We Americans also need to rid ourselves of the imperial system and switch to metric.
Switch the school year system to be more year around we have a two and half month break, Which has been proven reduces how much a student retains.
Also we should adapt a six day school week.
I also believe we need to pay our teachers much more.
In Australia high school is year 7-12
7th and 8th grader will get more freedom.
12 to 14 year olds will get more freedom.
There will be no more Freshman-Senior names for high school and replace by 9th-12th.
Only college will have Freshman-Senior. So yeah it good idea. Anyway this is my opinion.
