ALG World has uploaded a 3-part video from an advanced class. In the title it says 'Famous People' so I guess that is what the class was on.
I believe the students need to complete 200 hours for each level, so that means the students in the class have put in about 800 or more hours of ALG World Thai and understand 60% or more. The students are also allowed to speak Thai and you can hear some of them answering the teacher. Also, I think in the advanced levels there is only one teacher instead of two, which is what I see in this one.
If you don't understand Thai, the third video is the most interesting one.
