Many students lose confidence in math over the school year - not from lack of ability, but from pace, gaps, or one bad unit that never got resolved. This summer program (through mid-September) is built to fix that before the new year starts, not just review generally.
I work with middle and high school students, including IB, to close specific gaps not a broad refresher, but targeted work on exactly what's holding a student back. I bring the same structured, evidence-based approach I use with my university-admission students: identify precisely what's missing, build a plan around it, and track real progress, not just hours logged.
Best for students who want a calm, focused reset before the new academic year begins not for open-ended tutoring with no target

Students following American-style academic pathways often need very specific support. They are not only learning Mathematics, Science or Statistics; they are also preparing for systems where GPA, course grades, AP results, SAT/ACT scores and university applications can all matter at the same time. American High School courses, AP exams, SAT and ACT preparation require strong foundations, fast problem-solving, clear reasoning and regular practice with the right type of questions.
This is exactly where I help.

→ I am a Switzerland-based tutor with a strong academic background in Mathematics, Statistics, Data Science, Artificial Intelligence and technical sciences. My education in the Swiss higher education system has shaped the way I teach: precise, structured, logical and focused on real understanding.

→ Over the years, I have taught many students from international schools, American-style school programmes, British curriculum schools and Swiss schools. Through this experience, I have become very familiar with the common difficulties students face in SAT Math, ACT Math, ACT Science, AP Calculus, AP Statistics, AP Physics, AP Chemistry and American High School Math and Science courses.

→ I also work with previous exam papers, official-style practice questions, AP-style exercises, SAT/ACT-style questions and topic-based material. This allows my lessons to be highly exam-focused. Students do not only learn the theory; they practice the type of questions they are likely to meet in school tests, AP exams, SAT/ACT exams and final assessments.

→ MY MAIN TEACHING FOCUS

→ I mainly support students in SAT Math, ACT Math, ACT Science, AP Calculus AB, AP Calculus BC, AP Statistics, AP Physics, AP Chemistry and American High School Math and Science courses.

→ This includes Algebra 1, Geometry, Algebra 2, Precalculus, Calculus, Biology, Chemistry, Physics, Statistics, Probability, Functions, Graphs, Trigonometry, Vectors, Mechanics, Electricity, Waves, Stoichiometry, Equilibrium, Acids and Bases, Kinetics and Electrochemistry.

→ I also support students who are preparing for university entrance exams, school-specific assessments, placement tests or international university applications where strong Mathematics and Science results are important.

→ SPECIFIC SUPPORT FOR SAT, ACT, AP AND AMERICAN HIGH SCHOOL COURSES

For SAT Math, I help students improve speed, accuracy and confidence. The main focus is on Algebra, functions, quadratic equations, systems of equations, geometry, trigonometry, statistics, probability and word problems. SAT Math questions often test familiar topics in unfamiliar ways, so students need strong foundations and smart exam technique. I teach students how to recognize patterns, avoid traps and solve questions efficiently under time pressure.

→ For ACT Math, I support students with the wide range of topics tested in the exam. ACT Math is fast, broad and time-sensitive, so students need both knowledge and strategy. I help students revise key areas such as algebra, geometry, functions, trigonometry, probability and statistics, while also improving timing, accuracy and decision-making during the exam.

→ For ACT Science, I focus on graph reading, table interpretation, experimental reasoning and scientific data analysis. Many students think ACT Science is mainly about memorizing Biology, Chemistry or Physics facts, but in reality it tests how quickly and accurately students can understand scientific information. I train students to read graphs, compare data, understand experiments and answer questions under time pressure.

→ For AP Calculus AB, I support students with limits, derivatives, applications of differentiation, integrals, applications of integration and basic differential equations. I help students understand the logic behind calculus, not only memorize rules. Students learn how to connect graphs, formulas, word problems and written explanations.

→ For AP Calculus BC, I cover all AP Calculus AB topics and also support students with more advanced topics such as sequences, series, convergence tests, Taylor series, parametric equations, polar functions and advanced integration ideas. AP Calculus BC requires strong algebra, clear thinking and regular exam-style practice.

→ For AP Statistics, I help students with descriptive statistics, probability, distributions, sampling, experimental design, confidence intervals, hypothesis testing, regression and interpretation of results. AP Statistics is not only about calculations; students also need to explain results clearly in words. I help them write answers in the correct statistical language.

→ For AP Physics, I support students with mechanics, forces, energy, momentum, circular motion, rotation, electricity, circuits, waves and other topics depending on the exact AP Physics course. The focus is on understanding concepts, choosing the correct formula, using units properly and explaining physical reasoning clearly.

→ For AP Chemistry, I help students with stoichiometry, atomic structure, bonding, chemical reactions, thermodynamics, equilibrium, acids and bases, kinetics and electrochemistry. Students often struggle because Chemistry combines theory, formulas and multi-step calculations. I break the topic down clearly and practice exam-style questions until the method becomes understandable.

→ WHY EXPERIENCE WITH THESE EXAMS MATTERS

→ Every American-style exam and course has its own logic. SAT Math often tests simple topics in clever ways and rewards speed, accuracy and pattern recognition. ACT Math is broad and time-pressured, so students need both knowledge and fast decision-making. ACT Science is not mainly about memorizing science facts; it focuses on graphs, tables, experiments, data interpretation and scientific reasoning.

→ AP exams are different again. AP Calculus requires deep understanding of limits, derivatives, integrals and applications. AP Statistics requires careful interpretation, correct language and clear reasoning. AP Physics and AP Chemistry require students to connect concepts with calculations and explain their thinking clearly.

→ Because I have taught many students preparing for these subjects, I understand the difference between knowing the topic and being able to perform well under exam conditions. A student may understand the lesson in school, but still lose marks because the method is incomplete, the explanation is unclear, the calculation is rushed, or the question is misunderstood.

→ That is why my lessons are not random. I use a structured system: first we build the foundation, then we practice topic-based questions, and then we move towards mixed exam-style problems. This helps students become more confident, faster and more independent.

Videoconference classes for students in grades 6, 5, 4 and 3 of the French program, both in France and in the network of French schools abroad.

In middle school, difficulties in math rarely stem from the current chapter. They almost always originate from a foundation established two or three years earlier: fractions, proportionality, algebraic expressions. As long as these concepts aren't revisited, each new chapter exacerbates the situation. My work begins by identifying this missing foundation.

Master's degree in Operations Research (applied mathematics), more than five years of private tutoring for students in the AEFE and Mission laïque networks, in both public and private institutions.

What we are working on

Numbers, fractions, algebraic expressions, equations
Proportionality, percentages, statistics
Plane geometry, theorems of Thales and Pythagoras, transformations
Preparation for the patent
Working method: read a problem statement, choose an approach, check a result

The process

Initial assessment during the first sessions, a catch-up plan, followed by a regular weekly schedule. I align with the classroom teacher's approach and provide exercises between sessions. A monthly written progress report is available for parents who wish to receive it.

I also offer pre-start preparation sessions, to get a head start on the year rather than being late.

Courses in French, English or Arabic.
