Profesor. con más de 18 años de experiencia da lecciones privadas en Matemáticas - Análisis - Matrices - Estadística - Álgebra - Geometría - Física - Mecánica - Electricidad - Química - Química Orgánica - Biología, Geología para programas franceses e internacionales.
Doy lecciones privadas en el sitio o en línea a través de una pizarra interactiva compartida equipada con bolígrafos de diferentes colores en los que cada uno de nosotros puede escribir, mecanografiar, corregir y mostrar el trabajo más que Zoom o Skype para comunicarnos. He estado practicando este método durante más de 6 años con este método muy modernizado y MUY CONFIABLE (es como si estuviéramos en el mismo lugar).
Los resultados de mis estudiantes y en particular los estudiantes de Terminale son excelentes TODOS en mención muy bien y algunos excelentes. Les doy a mis alumnos la técnica de trabajo para sacar las mejores notas.
TODOS LOS QUE INTENTAN ESTE MÉTODO PREFIEREN.
No dude en ponerse en contacto conmigo para obtener más información, responder en unos minutos hasta 12 horas como máximo.

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!
