What are the advantages ?
Undoubtedly, the first advantage is the ability to simulate a classroom without going through the school attendance process. This formula is particularly recommended for homeschooling
Secondly, sociability. Students interact with each other, help each other, and work together - and, depending on whether they know each other or not, group tutoring can strengthen their desire to do other activities together (e.g. sports). Some subjects lend themselves especially well to tutoring in mini-groups: modern languages, scientific subjects (NB for experiments, you need to have certain equipment), exam preparation, etc. For example, if you are in your final year of school and you are preparing for exams, it can be very advantageous to take a support course in a mini-group. Your fellow students can give objective assessments of your work and can discuss it constructively, and they can do likewise for your preparation for the International Baccalaureate or A-Levels. In short, the possibilities are endless.
Last but not least, group tutoring helps reduce costs. Instead of paying for a particular lesson for your child, the payment for the lesson is split between several parents, thus making the lesson more economically accessible.
