Mathematics courses given by pre-PhD math students
Mathematics is a very important subject in the schools and even in the universities. As a math-major student, I have a good knowledge of math. I could offer courses for students preparing for exams in the schools, or possibly the math olympiads. I would also be happy to give more advanced courses for students who want to know more about modern mathematics, which might also be useful for high school or college-entrance exams.

English language courses for under 18s (0-18 years)
English is a Germanic language originating in England that over the centuries has become one of the most widely spoken and influential languages in the world. Today, it is the primary language of international communication, business, science, technology, popular culture, and diplomatic exchanges. Some characteristics of English: Global language: English is spoken by approximately 1.5 billion people worldwide, either as a native or second language. It is the official or dominant language in more than 50 countries. Ease of learning: Compared to other languages, English has a relatively simple grammar. It has no grammatical gender for nouns, and verbs are often less complex in terms of conjugation. Richness of vocabulary: English is a very flexible language, having borrowed words from many other languages such as French, German, Latin or Arabic, which gives it a richness of vocabulary. Language of popular culture: It is the dominant language in film, music, literature, and media. Most of the world's major popular films, series, songs, and books are in English. Language of innovation: In the technology, scientific research and innovation sectors, English is often the primary language used in publications and conferences. In short, English is much more than just a means of communication. It is a living and evolving language that plays a key role in uniting and connecting people across continents. Learning English is an essential skill in our modern world.

Learning Japanese for Traveling and conversation with japanese.
Are you planning a trip to Japan? The truth is, most Japanese people don’t speak much English. While they may try to communicate using a few words, knowing even a little Japanese can be incredibly helpful! It will also make them happy and even more welcoming. In this class, I will focus on practical conversation, based on my experience as a tour guide. We’ll cover essential Japanese phrases that my guests often wanted to learn while traveling. With this knowledge, you’ll be able to enjoy conversations with locals, creating unforgettable memories on your trip to Japan.

What happened? Very short, I promise: I was walking down the street two years ago, from just opposite this private school, and I thought myself: well, you might enter this place and see. I like English language very much... and the UK,... but I don' t have a poster of the Queen on my bedroom's wall. It was a sort of a blind date. And there she was: her smile, her diligence, effectiveness. Eva listened to me. And after two weeks she was texting me for a class. Please, Xavier, can you cover for some classes? And here I am. English Studio, Academy of English in Barcelona, where I used to be a teacher until Covid 19 knocked at the door of our lives, and teachers and students had to be at home.

Gavin
Cours d'anglais particuliers à Paris (présentiel ou EAD)
Hello ! Je m'appelle Gavin et j'ai 25 ans. Je viens de Seattle (Etats-Unis) et j'ai un Master en littérature anglaise et j’ai un certificat TEFL. Ce que je peux vous offrir : - Cours pour adultes et adolescents adaptés à votre niveau et à vos objectifs (de B1 à C2) - Cours de préparation à l'IELTS, CAE, TOEFL et autres examens - Cours de conversation - Business English (l'anglais des affaires) - English for Academic Purposes (l'anglais à des fins académiques) Je vais vous apprendre comment l'anglais est parlé et utilisé dans des situations réelles et quotidiennes. En nous concentrant sur les quatre compétences (lire, écrire, parler et écouter), nous pratiquerons des techniques de conversation tout en affinant votre grammaire, vocabulaire et prononciation. Le contenu peut porter sur des sujets que vous intéressent, qu'il s'agisse de petites conversations, de littérature, de cinéma, de politique ou de vos devoirs d'anglais. Quoi qu'il en soit, l'objectif principal de nos cours sera normalement de parler et d'écouter, mais je vous encouragerai toujours à vous exposer à autant d'anglais que possible en dehors des cours, que ce soit en regardant YouTube en anglais ou en lisant un journal. Normalement, les exercices de grammaire, de vocabulaire et d'écriture seront faits à la maison, sauf indication contraire de votre part. Je ne vous dirai pas « c'est comme ça ». Si vous voulez travailler sur votre grammaire, je serai heureux de vous aider à travers des explications et des exercices significatifs spécialement choisis pour vous, votre niveau et le type d'apprenant que vous êtes. Nous pouvons organiser des cours chez moi dans le 14ème arrondissement, en ligne via Zoom, à votre domicile ou encore dans un café si vous voulez. I look forward to hearing from you and to a successful collaboration ! Gavin
