1st place nationally in Lebanon in 2012 and 2015, then 3rd place worldwide in India in 2016, I now offer mental calculation courses on abacus for children. The abacus is an ancient calculating tool, used long before calculators. I learned this method as a child through the UCMAS program, and it has been incredibly beneficial. Beyond mental arithmetic, it allowed me to stand out from other students and feel particularly comfortable in elementary, middle, and high school, especially in subjects that require concentration, logic, and a good memory, whether in mathematics, science, history, or other subjects where it's necessary to retain information and structure one's thoughts. What I love about this method is that it doesn't just develop calculation speed. It also helps strengthen concentration, memory, visualization, logic, self-confidence, and comfort with numbers. For many children, it's a real foundation that helps them far beyond the sessions, in how they learn, think, and approach school with more confidence. Each child has their own way of understanding. My role is to adapt to them, to patiently pass on this method, and to make learning stimulating, progressive, and accessible. Since this method requires regularity to give real results, I prefer support over several sessions, with progression and training between lessons. Location / format: Arpajon, Paris and surrounding areas, or video conferencing.

Many students lose confidence in math during the school year due to stress, fast-paced classes, or gaps in understanding. This summer program helps students rebuild confidence, strengthen fundamentals, and prepare calmly for the next academic year. This program is designed for students who want to: - catch up on difficult topics - prepare for the next school year - improve grades and confidence - build strong problem-solving skills - prepare for exams and entrance tests Lessons are adapted individually for each student and explained step-by-step in a clear and patient way. I focus not only on solving exercises, but also on helping students truly understand concepts and think independently. After the first lesson, I create a personalized study plan based on the student’s level, goals, and areas that need improvement. Lessons are interactive, organized, and supportive, with homework and additional practice materials when needed. Suitable for: - Middle school students - High school students - IB students - Students preparing for exams ! ! ! Summer availability is limited to ensure individual attention for each student.

I hold a PhD in Mechanical Engineering and currently work as a post-doctoral researcher in the Aerospace Engineering Faculty at TU Delft (Delft University of Technology). Key topics that I teach for this course include: • Calculus: Differentiation & integration, Multivariable calculus • Linear Algebra: Matrices, vectors, systems of equations, Eigenvalues and eigenvectors • Differential Equations: First- and second-order ODEs, Laplace transforms • Complex Numbers: Polar form, Euler’s formula • Vector Calculus: Gradient, divergence, curl, Line and surface integrals • Series & Transforms: Taylor series, Fourier series I understand that not all teachers excel in teaching Engineering and Mathematics courses and explaining their importance to students. Courses with strong mathematical backgrounds may become boring for students who lack a solid mathematical basis. To address this, I take a student-centered approach, starting from the basics to actively engage all students, including those with weaker mathematical backgrounds. I also provide practical examples to demonstrate the real-world significance of what they are learning, inspiring and fostering their interest in the subject matter. If you have any additional questions before starting a class, please feel free to ask me. I am here to assist! :)

I provide high-level instruction in university mathematics and statistics for students in STEM, Economics, Engineering, and Data Science programs. This class is designed for students who require conceptual depth, mathematical rigor, and practical analytical skills, not surface-level tutoring. I teach core university subjects including Calculus I–III, Linear Algebra, Differential Equations, Probability, and Statistics, with a strong emphasis on understanding how mathematical theory is applied in real academic and research contexts. My approach goes beyond standard problem-solving. I help students: develop mathematical reasoning and proof-based thinking connect abstract theory to applied models and real data understand how mathematics underpins research papers and empirical studies interpret formulas, graphs, and statistical results critically move confidently between theory, computation, and interpretation In addition to coursework support, I assist students with: statistical analysis of research data understanding and reproducing methods used in academic papers regression analysis, probability models, and data interpretation preparing mathematical and statistical sections of research projects With extensive experience teaching at both international universities and research-oriented environments, including work as a Math and Statistics tutor at the University of Wisconsin–Madison, I understand the expectations placed on university students and researchers. I help students bridge the gap between lectures and independent academic work. Sessions are structured, intellectually demanding, and personalized. I work with motivated undergraduate and graduate students, as well as adult learners who need mathematics for research, professional growth, or advanced study. Sincerely, Leila
