Daughter can't copy from the board fast enough and the notebook answers are what get tested

In her class 5 section the teachers write question-answers on the board, the children copy them into notebooks, and those answers are what come in the tests, often word for word. She copies slowly. Her science and social notebooks have half-finished answers on almost every page, and with the half-yearly exams close I can see the gap. She says the teacher rubs the board off before she's done. I'm at the hospital most evenings, so I only see the notebooks at night. Do other parents get notes photographed from a classmate, or is it better to ask the teacher directly? I'd rather fix the speed than keep borrowing, but the exam is in a few weeks.
