Did my RCG course today. The man who was the instructor was very rude to non English background speakers. He was very impatient and if you make any noise he would yell at you. There was one lady who came from a non English background and needed help with the question. He yelled at her saying she can't ask anyone or he will fail her. Never in my life encounter someone so unhelpful at a course. I don't recommend anyone if you are not from an English background. Save yourself from abuse.
