How to get better grades and change my whole life?

I used to be a very good student but in the years I started to decline. Now, I'm in 8th grade and I wat to do good in school but I don't know how to get in the prime that I was in.How to get better grades and change my whole life?
as u reach ur teenage years u become more playful and hanging around friends coz u dint wanna be left out!

well u should limit all these. study and work hard on it.

yes,u can play and hang out,but u must also think of ur future.

u shouldnt depend on others doing things for u



best of luck!

Start studying,

playing less video games and watching less TV



you know stuff like that.
Lots of study and hard work. Good luck!
Get off the computer and do your homework. Less games and more work.
ok so heres what i did

i stoped watching tv because my grades were going way down

it wasnt that i wasnt studying as much but for some reason the not watching tv thing really helped

so now i only watch it sometimes-but never before a test
