Change Grading Option in New Quizzes

[dakotajones]

I recently created my first quiz within the "New Quizzes" option.  It was a matching quiz for vocabulary terms.  I remember at some point I was asked if I wanted to award partial credit and I clicked "no" without even thinking. Now if my students get one of the matching terms incorrect they receive 0/9 points, instead of 8/9 points.  I went back into my new quiz to find the area that I marked the no partial credit option, but it is no where to be found.  I am, also, not being given a choice for partial credit on new quizzes that I create, so I am assuming the system is going to keep my no partial credit option and apply that to all of the quizzes that I create from this time forward.  Please help me fix this issue!
