I’ve just started online classes with Prof. Ana Carolina & she is the absolute best! It’s my first time learning Portuguese and I was speaking full sentences in the first class. Obrigada!

Small classes, diverse accents, and engaging professors make Rio & Learn Online a fantastic choice! I've been thrilled with my experience at Rio & Learn Online so far. The small class sizes (around 1-3 others students) allow for personalized attention and plenty of opportunities to practice speaking. What's more, having different professors throughout the program exposes you to various accents, preparing you for real-world interactions. I opted for the full-time program, which involves 2 hours of daily learning from Monday to Friday. After just over 12 weeks, I can confidently say my Portuguese has improved dramatically. The professors are incredibly engaging and encourage students to utilize real-life examples, solidifying the learning process. While I'm only halfway through the program, I'm confident in recommending Rio & Learn Online to anyone seeking to learn Portuguese in a supportive and effective environment. I've gone from being a complete beginner (only knowing hi and bye) to holding conversations - and I'm excited to see how much further I can progress! I'll be back with another review after completing the program, but for now: Rio & Learn Online - highly recommended!

Après 3 semaines que je suis dans cette école et je peux déjà parler portugais. Certe avec des erreurs mais j'ai fait des progrès fulgurant. En plus, du Lundi au Vendredi l'ecole propose des activitées qu'il appelle "Rio Live" ce qui permet de visiter en même temps Rio tout en parlant Portugais et de rencontrer des gens😃 Toute l'équipe est genial et est prêts à aider si besoin 😁
I've been taking the group online courses with Rio&Learn for 2 months. They offer a fantastic way to learn Portuguese and get speaking practice if you don't live in Brazil. The teachers are engaging and are able to adjust their level of Portuguese to whatever level you are at. Obrigado!

C'est vraiment fantastique...RioAndLearn. Les cours de portugais...ça vaut vraiment la peine. Les cours ont lieu du lundi au vendredi, (de 9h à 13h) et en après midi, ce sont des activités libres en groupe. (Soccer de plage, volleyball , excursions, visites des lieux touristiques, etc) Vendredi soir, on est allé à Lapa, un quartier nocturne de Rio. C'est quelque chose à voir! Des rues bondées de monde, des orchestres, des discothèques...Allô les décibels! L'apprentissage du portugais se fait en immersion, aussi bien en salle de classe que dans les activités extérieures organisées par Rio&Learn. On est plongé dans la langue portugaise et la culture Brésilienne.... Obligé de parler portugais....🫡 Je le recommande. Pierre Pedro, Montréal, Canada
