Chemistry Class (pH, electrochemistry, titration, redox, stoichiometry) - English

28 £ /h

Chemistry is a widespread subject in many schools, institutes and universities.

The first obstacle to overcome this subject is quantitative chemistry, an enormous examination full of notions such as pH, electrochemistry, titrations, redox, atomic and molecular orbitals, colligative properties, gas. I offer lessons on all these topics, both for exam preparation and for a test or class assignment.

I combine theory with practice, offering exercises I propose or carrying out those that you bring yourself.

Scientific Coaching: PhD, postdoctoral researcher and scientists

52 £ /h

Studying science or doing a PhD in science is particularly difficult and challenging. It is even more complicated considering that finding a job afterward is not easy.
I have been through a PhD in Physical Chemistry, abroad and far from my home country, so I can tell how difficult it is.
Why this class, then?

I want to share with you my experience as woman in science and support your efforts during the PhD or during the search for a new job, providing coaching class and support.

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.
