Answer:
So what I would first do is make a schedule or a list.
First list the most important things, which are your two unit assessments, right?
If your other work isn't that bad, you can start working on your unit assessments now. I know, you don't know how to do it. So here are some more tips!
Start the oldest one first: the one that has been overdue the longest. I once came to a school pretty late, and the first thing I had to do was a science unit test! I barely knew anything! So here's what I did:
Research! I always researched what my question was about. And figuring out what the unit is about too. If you learn what the unit is about, you're gonna ace it!
Learning about a whole topic in one night is hard, OBVIOUSLY. So, TURN YOUR PHONE OFF! CLICK OFF ANY DISTRACTING WEBSITES, AND DON'T THINK ABOUT GOING TO PINTEREST! Put on some LYRICLESS music (only if you want), and take out your notebook.
(If you feel you're going to forget something that you researched later, write it down in your notebook.)
Organize your notes. I suggest writing in different colors for different things, to make it a little bit fun! Different pages for different things, too.
Set a limit. Research/study for how long you think you should, I would say 2 hours or less, and then start on your test.
Oops! We've landed on a question we have no idea about! That's okay! We'll just recheck our notes, and see if we've got any info on that. Oh no, we don't! Let's see, is there a topic about this in any of the resources we have?
ALSO, please don't try to cheat by looking up the questions. Maybe that's okay if we really can't get it, but if you couldn't get it, I would just suggest coming back to that question later or making a reasonable guess.
Also, make sure you enjoy it! Even if that joy is only a little bit... I like to pretend I'm doing school with my friends, or that I'm making a video! Yes, I know, I'm a weirdo.
Repeat these steps for the 2nd test!
