IME lack of time management should be a concern. If the test is really tough, few students will finish, and of those who don't, a lot never get anything scrawled on the last question or two.
Show me what you know, not what you don't. I am generous with even a reasonable restatement of the problem, a short list of equations, and some effort vs throwing stuff together in a haphazard fashion. If you are lost, state what you know and move on.
Put together coherent equations and a logical approach. I would much rather see all the algebra done at once which points to a solution versus numerical answers every step of the way.
Know Newton's laws.

Dance with the gal you brought: if youu have a methodology that has worked in the past, use it. This is not always the best time to realize that energy conservation is better than a purely kinematics approach unless the question asks you for a particular approach.
Rotation: try not to get dizzy and remember that it is only a specialized case of linear principles and equations.
Best of luck.
PS: knowing calculus well, and being able to apply it on the fly is the very best defense!
