assigning grade/points to likert questions - want to tally score

I'm attempting to set up a survey-type assessment where the person's manager will use the tool to rate the employee on how s/he delivered a presentation. Rating scale is 1-5, 1 being poor and 5 being outstanding, with total number of questions at 9 and total points possible at 45, with a passing score being 35 or greater out of 45. I've tried a number of different graded question/survey question formats in Quizmaker 13 and can't get the rating on each question to come out as a total at the end -- so is what I'm trying to do even possible in Quizmaker? If so, guidance is appreciated. Then, how do I change the likert scale description (default is strongly agree to strongly disagree)? Thanks for your help.
