Hello,
Previously a double degree student in computer science and mathematics at Sorbonne Paris Nord University (formerly Paris 13).
Student in applied mathematics engineering at ENSTA PARIS and ENSAE PARIS in double degree
I can give tutoring in mathematics so that in physics and chemistry, the main advantage of my classes is that they contain tips that improve the student's response to an exercise, a very good course that aims the essential without forgetting the important details, and a follow-up of the evolution of the student through the tests of progression and exercises since the exercises of application until the starry exercises.
Apart from my good teaching approach, I have great skills in mathematics and physics chemistry besides I am the first dz my class in mathematics in double license.
Through my private lessons I want not only to transmit my knowledge, but also the good methods and reflexes before tests or exercises.
Cordially.

If you read this BRAVO, you have just taken a big step towards improving your level in Maths, Physics and / or Chemistry.

Holder of a license in Applied Physics from the University of Sciences and Technologies of Montpellier and a Master in Medical Life Engineering from the University of Paris Descartes, I offer to accompany you throughout the year or for more punctual sessions (Preparation for exams or questions) or for awakening to basic sciences. Holder of the Certificate of Aptitude for Functions of Facilitator (BAFA) I am also a pedagogue and know how to adapt to your possibilities to find your way of learning and your pace of work. There are many ways to understand these subjects but there is always one that will suit us best.

During my three years of Applied Physics my teachers taught me intuitive techniques to preview the results, know what to find and where we are going. I therefore suggest that you explain the classic, institutional way, but also give you the secrets that we do not teach.

For more information, do not hesitate to contact me.

I teach mathematics, physics and chemistry from elementary to high school: I put much more emphasis on methodology and confidence building. This makes it easier for students to approach the material.

I support students throughout the year with personalized follow-up for each student: methodology, exam preparation, optimization and time management.

Homework help, revisions, preparation of revision sheets, exam corrections, personalized advice.

Depending on the level, the difficulties and the needs of my students, I set up a program to assess their progress. Some need more lessons to consolidate the basics while others master the course and they need more practice exercises. Once the students have mastered the course and the application exercises, we work through specific tests, self-confidence and time management, making it easier to tackle exams in class.
I have students who were below average and who became good at it; others who were good but lacked confidence and subsequently became excellent.

I am available immediately for regular or punctual courses.

🧪 IB Chemistry Apprentice Lesson Plan

Topic: The Electromagnetic Spectrum
Level: IB Year 1 (Apprentice)
Duration: 60 minutes

Lesson Objectives

By the end of this lesson, students should be able to:

‣ Describe the electromagnetic spectrum and identify its different regions.
‣ Understand and apply the equation c = fλ.
‣ Differentiate between a continuous spectrum and a line spectrum.
‣ Explain the concept of quantized energy in atoms.

Lesson Outline

Introduction (0–5 minutes)
Start the lesson by asking students a few engaging questions:
What are some examples of invisible light or radiation around us?
Why do we wear sunscreen?

Allow brief responses, then explain that all of these examples are part of the electromagnetic spectrum, which we will study today.

Teaching Phase 1 – Overview of the Electromagnetic Spectrum (5–15 minutes)
Introduce the electromagnetic spectrum. Explain that it is a range of all electromagnetic waves, which vary by frequency and wavelength. Emphasize that all electromagnetic waves travel at the same speed in a vacuum – the speed of light, c = 3.00 × 108 m/s.
Key formula to introduce: c = fλ, where:
c = speed of light
f = frequency (Hz)
λ = wavelength (m)

Point out that high-frequency waves have short wavelengths and higher energy (like gamma rays), while low-frequency waves have long wavelengths and lower energy (like radio waves). Display a spectrum diagram showing the range from radio to gamma rays, with visible light in the center.

Teaching Phase 2 – Spectrum Types: Continuous vs. Line Spectrum (15–25 minutes)
Explain the difference between continuous and line spectra.

A continuous spectrum** contains all wavelengths in a range, like a rainbow produced when white light passes through a prism.
A line spectrum** shows only specific wavelengths or frequencies. This happens when excited electrons fall back to lower energy levels and release photons of specific energies.
Explain that energy is **quantized**—electrons cannot have just any amount of energy; only specific values are allowed. Use the helium line spectrum image as an example.

Real-World Examples and Class Discussion (35–45 minutes)
Give students three practical examples and discuss their uses:

1. Microwaves – Used in cooking and communications.
2. Ultraviolet (UV) rays – Cause sunburn; used in sterilizing equipment.
3. Gamma rays– Used in cancer treatment and in detecting radioactive materials.

Ask students:
Where do you see or use electromagnetic waves in your daily life?
Encourage short contributions to reinforce understanding.

Student Exercises (45–55 minutes)
Have students complete these three questions individually:

1. A wave has a frequency of 6.0 × 1014 Hz. Calculate its wavelength using c = 3.00 × 108 m/s.
2. Explain the difference between a continuous and line spectrum, with an example of each.
3. Why are gamma rays more dangerous to humans than radio waves?

Wrap-Up and Recap (55–60 minutes)
Call on a few students to briefly summarize one key thing they learned.

I offer personalized academic support in Mathematics, Physics, Chemistry, and Biology for secondary and high-school students. Whether the goal is to strengthen fundamental concepts, overcome specific difficulties, improve problem-solving skills, prepare for tests and exams, or simply gain confidence in a subject, each lesson is adapted to the student’s curriculum, level, objectives, and learning pace.

Learning science is about much more than memorizing formulas, definitions, and procedures. My approach focuses first on understanding: identifying what really matters, connecting different concepts, developing logical reasoning, and learning how to approach a problem step by step. The objective is not only to improve academic results, but also to help students become more confident, curious, and independent learners.

Depending on the student’s level and curriculum, I can provide support in:

¤ Mathematics — algebra, equations and inequalities, functions, sequences, geometry, trigonometry, vectors, limits, derivatives, integrals, probability and statistics
¤ Physics — mechanics, motion and forces, energy, electricity, electromagnetism, waves, optics, thermodynamics, atomic and modern physics
¤ Chemistry — atomic structure, chemical bonding, reactions, stoichiometry, solutions and concentrations, acids and bases, oxidation-reduction, thermochemistry, kinetics and introductory organic chemistry
¤ Biology — cell biology, genetics and DNA, molecular biology, human physiology, reproduction, evolution, ecology and basic biochemistry

I hold a PhD in Physics and have a broad academic background in physics, mathematics, applied sciences, and experimental research. My scientific training allows me to connect concepts across different subjects and, whenever useful, relate what students learn in class to concrete examples, experiments, technology, and real scientific applications.

Lessons are adapted to the student’s own school program and materials and can be provided in English or French, with explanations in Arabic whenever helpful.
