How many classes does it take to learn to speak Arabic well?

First of all, the frequency of Arabic lessons required to speak Arabic correctly and fluently varies from student to student, teacher to teacher, and depending on your goals.
Depending on your objectives, your level and your teacher, the frequency of the necessary classes will vary.
However, what really matters for optimal learning is having motivation, time, budget and stimulation of your cognitive skills. Cognitive ability varies from student to student and we are all different when it comes to language learning. Thus, it will take some a year of classes to internalize what it takes for others three years.
For example, a student who already speaks English, German or French will probably learn faster than a person who is new to Arabic and who does not know a language other than their mother tongue. Furthermore, there is a link between playing an instrument and language learning: a musician (pianist, guitarist, flutist, violinist, etc.) can learn a language more quickly than a student who does not play any instrument.
For introductory Arabic classes, one hour a week will suffice. As for the advanced classes, to improve your grades at university or to acquire a correct level in Arabic, we recommend two hours of class a week. Finally, in terms of intensive courses, they are usually between five and ten hours per week.
It all depends on the objectives set by the student. They are the ones who will mark the personal volume of work and the level of investment.
A good Arabic teacher will make you want to improve, which you will achieve if he teaches you both cultured Arabic and a few strokes of dialect Arabic. If you also put into practice an effective learning method, you will need fewer Arabic lessons than with a teacher who does not have one. How many classes does it take to learn to speak Arabic well?
