Got my report card, doesn't say my average grade!

Hey, I got my report card yesterday, but our school board stopped putting our average grade on the report card.
So, now I'm a little frustrated because I wanted to know what it was :/

I was in grade 7, so that's why there's so many classes. If you can, can you please calculate my average grade?

80% - Religion/Family Life

82% - Language -- Reading
83% - Language -- Writing
91% - Language -- Oral Communication
87% - Language -- Media Literacy

96% - French -- Oral Communication
98% - French -- Reading
88% - French -- Writing

92% - Math -- Number Sense/Numeration
87% - Math -- Geometry/Spacial Sense
92% - Math -- Patterning/Algebra
90% - Math -- Data Management

96% - Science and Technology

85% - History

84% - Health Education
75% - Physical Education

80% - Arts -- Dance
83% - Arts -- Drama
95% - Arts -- Visual Arts

Sorry about all the marks, we have all these classes in one semester 'cause I was in grade 7.
Anyway, can you calculate what my average is? I'm too lazy :P

If all are weighted equally, you take them all and divide them by the number of grades total. In that case,

(80 + 82 + 83 + 91 + 87 + 96 + 98 + 88 + 92 + 87 + 92 + 90 + 96 + 85 + 84 + 75 + 80 + 83 + 95) / 19

1664 / 19 = 87.6%

Cheers!

Clearly your just doing this for attention because you think you did amazing and you want everyone else to see that. Your too lazy to sum up a few numbers and divide but you wrote out a huge essay ?

Your average for everything is a 87.5%. I should get best answer:)

wtf is "religion/family life" is that just what they call brainwashing in your school?
