Graduation thesis scores are divided into five grades: excellent, good, medium, passing and failing.

There are six events in each grade, each with the same score but different weights. Calculate the total score of six projects according to the weight and score. A total score of more than 90 is excellent, a total score of 80-89 is good, a total score of 70-79 is medium, a total score of 60-69 is qualified, and a total score of less than 60 is unqualified.
