From 29.15 $ /h

A clear, practical methodology adapted to each student (ESO and Bachillerato). I begin with an initial assessment and focus on deep understanding rather than memorization, using simple explanations, visual diagrams, and guided practice with exam-style exercises.
I am fully committed to each student's progress, offering serious, consistent, and personalized support. I believe in well-directed challenges: combining discipline, clarity, and support so that students gain confidence and sustainably improve their results. My goal: for you to understand, pass, and gain confidence.

I have a degree in Physics with 6 years of experience in IES. My methodology is quite good given that last year, nobody failed and those who took the Selectividad, got the necessary grade for their studies.
In the case of students who wish to access FP, I have made a summary of all the entrance exams. It was one of the subjects I taught at an IES.
The time available for each student may vary slightly depending on where the student lives, because I don't mind traveling, but I have my work commitments. Even if I can't show up on Saturday to Sunday nights, I could do it online in the early hours of that night.

I am a qualified engineer from Arts et Métiers ParisTech and followed a preparatory class, accumulating more than 10 years of experience as a private mathematics teacher. My goal is to help your child reach their full academic potential in mathematics and develop skills that will prepare them for a bright future.

Why choose my courses?

Would you like your child to:

Significantly improve your results in mathematics/physics-chemistry?
Join a selective curriculum?
Become independent and confident in your abilities?
Over the last 5 years, I have had the privilege of supporting more than 30 French students, from middle school (sixth, fifth, fourth, third) to high school (second, first, terminale), towards academic success. My students obtained good averages, passed the certificate, the baccalaureate and the preparatory classes, while strengthening their self-confidence.

My teaching method in 3 steps:

Short term: Immediate improvement in average by assimilating the course and preparing for assessments. This includes assimilating the course, taking notes, practicing standard exercises, anticipating teachers' expectations and test questions, as well as acquiring writing methods.

Medium term: Integration of reasoning and working methods. Your child will learn to work regularly in this order: assimilation, training exercises, preparation for assessments and analysis of results.

Long term: Establishing clear goals, building the steps to achieve them, realizing the SIMPLICITY of mathematics, building confidence in your abilities and unlocking your child's potential.

Details of the formula:

One to two sessions of 1h30/2h per week to assimilate the course and prepare for the evaluations.
Classes delivered via Google Meet for effective online learning.
Use of a virtual whiteboard to facilitate the assimilation of concepts.
Access to an online library including 10 mathematics reference books.
Over 1000 online exercises to strengthen math skills.

I am a second-year Biomedicine student and I teach reinforcement classes in mathematics, language (Spanish, Catalan and English), biology, physics and chemistry for Primary and ESO. I adapt to the student's pace and study method and the syllabus taught in class.

Rémi

Student at the ENS in Paris, and questioner in preparatory classes, I decided to give physics-chemistry lessons to pass on what talented teachers have taught me and which I consider effective in order to help new students to better understand, learn, and pass their exams.

Together we will work on the lessons as well as classic exercises in order to both understand and manipulate the key notions and concepts in the program.

Understanding, method, efficiency, are the key points of my approach. I will adapt to each person's level, and we will be able to go back to the basics as well as go in-depth with the courses and prepare for the most selective competitions.

Give real meaning to the course, to the formulas, to the calculations, to make them your own, to have a perspective on the results, to know how to present them clearly, to understand the logic of the exercises, all these notions are all points evaluated in the exams/competitions that we will prepare together.

Courses possible in Barcelona (preferably in the city) or by video

Hello!
I am a student in France at AgroParisTech, before that I did two years of BCPST preparation in Saint Louis. I have been giving private lessons for 4 years, particularly to students with difficulties.
I live in French but I am also Italian and I lived in England, so I can give my lessons in different languages.

I give private lessons in lambada-oriental dance which is a mix of lambada (dance of Brazilian origin) and oriental dance (Egyptian dance).
These are the 2 most sensual dances among the existing dances.

The goal is to allow women to reconnect with their bodies, to regain self-confidence, to rediscover their feminine power.

Dance is an incredible tool for this. Performing steps to music allows us to forget for a moment what we are "missing" and focus on what brings us well-being.
By letting go we obtain magic!

This is how I work:
- learning basic steps
- learning typical technical movements
- learning movements that highlight femininity.
- put into practice in a choreography

I give either private lessons at home or group lessons at the beach. I adapt to demand

A course to learn and reinforce the topics covered in class. I have a C1 level in English and experience teaching. I adapt to the student without any problem. I'm a university student majoring in pharmacy, so I'm particularly good at chemistry, but I'm familiar with all types of secondary school and science baccalaureate subjects. The course would begin by assessing the student's level and building on what's been taught in their classes.

Candela

Learning math and chemistry. Two important subjects in the sciences. They are dense and sometimes complicated subjects, but it all depends on how they are explained and understood. That's why in my classes I try to make the class dynamic, adapting to the students' needs to try to achieve their maximum potential in the subject.
