Experienced professor graduated from the Faculty. of Sciences and the Fac. of Medicine of France, gives private lessons in Mathematics - Analysis - Matrices - Statistics - Algebra - Physics - Chemistry - Biology of French, Quebec CEGEP or International programs (in English) to students of secondary classes, Terminales, Brevet Concours and classes university preparatory courses for the 2022/2023 academic year.
So that I can help students who take CNED and those who prepare for the SAT exams.
The lessons will take place either at home or online using a specific, very modernized method, a shared interactive board equipped with writing tools where I can, with the student, write and correct homework by exposing them directly, in addition to Zoom or Skype to communicate (very practical method like at home).
Results of my Terminale students since 2015: mentions Very good, Good and Excellent.
Contact me for more details.

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 university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.

Ma méthode d’enseignement repose sur trois piliers :

1️⃣ Simplification des cours – Je rends les notions scientifiques faciles à comprendre en les expliquant de manière claire et progressive.

2️⃣ Supports visuels variés – J’utilise des présentations PPT, des schémas explicatifs et des documents illustrés pour rendre l’apprentissage plus vivant et concret.

3️⃣ Pratique adaptée – Chaque notion est consolidée par des exercices ciblés, adaptés au niveau et au rythme de l’élève.

💡 Mon objectif est d’offrir un apprentissage clair, motivant et efficace, en adaptant le contenu et le rythme aux besoins spécifiques de chaque apprenant, pour garantir une progression réelle et durable.

Chemistry is often taught as a series of facts to memorize, but at its heart, it's a beautiful and logical story about how the world works at the molecular level. As a master student of theoretical and computational chemistry, I don't just teach you what happens; I teach you the fundamental why.
This class is designed for students who want to truly understand chemistry, not just pass a test. Whether you're a high school student grappling with stoichiometry, an undergraduate diving into organic chemistry, or simply a curious mind wanting to understand the world around you, this course is for you. I believe that anyone can understand chemistry with the right guidance.
My goal is to be that guide. I'm here to help you, whether you're feeling lost in class, preparing for final exams, or starting a university course that feels overwhelming. I adapt to each student's unique needs and learning style.

I can help you master:
The Atom and Periodic Table: Understanding the building blocks.
Chemical Bonding: How and why atoms stick together.
Stoichiometry: Mastering mole calculations and chemical reactions.
Solutions and Concentration : Making sense of molarity and dilutions.
Acids, Bases, and pH : Demystifying protons and logarithms.
Thermodynamics and Kinetics: Understanding energy and reaction rates.

And more! Whether it's physical chemistry, organic chemistry, or inorganic chemistry, we can explore it together.
We'll work at your pace, fill in any gaps in your knowledge, and build your confidence step by step.
