I don't understand what was wrong. There are some things interpreters can't do. In high school, you had one or two interpreters all day. But the interpreters here work with many different students. Colleges and other schools after high school are different.
Interpreters specifically come for their assignment.
In high school, the interpreter would go with you to class and to the resource center, and maybe tutor you for class. Here, interpreters are not allowed or trained to be tutors. Oh, I see. It's MY responsibility. I can't depend on the interpreter.
