What can I do to make myself improve my school grades?
Extra credit...study a lot to get at least b's in your tests do your assignments
study with a friend ?
Listen to quiet acoustic music while studying. :) Birdy, Ed Sheeran, and Norah Jones are my favorites. :) it helps me focus better. :)
Pace yourself and prioritize.
Make time for yourself set a time to study for like an hour or so and don't stop till you know your brain is ready to shut down.
Study, work hard, focus, and repeat.
