An exam is coming up and your child doesn't know where to start? Is the Baccalaureate or Brevet exam approaching and they lack method or confidence?
He knows the material but loses his composure when faced with an exercise?
He makes repetitive mistakes despite his revisions?
He doesn't know how to organize his revision?
There isn't enough time to review all the chapters?
Or does he simply want to prepare himself seriously to achieve better results?
I can help him organize his work, target his difficulties and train effectively.
I am a mathematics teacher with 15 years of teaching experience and hold a Master's degree in mathematics. I tutor middle and high school students, particularly in the French and Moroccan curricula.
🎯 Preparation tailored to the student's objective
Good preparation is not just about doing a lot of exercises.
First, we need to identify:
• concepts that are not mastered;
• errors that recur regularly;
• methods that the student does not yet know how to use;
• the priority chapters;
• the actual level of preparation.
Next, we implement a targeted and progressive approach.
📝 Preparation for tests and exams
Depending on the level and objective, we can work on:
• review of essential concepts;
• classic exercises and more complex exercises;
• the exam topics;
• problems requiring multiple steps of reasoning;
• the problem-solving methodology;
• drafting the solutions;
• time management;
• the analysis and correction of errors;
• the strategies to use when faced with different types of exercises.
For the Brevet or the Baccalaureate, we can also work from past exam papers to gradually familiarize the student with the exam format.
🔎 A method based on errors
An error is not simply something to be corrected.
It allows us to understand what is not yet mastered.
During the sessions, we therefore analyze the errors to determine their origin, then we repeat the method until the student is able to solve a similar exercise independently.
Understand → Practice → Identify errors → Correct → Repeat → Master
💻 Interactive online courses
The classes are held remotely using Google Meet and an interactive whiteboard.
The student works directly with me during the session. It's not simply a matter of looking at a solution: they must search, explain their reasoning and participate actively.
I can also send him screenshots of the work done during the session to facilitate revisions.
🏆 15 years of experience
I have worked with many students of varying levels and difficulties.
For my final year students who were tutored in mathematics, I achieved a 100% success rate in the Baccalaureate, with 75% obtaining a distinction of "Bien" or "Très Bien".
This experience allows me to adapt the work to the available time and the actual level of the student, especially when an exam is approaching.
👨‍🎓 For which students?
• College
• High school
• Second
• First
• Final year
• Preparation for the Brevet exam
• Preparation for the Baccalaureate
• Preparation for inspections
• Students needing a refresher course before an exam
The French and Moroccan programs are taken into account.
📩 An exam is coming up?
In your message, please tell me:
• the student's level;
• the type of examination or test;
• the date;
• the relevant chapters;
• the main difficulties encountered.
This will allow me to determine priorities and propose work that is adapted to the time available.
The goal is to prepare the student effectively, to correct their priority difficulties and to enable them to approach their exam with more method and confidence.

► EXPERT STATISTICS, DATA ANALYTICS, MACHINE LEARNING & AI TUTOR FROM SWITZERLAND
► UNIVERSITY, FOUNDATION, IB, A-LEVEL & INTERNATIONAL SCHOOL SUPPORT

I completed my Master’s degree in Business Information Systems at a Swiss University of Applied Sciences, where my academic background strongly combined mathematics, statistics, data analysis, analytical thinking and problem-solving. This technical and data-oriented foundation shaped the way I teach today: clearly, logically and with a strong focus on real understanding.

For many years, I have successfully supported students in Statistics, Data Analytics, Machine Learning and AI. My main focus is especially on Statistics — from basic descriptive statistics to advanced statistical methods, hypothesis testing, regression, probability distributions and interpretation of results.

I mainly use R for statistical analysis, data handling, visualisation and practical exercises. My goal is not only to help students calculate results, but to make sure they understand what the results mean and how to explain them correctly.

► STATISTICS, DATA ANALYTICS & AI SUPPORT

► STATISTICS & PROBABILITY
I help students understand descriptive statistics, probability, random variables, distributions, sampling, confidence intervals, hypothesis testing, p-values, correlation, regression and statistical interpretation. My lessons focus on explaining the logic behind each method, not just applying formulas.

