a seamless learning experience that is just as effective as face-to-face instruction. My goal is to create an engaging and supportive environment where students feel comfortable and motivated to learn.

Over the years, I have had the privilege of witnessing many of my students achieve outstanding results, including grades of "Excellent," "Very Good," and "Good." This success is particularly rewarding when I see students who initially struggled make significant progress. By identifying and addressing their unique learning gaps, I help them develop the confidence and skills necessary to excel in their studies.

I am committed to empowering students with the tools they need to succeed in Mathematics, Physics, and Chemistry. My lessons are designed to demystify complex concepts and make them clear and accessible. I strive to instill a sense of accomplishment in each student, guiding them to reach their maximum potential.

In addition to academic support, I also emphasize the importance of cultivating a growth mindset. I encourage my students to view challenges as opportunities for growth, helping them develop resilience and perseverance that will serve them well beyond the classroom.

If you are seeking a dedicated tutor who can provide personalized support and foster academic excellence, I invite you to reach out. Whether you are a student looking to improve your grades or a parent seeking guidance for your child, I am here to help. Let’s embark on a journey of discovery and achievement together, ensuring that every student can excel in Mathematics, Physics, and Chemistry!

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!”
