I have a unpro Interpreter at my high school. I only have a one pro and unpro Interpreters. Pro is awesome, she did great job. She caught up everything and never missed! Well, some lol. She signs fast and clear! But other one isn't. She signs really slow and sometimes she mistaken signs. She would ask me two or three times to sign again! She can't catch up well, she behind like at least 6 or more words. I hardly understand her. I don't understand how High school hire her if she is not pro yet? She still in college. I having a hard time understand what going on each classes. Any tips?
