I have done many different types of French courses before over the years and I often found them frustrating. Group sessions are often ineffective because there are always students who dominate the class and teachers often can't handle this effectively, meaning there is not much benefit to the rest of the class.
Individual classes also can be highly ineffective if they are not carefully structured and designed to lead to progress. When I first met Isabelle, I was struck by her professionalism and no nonsense approach and agreed to give her online classes through Prêt à Parler a try. After 2 months with one of her online teachers, I can honestly say that this is the best approach I've experienced to date. The classes take place using Zoom and you can do them at any time of the day wherever you are, which means there is no time wasted in getting to class, chatting to other students, etc. Every minute counts.
The teacher is very professional and uses a structured lesson plan - to help me focus on improving my business French. The classes have been very effective in improving my vocabulary, grammar and fluency in conversation. The system works very efficiently - the teacher takes notes online on a shared screen and you can view the lesson plan. In this way, the teacher takes all the notes and you receive a pdf with all the notes, as well as the video recording after each lesson. You also get set homework for the next course. Depending on your package, you get access to an online learning program of practical every day French to use in your own time. This is by far the most professional and effective French learning I've experienced in and outside of France, including some of the well-known language schools. I have no hesitation in recommending Prêt a Parler to anyone who is serious about learning to speak French.
