I am not sure. I have not studied in Bunka before. My friends say there are conversational classes which focus only on speaking. Are these classes geared more towards intermediate or advanced learners? Is it Casual speaking or Formal speaking?
That is their Pre-Advanced and Advanced classes. I attended their Pre-advanced classes before.
1.5 hours / 10-16 students/ the teacher goes around asking the 10-16 students a question and then the student will answer. If the student cannot answer within x mins/secs, the teacher will jump to the next person, etc....
If the teacher feels that you cannot promote to the next level, you will be stuck there. Some of my students were stuck for about 1 year at the same level. But that doesn't mean that ppl in the last level of pre-advanced can speak well.
It depends on the teacher whether they want to do casual/formal speaking.
Conversation after N3 is really boil down to ur own effort. Watch more dramas and try to mimic the actors. Sing more karaoke?
