My students do open book assignments and there can be 10-50 questions. This week they submitted answers and when I was grading there is nothing in the answer spot. The student is also not able to see the answer that they know they typed in. I have at least 2 and maybe 3 students that this happened to. They have been doing this for 6 months and just now having trouble.
Any suggestions. I don't know what to do about their grade. They are good students and have always done their work so I do believe them.
Thanks and have a great day!
