Hi!  I am restructuring a course to make quizzes worth fewer points.  There are 11 quizzes of 10 questions each in the course.  Originally, each question was worth one point, so each quiz was worth 10 points.  I'd like to make all the questions worth 0.5 points so each quiz is worth 5 points in total.  

Besides going through each question individually and changing the point allocation, is there a way to change them for all the quizzes in bulk?  I'd rather avoid going through each of the 110 questions and changing questions individually if possible (but can if necessary).

Thanks!
