Math is killing me plz help.

Help im dying

So basically my entire class gets one makeup test at the end of the semester, and I chose to do mine on the quadratics test paper 2 b/c that was my worst paper this semester.

The test is tomorrow and i've only just started studying. I've spent all morning on kahn academy and it seems so easy but i know im gonna walk into class tomorrow and totally flunk that shit.
