1) Don't scream.

2) Don't give them a formula sheet.  If you do, they will figure that the
physics in on the sheet rather than in their heads -- not just your
students do this -- all students do this -- at least the algebra class does
this -- they spend the night before the test cramming and memorizing and
think they understand the physics.   Physics is conceptual not
mathematical.  In class ask them conceptual questions -- give multi-part
questions of the test and start with a conceptual question of two then ask
for  a calculation.

We've all been there.
