I put the answer already and when I was submitting it it said I did not complete the question, but I did and I know it because I did work for every problem on a separate sheet of paper and the correct answer matched the answer I put on my paper. I didn't forget to put the correct answer on the computer because I double checked all the questions if they were answered or not.
