Seventh Grade (Please help me for my story!)

So i'm writing a fan fiction about this girl that is in seventh grade.

The problem is that i have NO idea about seventh grade in America so i was wondering if you could just tell me the basics.

Plus, i found a schedule online and i kind of made one of my own and i want to know if it looks seventh grade-ish.

08:00 - 08:45 Homeroom
08:45 – 09:30 English
09:30 – 10:15 Math
10:15 – 11:00 Spanish
11:00 – 11:40 Lunch
11:40 – 12:25 History
12:25 – 1:10 Science
1:10 – 1:55 Studio Art
1:55 – 2:55 P.E

Originally is said
08:00 - 08:15 Homeroom
08:15 - 08:45 Advisory(?) but i have NO idea what it is, do you know?

and what's studio arts??

And does the schedule change from day to day or is it like this through the whole week?
Can you tell me about your seventh grade schedule if you remember??

All kinds of help are welcomed, i've been researching for hours and i would like to get the update out before i go to bed...

LAST QUESTION: Did i spell schedule right o.O?
