My daughter is a college student. During her test she was required to use their online system to log in and answer the questions, then convert the results to PDF and upload to the professor. She answered all questions correctly and converted data to PDF on their site and uploaded as instructed. The PDF however had one blank page (an error) that was deducted from her total score. Her answers were correct but due to circumstances beyond her control there was a faulty PDF. What is the best action?
