I'm having a Pre-SAT tomorrow

Any tips would be gladly appreciated
Don't worry about it. Really.
It doesn't count toward your grade or anything, and all it does is serve as a measure for how you may perform on the actual SAT. It doesn't give a perfect prediction of course, as there are other factors that can affect your score... Still, it helps you get a feel for the way the test is set up.
There are some scholarships and honors out there that you can receive depending by how well you do on the PSAT though...
~And since tomorrow is the PSAT for sophomores and juniors, seniors have declared it "Unofficial Skip Day". For the first three hours of the day, we would nothing but sit in the cafeteria. Waste of time tbh. I could be
sleeping in working on college apps.
But most seniors (including me >_>) are going out to breakfast before heading to school later, when classes actually start. They're not going to start checking attendance for seniors until 4th period starts so yeah...
Then I get to dissect a cow eyeball in psych!
