From 0.01 Fr /h

Teaching science is a way of teaching how to look at the world and reflect on it, from an open, investigative, critical attitude and permanent reflection on one's own practices. Biology is the science that studies life, on the other hand, Chemistry studies the structure, composition and properties of matter. The educational role of Biology wants, on the one hand, to expand and deepen knowledge about the basic mechanisms that govern the living world, for which students must have knowledge of the morphological and physiological structure and functioning of the various levels of organization. On the other hand, it is about promoting a research attitude based on the analysis and practice of the techniques and procedures that have allowed progress in these scientific fields. And, finally, it is about assessing the social or personal, ethical or economic implications of new discoveries in biology and knowing their main applications.
Therefore, you will learn to understand the nature of Biology and its limitations, as well as its complex interactions with technology and society, valuing the need to work to achieve an improvement in current living conditions.
This course offers academic support for all educational levels.

Physics and chemistry are the gateway to understanding all sciences, as a science student you will need to be able to sort through the many complex features to become a true student scientist with a critical and curious mind. That's why I designed this course to help students prepare for their exams and the next school year to fill in the gaps they have in math and science.
I would like to inform you that I am a young researcher and I can also help you to acquire basic knowledge of Microsoft Office and other essential software for your career.

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.

I am ready to share my passion and guide each student towards excellence and success in the field of science and organic chemistry and in studies in general, as I work as a student advisor in an international institution. In addition, I have excellent communication and presentation skills and am patient and calm when teaching. In addition, I constantly follow up on my students' progress and regularly evaluate their understanding through continuous solution of objective questions, as I care more about understanding than memorization. On the other hand, I also maintain good follow-up with parents. My teaching approach is directed towards achieving the highest results, with a focus on helping students understand and master information.

For university students or master's and doctoral students, I teach the course of natural product chemistry or phytochemistry. In this course, 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 devices, spectroscopy, mass spectrometry and magnetic resonance analysis. 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 methods that are carried out in the laboratory to conduct toxicity, antioxidant and diabetes analyses, etc.

Finally, "for those interested in scientific research" there is a course dedicated to knowing what scientific research is, how to choose a research point, how to write scientific research and how to find the appropriate journal for publication and everything related to this topic.

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 chemistry curricula.

With my qualifications and experiences, as I hold a master's degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other postgraduate certificates and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mundus organization affiliated with the European Union.
