Facts about electricity and magnetism:

stuff id need to know for an exam

You're in luck !  This is gonna be easy.  Listen to this:

On the exam, they're gonna put questions about all that same stuff
that they talked about IN the class all those times !  The exact same
material.  And if they didn't talk about it in class, then it won't be on
the exam !    How cool is that ? !

All that stuff you copied from the board, all those notes you wrote in
your notebook so you'd remember it, all those handouts they gave out
in class, all that homework you did ... THAT's what they'll put on the exam !

It's gonna be all stuff that you seen and heard and studied before.
No surprises.  It'll be a breeze, and you're totally gonna do fine.
