Plan it dude.
Plan everything on days.
I always do that. It is annoying, but it works.
Instead of doing that 15 exercise math homework 1 day before the lesson, try making it in 2-3 days.
Sorry I haven't been on or posted much lately, it's just, schools got me caught up with projects and testing... I will be on a lot more during the weekends, so just so you know...I'M ALIVEEEEE
