How to fix student scores on a multiple fill in the blank question

Community Novice

I created a multiple fill in the blank question.  I put in 4-5 possible answers for each blank hoping that I would catch most of the students possible answers. I need to go in and adjust grades for quite a few students.  What is the easiest way to do this?  Go into speed grader and look at each students question?  Can I actually change the quiz or should I just change the score?
