my friends have a soft power DTV with Muay Thai classes. They can choose when they want to do their class. That could probably work around your working hours.
I study at ALA. I came in on a 60-day exemption, went straight to the school to apply and then I waited about 50-55 days then went to immigration for my ED Visa.
I’ve started classes at the end of April, 2h per day, 3 times a week. I also study by myself after class.
About six weeks in and I can get by ordering food and having basic conversations, get situated in time… whereas before starting I could only say "hello and thank you".
The beginner level at my school is 3.5 months, but I’m already using Thai in everyday life. It’s not perfect but I get a few words here and there when watching videos and listening to people talk.
It really depends on how much time you invest in learning and how much you practice.
en anglais ça se dit plutôt "middle name". Et de façon générale, même si on ne l’utilise pas souvent, dans les demandes officielles, c’est toujours plus prudent de mettre tous tes noms comme sur ton passeport. Mieux vaut trop que pas assez :)