► APPLIED STATISTICS WITH R
I support students in using R for statistical analysis, data cleaning, visualisation, hypothesis testing, regression models and interpretation of outputs. Students learn how to connect theory, calculation, code and real meaning step by step.

► QUANTITATIVE METHODS & RESEARCH STATISTICS
I help students with statistical methods used in business, economics, psychology, social sciences, science and university research. This includes choosing the correct test, understanding assumptions, interpreting results and presenting findings clearly.

► DATA ANALYTICS & DATA SCIENCE
I support students with data preparation, exploratory data analysis, visualisation, dashboards, summary statistics and practical interpretation. The focus is always on understanding the data and drawing meaningful conclusions.

► MACHINE LEARNING & AI FOUNDATIONS
For students working with modern data topics, I also provide support in the foundations of Machine Learning and AI, including regression, classification, clustering, model evaluation and practical applications. These topics are explained from a statistical point of view, so students understand the logic behind the models.

► UNIVERSITY, FOUNDATION & INTERNATIONAL COURSES
I support students in Statistics, Data Analytics, Business Analytics, Quantitative Methods, Econometrics, Research Methods and technical modules. I help with exam preparation, assignments, projects and practical data analysis tasks.

► HOW I TEACH

► I FOCUS ON REAL STATISTICAL UNDERSTANDING.
Statistics becomes much easier when students understand why a method is used, what the result means and how to interpret it correctly.

► I EXPLAIN FORMULAS STEP BY STEP.
Difficult formulas, tests and models are broken down into simple, logical parts so students can follow the reasoning clearly.

► I CONNECT THEORY WITH R PRACTICE.
Students learn not only the statistical theory, but also how to apply it in R, read the output and explain the result in proper academic language.

► I HELP STUDENTS CHOOSE THE RIGHT METHOD.
Many students struggle with deciding whether to use a t-test, chi-square test, ANOVA, regression or another method. I teach students how to recognise the correct approach from the question or dataset.

► I TRAIN INTERPRETATION AND EXAM TECHNIQUE.
Students learn how to structure statistical answers, write clear conclusions, explain p-values, interpret confidence intervals and present results professionally.

► I ADAPT EVERY LESSON TO THE STUDENT.
Some students need help with theory, others with R coding, assignments, research projects or exam preparation. I adjust every lesson to the student’s exact course, level and goals.

► YEARS OF EXPERIENCE WITH STATISTICS, DATA & UNIVERSITY STUDENTS

Over the years, I have successfully supported students from demanding academic programmes, helping them strengthen their statistical understanding, improve their analytical thinking and achieve excellent progress in Statistics, Data Analytics, Machine Learning and AI.

B- PERSONALIZED TUTORING: LEARNING HOW TO REASON
Machine learning and artificial intelligence become much more accessible when mathematics, algorithms, Python code, data, and real-world applications are clearly connected.

My lessons help you move beyond simply copying code or using models as “black boxes.” You will learn how to define the problem correctly, prepare the data, select an appropriate algorithm, understand how it works, train and evaluate the model, diagnose errors, improve performance, and interpret results rigorously and responsibly.

Each lesson is personalized according to your current level, mathematical background, programming experience, dataset, university work, research project, interview preparation, or professional objective. We begin by identifying your existing knowledge, software environment, expected outcomes, and main conceptual or technical difficulties. We then establish a structured learning plan.

The first lesson combines a discussion of your background, objectives, and tutoring needs; an initial assessment of your current knowledge; personalized planning and organization of future sessions; and a short trial lesson to determine the most effective learning approach.

A typical session may include conceptual explanation, development of mathematical intuition, live coding, guided implementation, model evaluation, technical problem solving, and a concise summary of the next steps.

You may work with your own dataset, university assignment, research project, or professional problem, provided that confidential information is handled appropriately. I can also provide structured examples and datasets suited to your level.

My goal is not simply to help you run an algorithm. It is to help you understand why it is appropriate, how it learns from data, how to evaluate it correctly, why it may fail, and how to build a reliable, interpretable, and scientifically rigorous solution.
